Every hour Every five hours Every two hours or 100 miles Every four hours

Correct Answer:

Every two hours or 100 miles

Explanation:

When transporting hazardous materials, it is essential for safety and compliance to check the tires every two hours or every 100 miles. This requirement is in place to ensure that the vehicle is in safe operating condition, particularly because hazardous materials can pose significant risks in the event of an accident. Regular tire checks help prevent blowouts, ensure proper inflation, and assess tread wear, all of which contribute to the overall safety of the journey. Frequent tire inspections are particularly critical for vehicles carrying hazardous loads due to the potential catastrophic consequences of tire failure while transporting dangerous materials.
