(Bloomberg) -- A Tesla car involved in a deadly crash in Florida that’s under investigation because the driver was using automated technology was speeding before striking a truck.
The U.S. National Transportation Safety Board said in a preliminary report Tuesday that the Tesla was traveling at 74 miles (119 kilometers) per hour in a zone where the limit was 65 miles per hour.
The Model S Tesla was being operated by what the car company calls Autopilot. The NTSB called the system “Traffic-Aware Cruise Control and Autosteer.” The car also had an automatic emergency braking system that was designed to slow or stop before a collision, according to the NTSB.
The preliminary report didn’t include any conclusions about why the May 7 collision occurred or whether Tesla’s Autopilot system contains any flaws.
Both the NTSB and the National Highway Traffic Safety Administration are investigating the crash, which killed the driver of the Tesla.
Tesla’s automation didn’t notice the white side of the tractor trailer as it turned in front of the car against a brightly lit sky so the brake wasn’t applied, according to the carmaker. The crash was the first with a known fatality in more than 130 million miles of Autopilot driving, according to Tesla.
