Pneumatic-tired earth moving equipment whose maximum speed exceeds how many mph must be equipped with fenders?

The requirement for pneumatic-tired earth moving equipment to be equipped with fenders stems from safety regulations established to prevent accidents and injuries. When this type of equipment exceeds a maximum speed of 15 mph, the installation of fenders becomes necessary to shield wheels and tires from debris and to reduce the risk of materials being thrown from the machine while it is in operation.

This safety measure is crucial in construction sites where other workers may be present, as it helps minimize the chance of objects striking personnel or causing property damage. By mandating fenders for equipment that operates at higher speeds, the regulations ensure that proper safeguards are in place to protect those working near or with the machinery. Therefore, the threshold set at 15 mph reflects a balance between operational functionality and safety considerations in construction environments.
