1. Introduction to Tesla Safety Score

Tesla introduced the Safety Score feature in October 2021 as a dynamic driving behavior assessment tool. Initially designed to vet drivers for the Full Self-Driving (FSD) Beta program, it later expanded to influence Tesla Insurance premiums in eligible U.S. states.

Using real-time telemetry and Autopilot sensors, the system evaluates various aspects of driving behavior across multiple metrics. Scores range from 0 to 100, with higher numbers reflecting safer driving habits.

The Safety Score serves two primary purposes:

  1. It determines eligibility for Tesla's FSD Beta program, with higher scores giving drivers priority access
  2. It impacts insurance premiums for Tesla Insurance customers in certain states, potentially offering significant discounts for safe drivers

2.The Original Safety Score Calculation (2021)

When first launched in October 2021, Tesla's Safety Score focused on five key metrics:

Forward Collision Warnings

  • Triggered when the car predicts a collision risk (set to medium sensitivity)
  • Measured per 1,000 miles driven

Hard Braking

  • Defined as backward acceleration greater than 0.3g
  • Equivalent to decelerating more than 6.7 mph in one second

Aggressive Turning

  • Defined as lateral acceleration greater than 0.4g
  • Equivalent to increasing turning speed by more than 8.9 mph in one second

Unsafe Following

  • Time spent with less than 1-second gap to the car ahead
  • Only measured at speeds above 50 mph

Forced Autopilot Disengagement

  • Occurs after three ignored warnings
  • Scored as either 0 or 1 (binary factor)

Tesla calculated the score using a 30-day rolling average, with a rumored threshold of 80+ needed for FSD Beta access, though this was never officially confirmed.

3.Safety Score Evolution and Updates

Tesla has made several updates to the Safety Score system since its initial release:

Version 1.2 (2021-2023)

This update introduced important changes to the calculation formula:

  • Added a sixth factor: Late-Night Driving (time spent driving between 10 PM and 4 AM)
  • Adjusted caps for various metrics:
    • Forward Collision Warnings capped at 130.7 per 1,000 miles
    • Hard Braking capped at 3.8%

Version 2.0 (March 2024)

This major update expanded the scoring system to include eight factors:

  • Added two new metrics:
    1. Excessive Speeding (time spent driving above 85 mph)
    2. Unbuckled Driving (time spent driving without seatbelts fastened)
  • Retained the six previous factors with some adjustments

Version 2.1 (2024)

This minor update focused on refining the Late-Night Driving parameter:

  • Adjusted the Late-Night Driving window to 11 PM–4 AM (previously 10 PM-4 AM)
  • This change was made to reduce penalties for evening commuters

Version 2.2 (April 2025)

The most recent update (as of April 2025) made substantial changes to the formula:

  • Removed Forward Collision Warnings completely from the formula
    • This change was made due to community feedback about false alerts
  • Refined the Excessive Speeding metric:
    • Now accounts for driving above 85 mph OR
    • Driving more than 20% faster than traffic ahead (if the lead car is moving faster than 25 mph)
  • Increased caps for several metrics:
    • Hard Braking cap raised to 5.2% (previously 3.8%)
    • Aggressive Turning cap raised to 13.2%
Version Year Key Changes
Original 2021 5 factors: Collision Warnings, Hard Braking, Aggressive Turning, Unsafe Following, Autopilot Disengagement
1.2 2021-2023 Added Late-Night Driving (10 PM-4 AM); adjusted metric caps
2.0 2024 Added Excessive Speeding and Unbuckled Driving
2.1 2024 Adjusted Late-Night Driving to 11 PM-4 AM
2.2 2025 Removed Collision Warnings; refined Excessive Speeding; increased caps for Hard Braking and Aggressive Turning

4.How to Improve Your Safety Score

With the latest Safety Score v2.2 metrics in mind, here are effective strategies to maintain or improve your score:

Avoid Hard Braking

  • Use regenerative braking when possible
  • Anticipate stops early and gradually reduce speed
  • Maintain proper following distance to avoid sudden braking
  • Be alert to traffic patterns ahead of you

Take Turns Smoothly

  • Reduce speed before entering turns, not during
  • Keep lateral acceleration under 0.4g
  • Take corners at appropriate speeds
  • Avoid sudden steering inputs

Maintain Safe Following Distance

  • Keep a minimum 2-second gap from cars ahead (3+ seconds is better)
  • Increase distance in poor weather conditions
  • Use Autopilot responsibly to maintain consistent following

Limit Late-Night Driving

  • Avoid driving between 11 PM and 4 AM when possible
  • If late-night driving is necessary, be extra cautious

Watch Your Speed

  • Stay below 85 mph at all times
  • Don't drive significantly faster than surrounding traffic
  • Be especially cautious when passing other vehicles

Always Wear Seatbelts

  • Ensure all passengers are buckled up before moving
  • This is both a safety priority and a scoring factor

Use Autopilot Appropriately

  • Respond promptly to attention reminders
  • Keep hands on the wheel as required
  • Remain responsible and attentive while using Autopilot

5.Impact on Tesla Insurance & FSD Access

The Safety Score has significant practical implications for Tesla owners:

FSD Beta Access

  • High scores (historically around 80+) unlock FSD Beta testing access
  • Better scores may provide earlier access when new FSD versions are released
  • The specific threshold may vary based on Tesla's current testing needs

Insurance Premiums

  • In 12 U.S. states (excluding California), Safety Scores directly affect monthly rates
  • Potential savings:
    • A score of 90+ could lower premiums by 10–20%
    • Excellent scores (95+) may reduce rates by 20-30%
  • Risk factors:
    • Excessive speeding or late-night driving can increase costs by 5–15%
    • Poor scores may result in premium increases

The real-time nature of this insurance model means premiums can adjust monthly based on recent driving behavior, creating immediate financial incentives for safe driving.

6.Common Questions and Misconceptions
  • Has the Forward Collision Warning issue been resolved?

Yes, as of April 2025 (Version 2.2), Tesla has completely removed Forward Collision Warnings from the Safety Score calculation due to community feedback about false alerts.

  • How does the new Excessive Speeding metric work?

The updated metric now considers not just absolute speed (above 85 mph) but also relative speed compared to surrounding traffic. You'll be penalized for driving more than 20% faster than the vehicle ahead of you (if that vehicle is traveling above 25 mph).

  • Do the increased caps for Hard Braking and Aggressive Turning make it easier to maintain a good score?

Yes, the increased caps (Hard Braking now 5.2%, Aggressive Turning now 13.2%) provide more leeway for occasional harder braking or turning without severely impacting your score.

  • How long does it take to improve a low score?

The Safety Score remains a 30-day rolling average. Consistently safe driving will gradually improve your score over time, with newer drives having more impact than older ones.

  • Does Autopilot use affect my score?

Miles driven on Autopilot generally don't count toward most metrics except for forced disengagements. However, you remain responsible for the vehicle at all times.

Can I see my score without Tesla Insurance?

Yes, all Tesla owners in participating regions can view their Safety Score through the Tesla app regardless of insurance provider

7.Conclusion

   Tesla's Safety Score continues to evolve, with the latest Version 2.2 (April 2025) bringing significant improvements based on user feedback and real-world data. The removal of Forward Collision Warnings addresses a major community concern, while refinements to the Excessive Speeding metric and increased caps for certain factors create a more balanced evaluation system.

   For Tesla owners, understanding these changes provides both practical financial benefits through insurance savings and encourages safer driving habits. As Tesla continues to refine the system, we can expect even more accurate assessments of driving safety.

   Whether you're aiming to access FSD Beta features or simply reduce your insurance premiums, staying informed about Safety Score updates and maintaining awareness of your driving habits can make your Tesla ownership experience both safer and more cost-effective.
