At what height will a light duty truck's bumper cause it to fail inspection due to suspension alterations?

A light-duty truck's bumper height is an important aspect of vehicle safety and compliance with state inspection standards. In New Hampshire, vehicles that have undergone suspension alterations must meet specific bumper height regulations to ensure safe operation on the road. The key metric for light-duty trucks is the maximum allowable bumper height.

When the bumper height exceeds 30 inches, it indicates that the vehicle's suspension may have been raised in a manner that compromises the vehicle's handling, safety, and structural integrity. Therefore, a truck with a bumper height of 30 inches or more will fail the inspection. This standard is in place to ensure that vehicles do not pose unnecessary risks to drivers, passengers, and other road users by maintaining appropriate vehicle dynamics and safety features.

Lower options, such as those around 16 inches and 20 inches, would not trigger a failure because they fall below the threshold for excessive modification. Similarly, 36 inches exceeds the limit but falls into the context of extreme modifications that would be automatically disqualified for safety concerns. Thus, the correct height that results in failure due to suspension alterations is 30 inches.
