Where should placards indicating dangerous goods NOT be placed on transport trucks?
- The top ✓
- The front
- The rear
- The passenger side
Answer: A. The top
Dangerous goods placards should not be placed on the top of a transport truck.
Why this is the answer
The handbook describes the placards as appearing on the sides and on both ends of transport trucks, meaning the front and the rear. The top of the vehicle is not listed as a place where these placards go, so it is the location that does not apply. The same page also notes that if you work with dangerous goods, your employer must certify that you have had the right training, and you must carry that certificate while you haul them.
Why the other answers are wrong
- B. The front — The front is one of the two ends the handbook mentions, so placing a placard there is normal practice.
- C. The rear — The rear is the other end the handbook names, so a placard belongs there.
- D. The passenger side — The sides of the truck are listed as places where these placards appear, and the passenger side is one of those sides.
Remember it
Picture a truck on a highway: you spot the hazard sign from the side or from ahead or behind, never by looking at the roof.
