The Office of Defects Investigation of the National Highway Traffic Safety Administration (NHTSA) have opened an investigation (PE21-020) into crashes involving first responder scenes and vehicles manufactured by Tesla. The vehicles involved were operating in either Autopilot or Traffic Aware Cruise Control prior to the accident.
| The Vehicles Affected Include: |
|---|
| 2017-2021 Tesla Model 3 |
| 2014-2021 Tesla Model S |
| 2015-2021 Tesla Model X |
| 2019-2021 Tesla Model Y |
Since January 2018, the NHTSA has identified twelve crashes in which Tesla models of various configurations, encountered first responder scenes and preceded to crash into one or more vehicles involved with those scenes. Most incidents took place after dark and included traffic control measures such as first responder vehicle lights, flares, an illuminated arrow board and road cones. The involved vehicles were all engaged in either Autopilot or Traffic Aware Cruise Control during the approach to the crashes.
Autopilot is an Advanced Driver Assistance System (ADAS) in which the vehicle maintains its speed and lane centring. With the ADAS active, the driver still holds primary responsibility for Object and Event Detection and Response (OEDR), e.g., identification of obstacles in the roadway or adverse maneuvers by other vehicles during the Dynamic Driving Task (DDT).
The NHTSA have opened a Preliminary Evaluation of the SAE Level 2 ADAS system (Autopilot) in the Tesla 3, S, X, and Y models. The investigation will evaluate the methods used to monitor, assist, and enforce the driver’s engagement with the dynamic driving task during Autopilot operation. The investigation will also assess the OEDR by vehicles when engaged in Autopilot mode and ODD in which the Autopilot mode is functional. The investigation will also include examination of the contributing circumstances for the confirmed crashes listed below and other similar crashes.
