Do I need a U.S. DOT Number?

​A. Louisiana recently became a PRISM state and now requires anyone who purchases an apportioned plate to have a U.S. DOT number. The cab card is bar coded with the U.S. DOT number belonging to the motor carrier responsible for safety and/or the registrant.

Owner/operators who do not have their own operating authority and buy their own plates will need a “Registrant’s” U.S. DOT number. A “registrant” U.S. DOT number is for registration purposes only and does not provide the owner/operator with any type of operating authority. The “registrant’s” U.S. DOT number should not, under any circumstances, be displayed on the side of the truck/tractor. In addition, the owner/operator must provide the U.S. DOT number for the motor carrier/company to whom the vehicle is leased. Updated copies of the MCS-150 must be submitted for the owner/operator and the motor carrier responsible for safety. If the motor carrier has filed updated MCS-150 data within the prescribed twelve month period, only the U.S. DOT number and FEIN of the motor carrier must be provided.

Motor Carriers, who have not obtained a U.S. DOT Number, must complete both a MCS-150 and MCS-150A form to apply for their U.S. DOT Number. The LA IRP Issuance Office will be able to assist in the issuance of their number or they may contact the U. S. Department of Transportation for assistance. The Motor Carrier is required to have a U.S. DOT Number prior to operation.

The information contained in the MCS-150 form must be updated annually. You can update your information on-line at (http://www.safer.fmcsa.dot.gov). Click on "FMCSA Registration & Updates" and follow the instructions. A MCS-150 will be included in the IRP Renewal packet and should be returned with the completed renewal packet.

Effective January 1, 2005, motor carriers who transport certain hazardous materials, in interstate, intrastate and foreign commerce are required by FMCSA to have a HM Safety Permit. You can obtain a list of the hazardous materials requiring a HM Safety Permit by contacting the Federal Motor Carrier Safety Administration or on-line at the FMCSA website: (http://www.safer.fmcsa.dot.gov). Click on "FMCSA Registration & Updates" for the list of hazardous materials.

If you are a carrier transporting hazardous materials of the type and quantity requiring a permit, as defined under the Federal Motor Carrier Safety Administration’s new HM Permitting Regulations, you must file a MCS-150B with the Federal Motor Carrier Safety Administration. The MCS-150B form is available on the FMCSA website: (http://www.safer.fmcsa.dot.gov). Click on "FMCSA Registration & Updates". If you do not have internet access, you can contact the Federal Motor Carrier Safety Administration of the U. S. Department of Transportation to obtain a MCS-150B form .
