Displaying your us dot number sticker outside of your commercial is one of the most important things to do as a professional truck driver. Your USDOT number identifies your transportation/logistics business in the United States.
There are thousands of infrared cameras that their sole purpose is to read your USDOT number and other regulation numbers applicable to you. If you can see from the example below, these cameras can read your numbers in the middle of darkness, with glare, with low contrast, blurred numbers and in many font types.
Don’t be a dirty trucker and try to avoid displaying your USDOT number as this could lead to you being put out of service an a heavy fine.
