A feature that was once a bonus on your car is now required for all vehicles in the U.S.
USA Today reports that a federal regulation took effect Wednesday, requiring rear-view cameras and video displays in all new passenger vehicles.
Congress passed the law in 2008, but automakers had several years to get ready for the change.
Rear-view cameras and video displays are already included on many higher end models and vehicles with extra safety packages. Now, they will be standard even on the cheapest of new cars.
The measure is intended to help drivers avoid accidents. More than 200 people are killed every year in backover crashes and more than 12,000 are injured.
