What should drivers regularly check when handling hazardous materials?

When handling hazardous materials, it is crucial for drivers to regularly check the vehicle's condition and equipment. This is because the safe transport of hazardous materials relies heavily on the vehicle being in optimal working order. Regular inspections of the vehicle ensure that important systems, such as brakes, tires, lights, and safety equipment, are functioning properly. This reduces the risk of accidents and potential exposure to hazardous materials in the event of a malfunction.

While factors like weather conditions, arrival times, and load weight can be important in different contexts, they do not directly relate to the immediate operational safety of the vehicle itself. The condition of the vehicle and its safety equipment plays a pivotal role in preventing incidents that could lead to leaks, spills, or accidents, all of which are critical when transporting hazardous materials. Thus, maintaining an awareness of the vehicle's integrity is essential for the safety of the driver, other road users, and the environment.
