How often must you stop your vehicle to check dual tires when hauling hazardous materials?

When transporting hazardous materials, it is crucial to ensure that all vehicle components, including dual tires, are in good condition to prevent any incidents that could lead to spills or accidents. The regulation states that a driver is required to stop the vehicle and check the condition of dual tires after a specified period of time or distance traveled.

The correct interval is every 2 hours or every 100 miles. This requirement is designed to enhance safety during the transportation of hazardous materials, as dual tires can experience conditions that may lead to tire failure, jeopardizing the safe transport of dangerous goods. By stopping at these intervals, drivers can inspect the tire pressure, look for any signs of damage, and make sure that the tires are functioning properly, thereby reducing the risk of a tire-related incident.

Selecting intervals outside of 2 hours or 100 miles would not adequately meet regulatory requirements regarding safety checks when handling hazardous materials. For example, stopping more frequently than this could lead to unnecessary delays and may not be practical, while stopping less frequently could increase the risk of tire issues going unnoticed. Hence, the rationale behind this regulation emphasizes safety and preventative maintenance during the transportation of hazardous materials.
