Under what conditions should fenders be required on vehicles?

Fenders are crucial for maintaining safety, particularly in environments where vehicles are in motion, such as construction sites. The requirement for fenders on vehicles is typically determined by the speed at which they operate. At speeds over 15 MPH, there is an increased risk of debris being kicked up by the tires, which can pose hazards to pedestrians, other vehicles, and the environment.

Fenders help to deflect or contain debris, ensuring that materials do not scatter and cause injuries or accidents as the vehicle moves. Additionally, the engineering and design standards for vehicles suggest that at speeds above this threshold, the potential for such hazards increases significantly, justifying the need for fenders to enhance operational safety.

Thus, the stipulation that fenders should be required when speeds exceed 15 MPH aligns with recognized safety protocols and regulations aimed at minimizing risks associated with vehicle operation on job sites.
