Driver (CDL) - Vehicle Identification

Every commercial motor vehicle transporting hazardous materials operated by a motor carrier in interstate commerce must be marked on both sides of the vehicles with the following:

• The motor carrier's name or trade name
• The motor carrier's identification number, preceded by "US DOT"
• The size, shape, and color marking must be in letters that contrast sharply in color with the background on which the letters are placed
• The lettering must be legible during daylight hours, from a distance of 50 feet

The Motor Carrier Identification Report (MCS-150) is a one-page form that must be filed with the FMCSA by all motor carriers in interstate commerce. In place of the MCS-150, carriers offering hazardous materials must file the MCS-150B "Combined Motor Carrier Identification Report and HM Report Application." This way, certain carriers of hazardous materials can receive an FMCSA Hazardous Materials Safety Permit.
