If you discover a leaking tire while hauling hazmat, you must:

• A. Continue to destination
• B. Stop at the nearest safe place and fix it
• C. Remove the wheel at the roadside
• D. Call the dispatcher and proceed slowly

Answer: (B)

When carrying hazmat, any tire issue is treated as an immediate safety hazard. A leaking tire can worsen quickly, and in a hazmat situation the consequences of a tire failure are even more serious, so the vehicle must be brought to a safe stop as soon as possible to assess and address the problem.

Stop at the nearest safe place to inspect the tire and fix it if you can do so safely. This keeps you, other road users, and the hazmat cargo out of danger and prevents the risk of a blowout or product release while in transit.

Continuing to the destination would leave you driving with a compromised tire, which isn’t safe or compliant. Removing a wheel at the roadside is hazardous and not an appropriate roadside repair, and merely telling the dispatcher and proceeding slowly doesn’t address the immediate risk. Stop, repair or replace the tire, and resume only when it’s safe to do so.
