Hazardous materials placards are four regulated signs on the outside of the vehicle that identify the hazard class of the cargo for those who need to know, such as emergency service personnel or those who load and unload cargo.
B So hazardous materials won't be mixed with food
C To warn other drivers to stay away from your vehicle
