01:59 PM EDT, 05/31/2024 (MT Newswires) -- Amazon.com ( AMZN ) has been asked by the US National Highway Traffic Safety Administration for additional information on its self-driving Zoox vehicles following unexpected braking that caused two rear-end collisions, Reuters reported Friday, citing the regulator.

The road safety regulator, which opened the investigation into the crashes earlier this month, is requesting video footage of the crashes and documents related to the vehicles, the report said.

NHTSA said it was concerned that unexpected rapid braking by vehicles could raise the risk of crashes, especially for drivers who might not anticipate or respond quickly to the sudden braking, Reuters reported.

Amazon ( AMZN ) and NHTSA did not immediately respond to MT Newswires' requests for comment.

Amazon ( AMZN ) shares were down more than 2% in recent trading.
