When parked, is it acceptable for a driver to be asleep in a vehicle containing explosive materials?

The correct choice emphasizes the critical importance of safety regulations surrounding vehicles transporting hazardous materials, particularly explosives. When it comes to dangerous goods like explosives, strict protocols are in place to minimize risks associated with their handling and transport.

Having a driver asleep in a vehicle containing explosive materials poses significant safety risks. If a driver is incapacitated, they cannot respond to emergencies, such as a fire, accident, or unauthorized personnel approaching the vehicle. Regulations often mandate that a vehicle transporting hazardous materials must have someone present and vigilant to ensure immediate action can be taken in case of an emergency.

Other choices suggest scenarios under which a driver might safely sleep in the vehicle, such as the engine being off, the nap being short, or another person being awake. However, these scenarios do not align with safety standards and regulations designed to prevent accidents involving explosives. Hence, the prohibition on sleeping in such a vehicle stands firm as a measure to protect both the driver and the surrounding public from potential hazards.
