Each person or shipper who offers a motor carrier a Hazardous Material for transportation by Highway SHALL provide the required placards to the motor carrier.  The placards must be offered at the same time or prior to the transportation of the Hazardous Material. However the placards do not have to be offered by the shipper if the transport vehicle already has the placards required for the transport.

Once the motor carrier has the placards to transport a Hazardous Material, they must be properly affixed to the transport vehicle. The vehicle can not travel by Highway unless the requird placards are properly displayed.
