Safety Score ^Beta

The Safety Score ^Beta is an assessment of your driving behavior based on several metrics called Safety Factors. These are combined to estimate the likelihood that your driving could result in a future collision. We combine your daily Safety Scores (up to 30 days) to calculate the aggregated Safety Score, displayed on the main ‘Safety Score’ screen of the Tesla app. You can find details around your daily Safety Score by selecting ‘Daily Details’ at the bottom of the screen.

The Safety Score ^Beta is intended to provide drivers transparency and feedback of their driving behaviors to encourage safer driving and potentially pay less for their insurance. The Safety Score is a value between 0 and 100, where a higher score indicates safer driving. Most drivers are expected to have a Safety Score of 80 or above.

To see more details about Safety Score and how it’s calculated, you need to determine if you are currently enrolled in version 1.2, version 2.0, or a previous version. To determine which version you are enrolled in, open the Tesla app and scroll to the bottom of the ‘Safety Score’ screen.

What Changed in Version 2.0

Safety Score version 2.0 features several updates including two new Safety Factors and updates to how your driving behavior is measured and Safety Score is calculated. Here are the key changes from version 1.2 to version 2.0:

Added Excessive Speeding as a new Safety Factor. More time spent driving over 85 mph will lead to a lower Safety Score.
Added Unbuckled Driving as a new Safety Factor. Time spent driving over 10 mph without buckling the driver’s seatbelt will lead to a lower Safety Score.
Updated Late Night Driving to be risk weighted based on when you are driving from 10 PM – 4 AM. The impact of late night driving on your Safety Score will depend on the proportion of time spent driving in each hour from 10 PM – 4 AM. The impact on your Safety Score is now reduced earlier in the night and increased later in the night.
Updated Hard Braking Safety Factor to exclude braking events that occur when the vehicle detects a yellow traffic light.

Note: Availability of these features will vary based on your vehicle’s Infotainment hardware.

Safety Factors

There are several Safety Factors that impact your Safety Score. These are measured directly by your Tesla vehicle using various sensors on the vehicle and Autopilot software.

Forward Collision Warnings per 1,000 Non-Autopilot Miles

Forward Collision Warnings are audible and visual alerts provided to you, the driver, in events where a possible collision due to an object in front of the vehicle is considered likely without your intervention. Events are captured based on the 'medium' Forward Collision Warning sensitivity setting regardless of your user's setting in the vehicle. Forward Collision Warnings are incorporated into the Safety Score formula as a rate per 1,000 non-Autopilot miles. The value is capped at 130.7 per 1,000 non-Autopilot miles in the Safety Score formula.

Hard Braking

Hard braking is defined as backward acceleration, measured by your Tesla vehicle, in excess of 0.3g. This is the same as a decrease in the vehicle’s speed larger than 6.7 mph, in one second. Hard braking is introduced into the Safety Score formula as the proportion of time where the vehicle experiences backward acceleration greater than 0.3g as a percentage of the proportion of time the vehicle experiences backward acceleration greater than 0.1g (2.2 mph in one second). Hard braking while on Autopilot is not factored into the Safety Score formula. For vehicles with Autopilot computer 3.0 or greater, braking while the vehicle detects yellow traffic lights is also not factored into the Safety Score formula. If the vehicle is unable to detect a yellow traffic light at the time of the hard braking, the event will impact your Safety Score. The percentage shown in the app is the proportion of time spent braking done with excessive force when driving and Autopilot is not engaged. The value is capped at 5.8% in the Safety Score formula.

Aggressive Turning

Aggressive turning is defined as left/right acceleration, measured by your Tesla vehicle, in excess of 0.4g. This is the same as an increase in the vehicle’s speed to the left/right larger than 8.9 mph, in one second. Aggressive turning is introduced into the Safety Score formula as the proportion of time the vehicle experiences left or right acceleration greater than 0.4g as a percentage of the proportion of time the vehicle experiences left or right acceleration greater than 0.2g (4.5 mph in one second). Aggressive turning while on Autopilot is not factored into the Safety Score formula. The percentage shown in the app is the proportion of time spent turning with excessive force when driving and Autopilot is not engaged. The value is capped at 15.7% in the Safety Score formula.

Unsafe Following

Your Tesla vehicle measures its own speed, the speed of the vehicle in front and the distance between the two vehicles. Based on these measurements, your vehicle calculates the number of seconds you would have to react and stop if the vehicle in front of you came to a sudden stop. This measurement is called “headway.” Unsafe following is the proportion of time where your vehicle’s headway is less than 1.0 seconds relative to the time that your vehicle’s headway is less than 3.0 seconds. Unsafe following is only measured when your vehicle is traveling at least 50 mph and is incorporated into the Safety Score formula as a percentage. Unsafe following while on Autopilot is not factored into the Safety Score formula. The percentage shown in the app is the percentage of unsafe following when driving and Autopilot is not engaged. The value is capped at 64.2% in the Safety Score formula.

Excessive Speeding

Excessive Speeding is defined as the proportion of time spent driving in excess of 85 mph, as a percentage of the total time driving. The value shown in the app is the proportion of time driven at a speed over 85 mph versus all driving time. The value is capped at 7.6% in the Safety Score formula.

Late Night Driving

Late Night Driving is defined as the number of seconds you spend driving at night (10 PM - 4 AM) divided by the number of seconds you spend driving total during the day and night. Due to the variable risk level associated with driving during each late night hour, each hour is weighed differently, and driving at each hour will affect your Safety Score differently. For example, driving at 10 PM will not affect your Safety Score as heavily as driving at 2 AM. Drive sessions that span two days will apply to the day the trip ends. Late Night Driving includes all driving at night (10 PM – 4 AM) including any driving done on Autopilot. The value is capped at 15.2% in the Safety Score formula.

Forced Autopilot Disengagement

The Autopilot system disengages for the remainder of a trip after you, the driver, have received three audio and visual warnings. These warnings occur when your Tesla vehicle has determined that you have not applied sufficient resistance on the steering wheel or have become inattentive. Forced Autopilot Disengagement is introduced into the Safety Score formula as a 1 or 0 indicator. The value is 1 if the Autopilot system is forcibly disengaged during a trip, and 0 otherwise.

Unbuckled Driving

Unbuckled Driving is defined as the proportion of time spent driving above 10 mph without fastening the driver’s seatbelt, as a percentage of time spent driving above 10 mph. The value shown in the app is the proportion of time driven at a speed over 10 mph, without buckling the driver’s seatbelt, as a percentage of time spent driving over 10 mph. The value is capped at 4.1% in the Safety Score formula.

Determining Your Safety Score

In order to calculate your daily Safety Score, we use the Predicted Collision Frequency (PCF) formula below to predict how many collisions may occur per 1 million miles driven, based on your driving behaviors measured by your Tesla vehicle. Driving on Autopilot (including 5 seconds after Autopilot is disengaged) will not be factored into the Safety Score formula, but the miles driven while on Autopilot are included in the total.

Predicted Collision Frequency (PCF) = 0.83220180	x	1.012555104^{Forward Collision Warnings per 1,000 Non-Autopilot Miles}
	x	1.16460827^{Hard Braking}
	x	1.01498152^{Aggressive Turning}
	x	1.00245084^{Unsafe Following Time}
	x	1.40663310^{Forced Autopilot Disengagement}
	x	1.05018975^{Late Night Driving}
	x	1.00939791^{Excessive Speeding}
	x	1.00901189^{Unbuckled Driving}

The current formula was derived based on statistical modeling using 8 billion miles of fleet data. We expect to make further changes to the formula in the future as we gain more customer and data insights.

The PCF is converted into a 0 to 100 Safety Score using the following formula:

Safety Score = 112.29263237 - 14.77121589

PCF

Your daily Safety Score is not impacted by the number of miles you drive. We combine your daily Safety Scores (up to 30 days) into a mileage-weighted average to calculate the aggregated Safety Score, which is displayed on the main ‘Safety Score’ screen of the Tesla app.

Note: Since vehicles with hardware older than Autopilot computer 2.0 do not measure following distance, Forward Collisions Warnings per 1,000 non-Autopilot miles and Unsafe Following Time is replaced by default values of 15.6 and 22.2% in the PCF formula, respectively. For these vehicles, the value of 112.29263237 is replaced by 115.76503741 in the Safety Score formula.

Improving Your Safety Score

You can improve your Safety Score by improving each Safety Factor.

Forward Collision Warnings per 1,000 Non-Autopilot Miles

Maintain a safe following distance from the vehicle in front to give you enough time to react to slower or stationary vehicles. Pay attention to the other vehicles on the road and reduce speed in traffic congested areas.

Hard Braking

Engage the brake pedal early when slowing down, coming to a stop or reacting to a change in your environment. Use regenerative braking whenever possible and safe to do so. Maintaining a safe following distance reduces the instances where the brake pedal needs to be applied with extreme force.

Aggressive Turning

When turning, changing lanes or rounding a corner, do so gradually. Reduce your speed heading into a turn, gradually accelerating out of the turn. Do not unnecessarily jerk the steering wheel.

Unsafe Following

Do not tailgate or drive close to the vehicle in front. Maintain a following distance of several car-lengths to the vehicle in front to have sufficient time to react to its speed. Remember that driving at higher speeds in inclement weather or on slick road surfaces requires a greater following distance to allow sufficient time to react safely.

Excessive Speeding

Plan a little extra time when commuting so you can arrive on time without driving over 85 mph. Traveling at high speed adds additional risk when driving, so paying close attention to your speed and following the speed limit can help reduce potential risk and raise your Safety Score.

Late Night Driving

Plan your trips to avoid driving between the hours of 10 PM and 4 AM to help reduce the likelihood of a dangerous driving environment.

Forced Autopilot Disengagement

Only use the various Autopilot features as described in your Owner’s Manual. Pay attention to the road and maintain your hands on the steering wheel while the Autopilot system is engaged. Autosteer detects your hands by recognizing slight resistance as the steering wheel turns, or from you manually turning the steering wheel very lightly (without enough force to take over steering). Autosteer also qualifies your hands as being detected if you engage a turn signal or use a button or scroll wheel on the steering wheel.

Unbuckled Driving

Build a habit of fastening your seatbelt in the driver’s seat before you shift out of park. Even at slow speeds, wearing your seatbelt is an easy way to help reduce risk while driving and avoid serious injury.

When available for your vehicle, you will see ‘Safety Score’ on the home screen of the Tesla app. To receive a Safety Score:

Your vehicle must be on software update 2023.2.12 or later (2021.24.25 or later for Tegra vehicles) or be enrolled in FSD Beta version 11.3 or higher. To check the latest software version on your car, tap ‘Software’ on your touchscreen.

Your vehicle must be connected to a cellular or Wi-Fi network.

You need to take a trip that’s at least 0.1 miles on your vehicle.
In the event that your vehicle does not have cellular connectivity while on a trip, you may not receive immediate feedback upon the end of your trip. You will receive your updated driving information and Safety Score once your vehicle has connectivity. Premium Connectivity is not required to receive a Safety Score.
In order to provide you real-time feedback on your driving safety, every time you take a trip in your Tesla vehicle, your Safety Score for that day will be updated. At the end of each day, your Safety Score for that day will no longer change — any subsequent trips will be used to determine your Safety Score for the following days.

In the event that you do not have cellular connectivity, you may not receive immediate feedback upon the end of your trip. You will receive your updated driving information once you have connectivity.
Changes to your current insurance policy are only permitted at renewal. If you are being upgraded, we will send you a notice approximately two months before your next renewal date. Review your policy documents in the Tesla app to determine your next renewal date and compare your next renewal date with the renewal effective date for the latest version of Safety Score listed for your state. If your next renewal date is on or after the renewal date listed for your state, then you will be moved to the newest version of Safety Score at renewal.
Tesla captures driving over all trips, where a trip consists of any driving (including reversing and Autopilot usage) occurring between the time the vehicle is powered on and able to be driven to the time the vehicle is powered off. Any driving and accrued mileage occurring while in service mode is excluded. Trips less than 0.1 miles will be excluded from scoring calculations. Driving on Autopilot (including 5 seconds after Autopilot is disengaged) will not be factored into the Safety Score formula, but the miles driven while on Autopilot are included in the total.
The Safety Score formula ignores any events that occur while Autopilot is engaged (including 5 seconds after the Autopilot is disengaged). This does not include Forced Autopilot Disengagements or Late Night Driving, which will impact your Safety Score. Any events that occur while a driver is manually engaging the acceleration pedal while on Traffic Aware Cruise Control will count towards the Safety Score.

Miles driven while Autopilot is engaged are not used to determine the Forward Collision Warnings per 1,000 Miles. Miles driven on Autopilot are not considered when calculating the mileage-weighted Safety Score.
Events that happen during times when Autopilot is engaged are not counted towards your Safety Score, unless you override Traffic Aware Cruise Control with the accelerator pedal. These events will appear in your trip timeline view. The event will show “Acceleration Override” next to the time in the list of events.

How are different hours weighed by Late Night Driving?

In Safety Score version 2.0, Late Night Driving hours are weighed differently to better reflect the amount of risk associated with driving at those times. The following table illustrates how each hour from 10 PM – 4 AM is weighed in the Safety Score formula:

The final contribution of your late night driving to your Safety Score is calculated as:

Late Night Driving = Risk Weighted Late Night Driving (seconds)

Total driving time (seconds)

Where Risk Weighted Late Night Driving (seconds) is defined as:

0.23558	x	Driving time between 10 PM and 11 PM (seconds)	+
0.42669	x	Driving time between 11 PM and 12 AM (seconds)	+
0.61779	x	Driving time between 12 AM and 1 AM (seconds)	+
0.80890	x	Driving time between 1 AM and 2 AM (seconds)	+
1.00000	x	Driving time between 2 AM and 3 AM (seconds)	+
0.33312	x	Driving time between 3 AM and 4 AM (seconds)

Times on trips are based on the time zone of the vehicle at the end of the trip. When a Daylight Savings time change occurs during your trip, the amount of Late Night Driving time is the amount of time you drove during the hours of 10 PM and 4 AM. This means that during the Spring and Fall time changes, we do not count the addition of an extra hour or removal of an hour due to Daylight Savings time.
Your Tesla vehicle relies on its cameras and firmware to detect yellow traffic lights. It may not detect all yellow traffic lights. Examples of situations that could lead to undetected yellow traffic lights include when the cameras are obscured or do not have line of sight of the traffic signals, inclement weather, or low light environments.

Yellow traffic light detection is only available on vehicles with Autopilot computer 3.0 or later.
Your Tesla vehicle provides you with a range of safety features that include warnings and alerts to help protect you, your passengers, other drivers and pedestrians around you. View the Owner’s Manual for specific details about the various safety features in your vehicle.

Review the following to learn more about how an event contributes to each Safety Factor:

Forward Collision Warnings per 1,000 Non-Autopilot Miles
Forward Collision Warnings produce audio and visual alerts when a possible collision with an object in front of the vehicle is considered likely without your intervention. Events are captured based on the ‘medium’ Forward Collision Warning sensitivity setting regardless of your user’s setting in the vehicle. You may not see or hear the alert if your setting is less sensitive.

Hard Braking
No audio or visual alerts are provided if you brake with excessive force. In some cases, the anti-lock braking system (ABS) which prevents the wheels from locking when you apply maximum brake pressure, may be activated, and you will see the ABS alert. If you apply the brakes with extreme force, you may feel like you are being pulled forward into your seatbelt, away from the seat.

Aggressive Turning
No audio or visual alerts are provided if you turn with excessive force. If you take a turn with extreme force, you may feel the sensation of being pulled away from the direction you are turning.

Unsafe Following Time
Your Tesla vehicle does not provide you with any audio or visual alerts when you are following at an unsafe following distance. You may receive a Forward Collision Warning if your following distance makes collision with the vehicle in front likely.

Excessive Speeding
Your Tesla vehicle displays the vehicle’s speed which can be used to determine when you are driving over 85 mph. No separate audio or visual alerts are provided if you drive over 85 mph.

Late Night Driving
Your Tesla vehicle displays the vehicle’s local time which can be used to determine when you are driving between 10 PM and 4 AM. No separate audio or visual alerts are provided if you drive within these hours.

Forced Autopilot Disengagement
Your Tesla vehicle will provide three audio and visual warnings before the Autopilot system is disengaged due to inattentiveness. Please refer to the Owner’s Manual in your vehicle for details of these alerts and the circumstances in which the Autopilot system will disengage.

Unbuckled Driving
Your Tesla vehicle displays the vehicle’s speed which can be used to determine if you are driving over 10 mph without wearing your seatbelt. Your vehicle will provide an audio alert if you are driving without buckling your seatbelt. There are no audio or visual alerts to specifically indicate if you’re driving over 10 mph without buckling the driver’s seatbelt.
Your Safety Score is vehicle specific. If you have more than one Tesla vehicle, each one of your Tesla vehicles will have its own Safety Score.
If the vehicle ownership changes, the Safety Score data previously collected will neither be used for the vehicle under the new owner, nor will it be used for a new Tesla vehicle you purchase.

What Changed in Version 1.2

Safety Score version 1.2 features several updates including a new Safety Factor and updates to how your driving behavior is measured and Safety Score calculated. Here are the key changes from version 1.0 to version 1.2:

Provided a visualization of your trip, as a timeline, to show when specific events that impacted your Safety Score occurred. To protect your privacy, no location data is provided.
Added Late Night Driving as a new Safety Factor. More time spent driving at night will lead to a lower Safety Score.
Increased grace period after Autopilot disengages from 3 seconds to 5 seconds.
Updated hard braking and aggressive turning Safety Factors to count the number of events instead of the duration of events.
Updated Forward Collision Warning rate Safety Factor to calculate the rate of warnings per 1,000 miles driven while not using Autopilot.
Updated Safety Score to use the miles-weighted average of the last 30 day’s Safety Scores, ignoring any miles driven on Autopilot.

Safety Factors

There are several Safety Factors that impact your Safety Score. These are measured directly by your Tesla vehicle using various sensors on the vehicle and Autopilot software.

Forward Collision Warnings per 1,000 Non-Autopilot Miles

Forward Collision Warnings are audible and visual alerts provided to you, the driver, in events where a possible collision due to an object in front of the vehicle is considered likely without your intervention. Events are captured based on the 'medium' Forward Collision Warning sensitivity setting regardless of your user's setting in the vehicle. Forward Collision Warnings are incorporated into the Safety Score formula as a rate per 1,000 non-Autopilot miles. The value is capped at 117.5 per 1,000 non-Autopilot miles in the Safety Score formula.

Hard Braking

Hard braking is defined as backward acceleration, measured by your Tesla vehicle, in excess of 0.3g. This is the same as a decrease in the vehicle’s speed larger than 6.7 mph, in one second. Hard braking is introduced into the Safety Score formula as the number of times where the vehicle experiences backward acceleration greater than 0.3g as a percentage of the number of times the vehicle experiences backward acceleration greater than 0.1g (2.2 mph in one second). Hard braking while on Autopilot is not factored into the Safety Score formula. The percentage shown in the app is the proportion of brakes done with excessive force when driving and Autopilot is not engaged. The value is capped at 10.9% in the Safety Score formula.

Aggressive Turning

Aggressive turning is defined as left/right acceleration, measured by your Tesla vehicle, in excess of 0.4g. This is the same as an increase in the vehicle’s speed to the left/right larger than 8.9 mph, in one second. Aggressive turning is introduced into the Safety Score formula as the number of times the vehicle experiences left or right acceleration greater than 0.4g as a percentage of the number of times the vehicle experiences left or right acceleration greater than 0.2g (4.5 mph in one second). Aggressive turning while on Autopilot is not factored into the Safety Score formula. The percentage shown in the app is the proportion of turns done with excessive force when driving and Autopilot is not engaged. The value is capped at 22.9% in the Safety Score formula.

Unsafe Following

Forced Autopilot Disengagement

Late Night Driving

Late Night Driving is defined as the number of seconds you spend driving at night (10 PM - 4 AM) divided by the number of seconds you spend driving total during the day and night. Drive sessions that span two days will apply to the day the trip ends. Late Night Driving includes all driving at night including any driving done on Autopilot. The value is capped at 29.3% in the Safety Score formula.

Determining Your Safety Score

Predicted Collision Frequency (PCF) = 0.41978002	x	1.01078171^{Forward Collision Warnings per 1,000 Non-Autopilot Miles}

Safety Factors

There are several Safety Factors that impact your Safety Score. These are measured directly by your Tesla vehicle using various sensors on the vehicle and Autopilot software.

Forward Collision Warnings per 1,000 Miles

Forward Collision Warnings are audible and visual alerts provided to you, the driver, in events where a possible collision due to an object in front of the vehicle is considered likely without your intervention. Events are captured based on the 'medium' Forward Collision Warning sensitivity setting regardless of your user's setting in the vehicle. Forward Collision Warnings while on Autopilot are not factored into the Safety Score formula. Forward Collision Warnings are incorporated into the Safety Score formula at a rate per 1,000 miles. The value is capped at 101.9 per 1,000 miles in the Safety Score formula.

Hard Braking

Hard braking is defined as backward acceleration, measured by your Tesla vehicle, in excess of 0.3g. This is the same as a decrease in the vehicle’s speed larger than 6.7 mph, in one second. Hard braking is introduced into the Safety Score formula as the proportion of time (expressed as a percentage) where the vehicle experiences backward acceleration greater than 0.3g relative to the proportion of time where the vehicle experiences backward acceleration greater than 0.1g (2.2 mph in one second). Hard braking while on Autopilot is not factored into the Safety Score formula. The percentage shown in the app is the percentage of manual braking that is done with excessive force when driving and Autopilot is not engaged. The value is capped at 7.4% in the Safety Score formula.

Aggressive Turning

Aggressive turning is defined as left/right acceleration, measured by your Tesla vehicle, in excess of 0.4g. This is the same as an increase in the vehicle’s speed to the left/right larger than 8.9 mph, in one second. Aggressive turning is introduced into the Safety Score formula as the proportion of time (expressed as a percentage) where the vehicle experiences lateral acceleration greater than 0.4g, in either the left or right direction, relative to the proportion of time where the vehicle experiences acceleration greater than 0.2g (4.5 mph in one second), in either the left or right direction. Aggressive turning while on Autopilot is not factored into the Safety Score formula. The percentage shown in the app is the percentage of turning that is done with excessive force when driving and Autopilot is not engaged. The value is capped at 17.1% in the Safety Score formula.

Determining Your Safety Score

In order to calculate your daily Safety Score, we use the Predicted Collision Frequency (PCF) formula below to predict how many collisions may occur per 1 million miles driven, based on your driving behaviors measured by your Tesla vehicle. Driving on Autopilot (including 3 seconds after Autopilot is disengaged) will not be factored into the Safety Score formula, but the miles driven while on Autopilot are included in the total.

Predicted Collision Frequency (PCF) = 0.682854	x	1.014495^{Forward Collision Warnings per 1,000 Miles}

Note: Since vehicles with hardware older than Autopilot computer 2.0 do not measure following distance, Forward Collisions Warnings per 1,000 Miles and Unsafe Following Time is replaced by default values of 10.2 and 15.8% in the PCF formula, respectively. For these vehicles, the value of 115.382324 is replaced by 118.23762166 in the Safety Score formula.

Frequently Asked Questions

What’s required for me to get a Safety Score for my Tesla vehicle?

When available for your vehicle, you will see 'Safety Score' on the home screen of the Tesla app. To receive a Safety Score:

Your vehicle must be on software update 2021.32.10 or later (2021.24.25 or later for Tegra vehicles). To check the latest software version on your car, tap 'Software' on your touchscreen.
Your vehicle must be connected to a cellular or Wi-Fi network.
You need to take a trip that’s at least 0.1 miles on your vehicle.

Will I receive a Safety Score if I don’t have connectivity?

In the event that your vehicle does not have cellular connectivity while on a trip, you may not receive immediate feedback upon the end of your trip. You will receive your updated driving information and Safety Score once your vehicle has connectivity. Premium Connectivity is not required to receive a Safety Score.

How often will my Safety Score be updated?

In order to provide you real-time feedback on your driving safety, every time you take a trip in your Tesla vehicle, your Safety Score for that day will be updated. At the end of each day, your Safety Score for that day will no longer change — any subsequent trips will be used to determine your Safety Score for the following days.

In the event that you do not have cellular connectivity, you may not receive immediate feedback upon the end of your trip. You will receive your updated driving information once you have connectivity.

Is all my driving captured?

Tesla captures driving over all trips, where a trip consists of any driving (including reversing and Autopilot usage) occurring between the time the vehicle is powered on and able to be driven to the time the vehicle is powered off. Any driving and accrued mileage occurring while in service mode is excluded. Trips less than 0.1 miles will be excluded from scoring calculations. Driving on Autopilot (including 3 seconds after Autopilot is disengaged) will not be factored into the Safety Score formula, but the miles driven while on Autopilot are included in the total.

I had a Forward Collision Warning while Autopilot was engaged. Will my Safety Score be impacted?

No. The Safety Score formula ignores any events (not just Forward Collision Warnings) that occur while Autopilot is engaged (including 3 seconds after the Autopilot is disengaged) and appropriately utilized. This does not include Forced Autopilot Disengagement.

Events that occur while you override Traffic Aware Cruise Control with the accelerator pedal will impact your Safety Score.

Miles driven while Autopilot is engaged is used to determine the Forward Collision Warnings per 1,000 Miles. Miles driven on Autopilot are also considered when calculating the mileage-weighted Safety Score.

How will I know that I have experienced an event that would contribute to my Safety Factors and Safety Score?

Your Tesla vehicle provides you with a range of safety features that include warnings and alerts to help protect you, your passengers, other drivers and pedestrians around you. View the Owner’s Manual for specific details about the various safety features in your vehicle.

Review the following to learn more about how an event contributes to each Safety Factor:

Forward Collision Warnings per 1,000 Miles
Forward Collision Warnings produce audio and visual alerts when a possible collision with an object in front of the vehicle is considered likely without your intervention. Events are captured based on the 'medium' Forward Collision Warning sensitivity setting regardless of your user's setting in the vehicle. You may not see or hear the alert if your setting is less sensitive.
Hard Braking
No audio or visual alerts are provided if you brake with excessive force. In some cases, the anti-lock braking system (ABS) which prevents the wheels from locking when you apply maximum brake pressure, may be activated, and you will see the ABS alert. If you apply the brakes with extreme force, you may feel like you are being pulled forward into your seatbelt, away from the seat.
Aggressive Turning
No audio or visual alerts are provided if you turn with excessive force. If you take a turn with extreme force, you may feel the sensation of being pulled away from the direction you are turning.
Unsafe Following Time
Your Tesla vehicle does not provide you with any audio or visual alerts when you are following at an unsafe following distance. You may receive a Forward Collision Warning if your following distance makes collision with the vehicle in front likely.
Forced Autopilot Disengagement
Your Tesla vehicle will provide three audio and visual warnings before the Autopilot system is disengaged due to inattentiveness. Please refer to the Owner’s Manual in your vehicle for details of these alerts and the circumstances in which the Autopilot system will disengage.

How does my Safety Score work if I have more than one vehicle?

Your Safety Score is vehicle specific. If you have more than one Tesla vehicle, each one of your Tesla vehicles will have its own Safety Score.

What happens to my Safety Score if I sell my vehicle?

If the vehicle ownership changes, the Safety Score data previously collected will not be used for the vehicle under the new owner, nor will it be used for a new Tesla vehicle you purchase.
