The US National Highway Traffic Safety Administration is launching a preliminary investigation into the Autopilot function on the Tesla Model S following a fatal accident in Florida.

Autopilot, introduced to the Model S in October 2015, forms part of Tesla’s incremental rollout of technology to facilitate driver autonomy.

According to the company, the hardware consists of a forward radar, a forward-looking camera, 12 long-range ultrasonic sensors positioned to sense 16 feet around the car in every direction at all speeds, and a high-precision digitally-controlled electric assist braking system.

Tesla said that the accident occurred on a divided highway with Autopilot engaged when a tractor-trailer drove across the highway perpendicular to the Model S.

In a statement the company said: “Neither Autopilot nor the driver noticed the white side of the tractor trailer against a brightly lit sky, so the brake was not applied.

“The high ride height of the trailer combined with its positioning across the road and the extremely rare circumstances of the impact caused the Model S to pass under the trailer, with the bottom of the trailer impacting the windshield of the Model S.”
