What must be done if a placard falls off during transport?

If a placard falls off during transport, it is essential to stop and replace it. Placards serve as crucial visual indicators of the materials being transported, particularly hazardous materials, and they inform others on the road and emergency responders of potential dangers. Proper signage is mandated by regulations to ensure safety and compliance during transportation.

When a placard is missing, it may lead to misunderstandings about the type of cargo being transported. This could pose risks to public safety, particularly in emergency situations where responders need to know what hazardous materials may be present. Thus, addressing the issue promptly by stopping to replace the lost placard is necessary to maintain safety compliance and clear communication about the vehicle's contents.
