The useful answer
Where do USDOT markings go?
For commercial motor vehicles covered by the federal marking rule, the required carrier name and USDOT number are marked on both sides of the self-propelled commercial motor vehicle. The markings must remain readily legible in daylight from 50 feet while stationary.
The driver and passenger sides should each have a suitable clear surface. A door is common, but the rule is about the sides of the power unit and the required visibility, not a universal door-panel coordinate.

Test the proposed location
Stand back from each side of the parked truck and check whether the markings would remain visible and legible. Keep the letters clear of distracting graphics, hardware, and frequent obstructions. For a combined logo and permit design, prioritize the required wording and number.
Read the FMCSA marking guidance before finalizing your layout.
