SUMMARY: To reduce the risk of devastating backover crashes involving vulnerable populations (including very young children) and to satisfy the mandate of the Cameron Gulbransen Kids Transportation Safety Act of 2007@ NHTSA is issuing this final rule to expand the required field of view for all passenger cars@ trucks@ multipurpose passenger vehicles@ buses@ and lowspeed vehicles with a gross vehicle weight of less than 10@000 pounds. The agency anticipates that today's final rule will significantly reduce backover crashes involving children@ persons with disabilities@ the elderly@ and other pedestrians who currently have the highest risk associated with backover crashes. Specifically@ today's final rule specifies an area behind the vehicle which must be visible to the driver when the vehicle is placed into reverse and other related performance requirements. The agency anticipates that@ in the near term@ vehicle manufacturers will use rearview video systems and in-vehicle visual displays to meet the requirements of this final rule.
