When are you required to inspect the tires on a vehicle placarded with hazardous materials?

You are required to inspect the tires on a vehicle placarded with hazardous materials at the start of each trip. This inspection is crucial because the condition of tires directly influences the safety and stability of the vehicle, especially when transporting hazardous materials. Proper tire condition helps prevent accidents that could lead to the release of these materials, which could pose significant hazards to public safety and the environment.

Conducting this inspection as part of your trip preparation allows you to identify any potential issues—such as cuts, bulges, or insufficient tread—that might compromise the vehicle’s performance. Routine inspections help ensure compliance with regulations and contribute to road safety. Other options, like monthly inspections or inspections only during annual checks, do not focus sufficiently on the critical safety requirement of checking tires before each trip involving hazardous materials transportation. Regular inspections at fuel stops tend to concentrate on refueling and may not cover the extensive checks needed for tires.
