What procedure must be followed for examining tires on a CMV transporting hazardous materials?

The correct choice indicates that the examination of tires on a commercial motor vehicle (CMV) transporting hazardous materials must be performed every 2 hours or every 100 miles. This specific requirement is established to ensure the safety of the vehicle while transporting hazardous materials, as it is crucial to regularly check the condition of the tires. Tires are a critical element of vehicle safety, particularly when transporting potentially dangerous substances, and regular inspection ensures that issues such as under-inflation, damage, or wear are detected promptly, which can help prevent accidents.

Maintaining a short interval for inspections helps in promptly addressing any potential tire issues that could lead to catastrophic failures, especially considering the additional risks associated with hazardous materials. This protocol underscores the importance of proactive safety measures in hazardous material transportation, where both the driver and the public's safety could be significantly impacted by tire integrity.
