US DOT Number

The U.S. DOT number is used to check the company’s safety records and compliance with regulations. The US DOT Number is overseen by The US Department of Transportation. US DOT implements the law while the Federal Motor Carrier Safety Authority (FMCSA) makes the law. FMCSA monitors and ensures compliance with regulations governing both safety (all carriers) and commerce (for-hire carriers). Companies may find they are subject to both registration requirements (USDOT Number and MC Number) or either one, separately.

Did you know the DOT is responsible for buses and airplanes too. Almost all transportation related stuff is regulated by the DOT. Transportation is a very important part of our lives. Safety is of the most important aspects of transportation. Keeping everyone safe on the road, in the air and on water is important.

  • USDOT Number Display Requirements

    After completing your trucks usdot number registration you will have to get cab door numbers put in on. These can be simple stickers that meet FMCSA requirements in terms of size and color. The FMCSA does not specifically state as to how large in size the letters and numbers on the stickers have to be in terms of height and width.

    The specific FMCSA USDOT number requirements is stated based on readability of the letters.
    Many truck drivers are at first confused by the FMSCA USDOT number size regulations, here is the exact legal requirement according to the FMCSA:

    Be readily legible, during daylight hours, from a distance of 50 feet (15.24 meters) while the CMV is stationary;

    Even though the USDOT number size requirements are not specifically some common sense must be used as to the minimum size requirements in terms of the height and width of the lettering in inches.

    The USDOT number size that is most ideal is approximately 2 inches tall.

    There are vendors all over the US, especially in major cites, that can produce the US DOT number decals. Some of the lettering can be plain and simple and some can be very fancy. Some decals have shiny metallic finishes and some are simple matte black. The final choice is up to the trucker. If you have a fancy rig with chrome and customization you will want the fancy lettering. If you have an “off dealer lot” tractor you will want standard lettering. In any case readability is the most important factor for the lettering.

    USDOT Number Display

    The usdot number location on truck is on the cab doors and/or the secondary location is just to the right of the door, when facing the cab door. On day cab types of tractors this space is not available.

    USDOT number placement is almost always on the cab (the tractor) door..
