Arkansas CDL Permit Test - HazMat

Diamond-shaped signs called placards are placed on bulk packages and on the outside of vehicles to warn drivers and others of the presence of hazardous materials. It is the responsibility of the shipper to place the placards, and it is the responsibility of the driver to verify that the correct placards have been placed.

Always turn off your vehicle's engine before loading or unloading explosive materials. Never drop, throw, or roll packages containing explosives.

You should not smoke within 25 feet of a placarded cargo tank used to transport materials that are categorized as Class 3 (flammable liquids) or Division 2.1 (gases). Do not smoke or carry a lit cigar, pipe, or cigarette near a vehicle containing flammable or explosive materials.

You must have a CDL with a hazardous materials endorsement to operate a vehicle of any size to transport hazardous materials.

The shipper of hazardous materials is responsible for packaging, marking, and labeling the materials properly. It is a good idea for the driver to ensure the materials are properly labeled.

If your vehicle breaks down on the road while you are transporting explosive materials, you must warn other drivers. Put out warning signals like reflective triangles or electric lights if you are carrying Division 1.1, 1.2, or 1.3 explosives. Do the same if you are driving a tank used to transport Class 3 flammable liquids or Division 2.1 flammable gases, even if the tank is empty. If transporting flammable materials, do not use warning signals that could cause your cargo to catch fire.
