Safety Score

Safety Score assesses your driving behavior using several metrics called Safety Factors. These are combined to estimate the likelihood of a future collision. We combine your daily Safety Scores (up to 30 days) to calculate your aggregated Safety Score, which is displayed on the main ‘Safety Score’ screen of the Tesla app. You can find details regarding your daily Safety Score by selecting ‘Daily Breakdown’ at the bottom of the screen.

Safety Score is intended to provide drivers transparency and feedback regarding their driving behaviors, encourage safer driving and potentially reduce the cost of insurance. Safety Scores are a value between 0 and 100, where a higher score indicates safer driving.

To see more details about Safety Score and how it is calculated, you need to determine if you are currently enrolled in version 3.0, version 2.2 or a previous version. To determine which version you are enrolled in, open your Tesla app and scroll to the bottom of the ‘Safety Score’ screen. See when you will be upgraded to the latest version of the Safety Score.

What Changed in Version 3.0

Safety Score version 3.0 has improved the assessment of your future collision risk based on over 26.5 billion miles of driving data. The key changes from version 2.2 to version 3.0 are:

Safety Factors are now measured against miles driven without FSD (Supervised) engaged, ensuring your score focuses on your manual driving behavior.
Miles driven with FSD (Supervised) engaged receive a Safety Score of 100 and are included in the calculation of Safety Score with FSD (Supervised). Your Safety Score with FSD (Supervised) is calculated by adding the percentage of miles driven with FSD (Supervised) engaged multiplied by 100, to the percentage of miles driven manually multiplied by your Safety Score.
The risk levels assigned to the hours for Late-Night Driving have been refined based on the most recent data.

Note: Availability of Safety Factors will vary based on your Tesla vehicle’s Infotainment system and Self-Driving hardware. Feature availability depends on vehicle configuration, hardware, software version, region, model, vehicle trim and model year.

Safety Factors

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

Note: Feature availability depends on vehicle configuration, hardware, software version, region, model, vehicle trim and model year.

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 without FSD (Supervised) engaged, based on driving behaviors measured by your Tesla vehicle. Driving with Traffic-Aware Cruise Control (TACC), Autosteer or FSD (Supervised) engaged (including 5 seconds after TACC, Autosteer or FSD (Supervised) is disengaged) will not be factored into the Safety Score formula.

Predicted Collision Frequency (PCF) = 0.32781770	x 1.25903299^{Hard Braking}
	x 1.00776995^{Aggressive Turning}
	x 1.00189173^{Unsafe Following Time}
	x 1.18097634^{Forced Autosteer or FSD (Supervised) Disengagement}
	x 1.03013387^{Late-Night Driving}
	x 1.03980607^{Excessive Speeding}
	x 1.01098983^{Unbuckled Driving}

The current formula was derived based on statistical modeling using over 26.5 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 = 118.82842732- 57.43566398x 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 an average, weighted by miles driven while TACC, Autosteer or FSD (Supervised) is disengaged to calculate the aggregated Safety Score.

To calculate the Safety Score with FSD (Supervised) displayed on the main screen of the Tesla app, we combine your aggregated Safety Score described above with the Safety Score for FSD (Supervised), which is 100, weighted by the amount you drove with FSD (Supervised) engaged.

Safety Score with FSD (Supervised) = % of Miles with FSD (Supervised) engaged x 100 + % of Miles with FSD (Supervised) disengaged x Safety Score

The percentage of miles driven with and without FSD (Supervised) engaged is calculated based on the same 30-day window.

Note: Because Tesla vehicles with hardware older than computer 2.0 do not measure following distance, Unsafe Following Time is replaced by a default value of 22.0% in the PCF formula. For these vehicles, the value of 118.82842732 is replaced by 119.62719638 in the Safety Score formula.

Improving Your Safety Score

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

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 it is possible and safe to do so. Maintaining a safe following distance reduces the instances where the brake pedal needs to be applied with excessive force.

Aggressive Turning

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

Unsafe Following

Do not tailgate or drive close to the vehicle in front of you. Maintain a safe following distance of several car-lengths from 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 or significantly exceeding the speed of the vehicles around you. Traveling at high speeds or much faster than surrounding traffic adds additional risk when driving. Always maintain a safe and consistent speed and pay attention to the other vehicles on the road, especially in traffic-congested areas, to help reduce potential risk and improve your Safety Score.

Late-Night Driving

Plan your trips to avoid driving between the hours of 11 PM and 4 AM to help reduce the likelihood of a dangerous driving environment.

Forced Autosteer or FSD (Supervised) Disengagement

Only use the various features as described in your Tesla Owner’s Manual. Pay attention to the road and maintain your hands on the steering wheel while the Self-Driving system is engaged.

Note: Feature availability depends on vehicle configuration, hardware, software version, region, model, vehicle trim and model year.

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 and avoid serious injury.

Tesla captures driving over all trips, where a trip consists of any driving (including reversing and Traffic-Aware Cruise Control (TACC), Autosteer or FSD (Supervised) usage) occurring between the time the Tesla 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, as long as service mode was engaged for the entirety of the trip. Trips less than 0.1 miles will be excluded from scoring calculations. Driving while TACC, Autosteer or FSD (Supervised) is engaged (including 5 seconds after TACC, Autosteer or FSD (Supervised) is disengaged) will not be factored into the Safety Score formula.
Your Safety Score is weighted by miles driven while TACC, Autosteer or FSD (Supervised) is disengaged, excluding five seconds after TACC, Autosteer or FSD (Supervised) is disengaged. This does not include Forced Autosteer or FSD (Supervised) 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.
Events that happen during times when TACC, Autosteer or FSD (Supervised) 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.
In Safety Score version 3.0, 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 11 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:

0.63483 x Driving time between 11 PM and 12 AM (seconds) +

0.67309 x Driving time between 12 AM and 1 AM (seconds) +

1.00000 x Driving time between 1 AM and 2 AM (seconds) +

0.95997 x Driving time between 2 AM and 3 AM (seconds) +

0.41009 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, 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 an undetected yellow traffic light 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 Full Self-Driving 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. Review 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:

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 an alert 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 or 20% faster than the vehicle in front of you, when that vehicle is driving at least 25 mph and within 100 meters. No separate audio or visual alerts are provided if you drive over 85 mph or 20% faster than the vehicle in front of you.

Late-Night Driving
Your Tesla vehicle displays the vehicle’s local time which can be used to determine when you are driving between 11 PM and 4 AM. No separate audio or visual alerts are provided if you drive within these hours.

Forced Autosteer or FSD (Supervised) Disengagement
Your Tesla vehicle will provide three audio and visual warnings before the Self-Driving system is disengaged due to inattentiveness. Refer to the Owner’s Manual in your vehicle for details of these alerts and the circumstances in which the Self-Driving 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.
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. If you sell your Tesla vehicle, it is your responsibility to remove the vehicle from your Tesla app.
On any given day, your Safety Score is primarily based on your driving activity when TACC, Autosteer or FSD (Supervised) are disengaged. If most of your driving on a given day is with TACC, Autosteer or FSD (Supervised) engaged, your Safety Score will likely be lower, as only a small portion of that day’s driving was without TACC, Autosteer or FSD (Supervised) engaged. While your Safety Score for that day may be low, the weighted average Safety Score that is used to determine your insurance premium is weighted by miles driven while TACC, Autosteer or FSD (Supervised) is disengaged. Because those miles are low on this hypothetical day, it will not have a significant impact on your average score. Additionally, if most of your driving is with FSD (Supervised) engaged, your Safety Score with FSD (Supervised) will be even less influenced by manual driving because it is weighted based on the percentage of miles you drive with FSD (Supervised) engaged.

Note: Feature availability depends on vehicle configuration, hardware, software version, region, model, vehicle trim and model year.
