What is the maximum bumper height for Class E and Class M vehicles?

The maximum bumper height for Class E and Class M vehicles is correctly identified as 28 inches. This regulation is in place to ensure that vehicles adhere to safety standards that promote uniformity in bumper height, which can help prevent damage to both vehicles in the event of a collision and enhance pedestrian safety.

Maintaining a specified bumper height is crucial for minimizing the risk of under-ride accidents, where smaller vehicles or pedestrians could get caught underneath larger vehicles in the event of a crash. The 28-inch limit ensures that the bumpers of these vehicle classes are sufficiently high to provide adequate protection while also maintaining functional design for driving conditions. Understanding these standards is essential for vehicle inspectors to ensure compliance.
