  1. AEnsure the vehicle's air conditioning system is fully functional.
  2. BCheck that all placards are correctly displayed and legible.

  4. DConfirm that the vehicle's entertainment system is working.
Show answer & explanation

Correct answer: B. Check that all placards are correctly displayed and legible.

During a pre-trip inspection of a placarded vehicle, the driver has specific responsibilities regarding the hazardous materials cargo, including verifying that all required placards are present, correctly displayed, and clearly legible, as they communicate the hazard to others.

Why the other options are wrong

  • A. While important for driver comfort, the AC system is not a specific hazmat cargo safety check.
  • C. Tire inspection is a general pre-trip requirement for all commercial vehicles, not specific to hazmat cargo itself.
  • D. The entertainment system is irrelevant to the safe transportation of hazardous materials.

HazMat Pre-Trip Inspection

A driver transporting hazardous materials must perform a thorough pre-trip inspection, including specific checks related to the hazardous cargo such as placards, shipping papers, and securement.

  • Verify placards are correctly displayed and legible.
  • Ensure shipping papers are present and accessible.
  • Check that cargo is properly secured and packaging is intact.
  • Inspect for leaks or damage to containers/tanks.

Memory trick: Before you roll, hazmat checks make you whole: placards, papers, and no holes!
