Question

Pneumatic-tired earth moving equipment whose maximum speed exceeds 15 mph must:

a) Be equipped with an additional braking system.
b) Only operate during daylight hours.
c) Comply with noise level regulations.
d) Display a special warning sign.

Answer 1

Pneumatic-tired earth moving equipment exceeding 15 mph must be equipped with an additional braking system to maintain safety and control.

Step-by-step explanation:

For pneumatic-tired earth moving equipment with a maximum speed exceeding 15 mph, it is essential that the machinery is equipped with additional braking systems. This is to ensure the safety and control of the equipment during operation at higher speeds. Heavy-duty vehicles, such as those used in construction, often come equipped with specialized brake systems, which could include power brakes. Power brakes typically involve a motorized pump that assists in applying the necessary force to slow down or stop the vehicle efficiently. The reference to power brakes suggests a critical role in managing a vehicle's momentum, especially in scenarios that may not entirely rely on the aid of friction between the tires and the road, such as when navigating curves at ideal speed.

While other rules may apply, such as compliance with noise levels considering the occupational hazard for workers exposed to prolonged noise, or displaying warning signs for safety, the specific reference to the braking system is most pertinent to the operation of the equipment at higher speeds.
