New cars sold in the U.S. must have backup cameras to help drivers avoid accidents under a federal regulation that took effect Wednesday.
The regulation requires rearview cameras and video displays on new models, a move aimed at preventing accidents in which pedestrians — often children — are run over because a driver can’t see them as they back their vehicles.
Congress passed a law in 2008 requiring regulators to enact measures requiring the adoption of technology to greatly improve rearview visibility.
After years of delays, the Department of Transportation announced the camera requirement in 2014, giving automakers several years to prepare.
Many higher-end models and mainstream vehicles with extra safety packages already have rearview cameras. But the technology will now be standard in even the cheapest of new cars.
