You are going to be hauling hazardous materials over a route you do not know well. When should you check the route and the permits needed for the trip?
Answer: B
Before starting the trip
Local and state regulations for the transportation of hazardous materials will vary. If a route is planned through an area where you are unfamiliar with the regulations it is the driver's responsibility to check the laws for restrictions prior to beginning the trip.

All choices
- AWhile you are still on a part of the route that you know.
- BBefore starting the trip

Why the other answers are wrong
A. While you are still on a part of the route that you know.
Choice A is wrong because route and permit checks must be done before starting the trip, not while already on the route.
C. Within 24 hours of the end of the trip.
Choice C is wrong because checking permits within 24 hours after the trip is too late and does not comply with regulations.
