What is the maximum front and rear bumper height for passenger vehicles?

The maximum front and rear bumper height for passenger vehicles is set at 22 inches. This standard is established to ensure safety and performance during crashes, as well as to promote uniformity across different vehicle designs. The 22-inch limit helps minimize the risk of harm to pedestrians and drivers of smaller vehicles by facilitating better energy absorption and impact alignment during collisions. Maintaining this height standard is critical in the regulation of vehicle safety features and overall traffic safety on the roads. Additionally, aligning bumper heights can contribute to consistent vehicle interaction and reduce the risk of damage during low-speed collisions.
