Which of the following is a requirement for rubber-tired heavy equipment vehicles?

The requirement that rubber-tired heavy equipment vehicles must have fenders when exceeding 15 MPH is rooted in safety regulations designed to protect both the operator and bystanders. Fenders help contain materials and debris that may be dislodged from the tires while the vehicle is in motion, particularly at higher speeds. This is crucial when working in environments where such hazards could pose risks of injury or accidents to nearby workers or the public.

While other requirements may apply to heavy equipment, not all vehicles are mandated to be equipped with GPS, wider tires, or undergo daily inspections specifically due to speed. Regulatory focus often emphasizes ensuring that vehicles do not pose additional dangers as their operational speeds increase. Therefore, having fenders thus becomes a critical safety measure for vehicles operating at higher speeds, further justifying why this requirement is necessary.
