WASHINGTON, April 29 (Reuters) - All new passenger cars and trucks sold in the U.S. will be required to have automatic emergency braking systems by September 2029, the National Highway Traffic Safety Administration said on Monday, saying that the rule will save at least 360 lives annually and prevent at least 24,000 injuries.

Automatic emergency braking systems use sensors to detect when vehicles are close to striking another vehicle or pedestrian in front and automatically apply brakes if the driver has not. The rule requires the systems to detect pedestrians in both daylight and at night. (Reporting by David Shepardson; Editing by Leslie Adler)
