After starting the trip
During the trip
Before starting the trip
Only if stopped by authorities

The correct answer is: Before starting the trip

A driver should check the route and permits needed for transporting hazardous materials before starting the trip to ensure compliance with safety regulations and legal requirements. This proactive step is essential for identifying potential hazards along the route, such as restricted areas, road closures, or regulations specific to the transportation of hazardous materials. By preparing in advance, the driver can plan accordingly, ensuring that they have the correct permits and are aware of any special procedures or precautions necessary for the transport. Checking the route beforehand allows the driver to make informed decisions that enhance safety for themselves, other road users, and the environment. It also facilitates avoiding unexpected delays or legal issues that could arise if the proper permits are not in place. Making these checks at the start of or during the trip may lead to complications, such as being forced to reroute or deal with authorities while on the road, which could pose safety risks and logistical challenges.
