How far must safety guards on a road tractor or truck be located from the surface of the highway?

The correct distance for safety guards on a road tractor or truck to be located from the surface of the highway is established to ensure adequate protection for pedestrians and other road users while minimizing the risk of damage during collisions. A distance of 8 inches is intended to effectively balance the need for safety with the practicality of vehicle design and operation on roadways.

Positioning the safety guards at this specified height allows them to function properly without being too high to lose effectiveness in preventing debris or objects from interfering with traffic or from harming individuals on foot. In this way, an 8-inch clearance adheres to safety regulations and best practices established in the industry for maintaining safer road conditions.
