CDL · Hazardous materials
You have been assigned a hazardous materials load that must travel on roads you are not familiar with. At what point should you review the route and obtain any permits it requires?
Correct answer: Before you leave on the trip.
Answer options
- AOnce you are driving but still on roads you know
- BWithin 24 hours after the trip ends
- CBefore you leave on the trip Correct
Why
Some roads, bridges, and tunnels are closed to placarded vehicles, and some areas require permits for hazardous loads, so the route must be planned and the paperwork secured before departure. Finding a restriction partway through the trip can leave you with no legal way to continue.
