What is the required front or rear impact collision withstand speed for a bumper according to federal regulations?

The required front or rear impact collision withstand speed for a bumper according to federal regulations is 2.5 MPH. This standard is established to ensure that vehicles are equipped with bumpers capable of absorbing minor collisions without sustaining significant damage. This requirement helps to minimize repair costs for vehicle owners and encourages manufacturers to design bumpers that can provide a degree of protection during low-speed impacts, which are the most common type of collisions. By mandating the 2.5 MPH threshold, the regulations aim to enhance overall vehicle safety and durability in everyday driving situations.
