Colorado CDL Permit Test - HazMat

Many products classed as poison are also flammable. Take the appropriate precautions if you think your cargo may be flammable.

You must take and pass the written English version of the HazMat knowledge test and be cleared through a federal background check before every renewal of your CDL.

If the words "Inhalation Hazard" appear on a package or its shipping paper, the "Poison Inhalation Hazard" or "Poison Gas" placards, as appropriate, must be displayed.

Shipping papers for hazardous materials should always be easily accessible. When a driver is not in their vehicle, hazardous materials' shipping papers should be left on the driver's seat.

The person in charge of loading or unloading a hazardous materials cargo tank must ensure that a qualified person is always supervising the process. The supervisor must be alert; have a clear view of the tank; be within 25 feet of the tank; know the hazards of the involved materials; know the procedures to follow in the case of an emergency; and be authorized to and capable of moving the tank.

The third column of the Hazardous Materials Table lists items' hazard classes and divisions. Drivers should never transport a material that is marked by the word "Forbidden."
