If you need to placard a vehicle for hazardous materials, at least how many placards will you need?

Explanation:
Hazardous materials must be placarded on all four sides of a vehicle so the danger is clearly identified from every approach: front, rear, and both sides. That means a minimum of four placards—one on each side. If the load includes more than one hazard class, you add more placards (one for each class on each side), but the starting minimum is four. This ensures emergency responders and other drivers can quickly recognize the type of hazard no matter where they look.
