What is the maximum allowed variance in bumper height for passenger vehicles from the original equipment?

The maximum allowed variance in bumper height for passenger vehicles from the original equipment is indeed 3 inches. This regulation is designed to ensure that vehicles maintain a safe and standardized height to minimize the risk of damage during collisions and ensure compatibility with other vehicles on the road. Maintaining this height limit is crucial for vehicle safety standards, as large discrepancies in bumper height can lead to increased injury risks in the event of crashes, particularly for smaller vehicles or pedestrians.

While other options suggest smaller variances, they do not meet the safety and regulatory standards set forth. A variance of 3 inches strikes a balance between allowing for some modifications to vehicles while still adhering to the necessary safety protocols established by traffic laws.
