DOT Truck Inspections

What is a DOT inspection?

A DOT, inspection is a series of tests that check whether commercial motor vehicles are in good working condition. They are often surprised by roadside inspections carried out by state troopers or enforcers under the authority of the Federal Motor Carrier Safety Administration (FMCSA).

Have our certified technicians complete the annual DOT inspection for your fleet. Our highly trained team is knowledgeable about a wide range of commercial vehicles and the DOT inspection parameters. The items on the annual DOT truck Inspection checklist include the following:

  1. Battery
  2. Braking System
  3. Exhaust System
  4. Frame
  5. Lighting
  6. Steering Mechanisms
  7. Suspension
  8. Tires
  9. Trailer Bodies
  10. Wheels & Rims
  11. Windshield Wipers

We estimate each DOT inspection will take approximately an hour to complete. Ensuring all these systems are in tip-top condition will keep your commercial vehicle on the highway and serve your customers. The DOT truck inspection checklist is essential for safety because underlying conditions may be developing. Our inspection team can spot these potential issues during the inspection and set up a replacement plan for the part or system. We recommend scheduling your DOT inspection well before the yearly deadline, that way, we can find a convenient time for your company and ensure it gets completed before the deadline. 

Maryland law requires that every registered truck over 10,000 pounds, truck tractor, and bus operated on public roads, unless specifically exempt*, must display either a USDOT Number or a Maryland-issued motor carrier identification number. If you are a motor carrier who is not required to have a USDOT Number because your vehicles do not leave Maryland and you do not handle interstate cargo, you must obtain a Maryland identification number (MD DOT #) and display it on your trucks, truck tractors, and buses.

Motor carriers that are interstate or intrastate must apply for a USDOT Number from the Federal Motor Carrier Safety Administration (FMCSA).

Applicants may apply online at

USDOT Numbers and MD DOT Numbers must be displayed in compliance with Federal Motor Carrier Safety Regulations (FMCSR) part §391.21. Motor carriers that are not in compliance are subject to fines.

*The following vehicles, if only operated intrastate, are exempt: Farm trucks, farm truck tractors, farm-area motor vehicles, emergency vehicles, vehicles primarily transporting money or commercial paper, vehicles owned or operated by the State or local government, and vehicles within 15 days of their purchase.
