U.S. auto safety regulators say they have taken the first step toward requiring devices in vehicles that prevent drunk or impaired driving.

The National Highway Traffic Safety Administration announced on Tuesday that it is starting the process to put a new federal safety standard in place requiring the technology in all new passenger vehicles.

Such devices were required in the Bipartisan Infrastructure Law that was passed by Congress in 2021.

The agency says an advance notice of proposed rule making will help it gather information about the state of technology to detect impaired driving. The regulation would set standards for the devices once technology is mature, NHTSA said in a statement.
