The rule will require all vehicles under 10,000 pounds, including buses and trucks, manufactured on or after May 1, 2018, to come equipped with rear visibility technology that expands the field of view to enable the driver of a motor vehicle to detect areas behind the vehicle to reduce death and injury resulting from backover incidents. The field of view must include a 10-foot by 20-foot zone directly behind the vehicle. The system must also meet other requirements including image size, linger time, response time, durability, and deactivation.
