Where must placards be placed on a vehicle carrying hazardous cargo?

Placards are essential for identifying the type of hazardous cargo being transported and ensuring safety during transportation. For vehicles carrying hazardous materials, the law requires placards to be displayed on the front, rear, and both sides of the vehicle. This comprehensive placement allows for easy visibility from multiple angles, enabling first responders and others to quickly identify potential hazards in the event of an accident or spill.

This widespread display of placards is crucial for public safety, as it communicates the risks associated with the cargo not just to those operating the vehicle, but to everyone around it, including emergency personnel. Each placard should be clearly visible and not obstructed by any other equipment or cargo on the vehicle. This requirement helps to ensure that all necessary precautions can be taken in case of an emergency involving hazardous materials.
