How many hours in a 24-hour period may drivers carrying explosives or other hazardous cargo drive?

The regulations governing the transportation of explosives and other hazardous materials dictate that drivers may operate their vehicles for a maximum of 8 hours within a 24-hour period. This limit is established to help ensure the safety of both the driver and the general public, as driving a vehicle carrying such dangerous cargo requires heightened focus and alertness. Limiting driving time helps reduce the risk of accidents that could result in catastrophic consequences due to the volatile nature of the materials being transported. Therefore, the choice indicating 8 hours is correct in the context of these safety regulations.
