After years of delay, beginning May 1, 2018, all vehicles weighing less than 10 000 pounds, including buses and trucks, must be equipped with rear backup cameras to reduce death and injury from “backover” incidents (occurring when a vehicle backs up and strikes a person behind the vehicle). The 2018 start date, announced on March 31 by the National Highway Traffic Safety Administration (NHTSA), is 10 years after the passage of the Cameron Gulbransen Kids Transportation Safety Act requiring such cameras and 7 years after the measure was supposed to be implemented.
