If a small hazmat leak is discovered, should the driver attempt to continue to a repair facility or terminal?

Correct answer

No — a leaking hazmat vehicle should not be driven; stop, secure the area, and get appropriate help (do not move the vehicle to 'fix it later')

  1. A Yes, drive to the nearest terminal regardless
  2. B No — a leaking hazmat vehicle should not be driven; stop, secure the area, and get appropriate help (do not move the vehicle to 'fix it later')
  3. C Yes, if it's only a small leak
  4. D Only drive at night

Why this is the answer

NO — a driver should NOT drive a LEAKING hazmat vehicle to a repair facility or terminal. CDL hazmat. A leak can worsen, spread contamination along the route, create fire/health/environmental hazards, and endanger the public. The correct actions: STOP safely; SECURE the area and keep people away (use ERG isolation distances); NOTIFY authorities (911 and required reporting); use the shipping papers/ERG to inform responders; do NOT attempt repairs or moving the vehicle beyond what's needed for immediate safety. 'I'll just drive it to get it fixed' is wrong and dangerous with a leaking hazmat load. Trained responders handle the leak. Knowing NOT to drive a leaking hazmat vehicle is a critical, commonly tested safety concept.
