DOT Inspections for Trucks & Trailers
What Gets Checked in an Annual FHWA Inspection
- Brake system function and adjustment (air and hydraulic)
- Steering and suspension components
- Tires, wheels, and rims
- Lighting and electrical systems
- Coupling devices and frame condition
- Required decals, documentation, and periodic inspection sticker
How Long It Takes
A standard annual inspection typically takes under an hour per unit when no repairs are needed; failed items get a straight quote to fix on the spot since our repair bays and inspection bay are on the same property.
What to Bring
Vehicle registration, prior inspection report (if available), and any maintenance records for recent brake or steering work.
Fleet Batch-Inspection Option
Fleets can schedule multiple units across staggered slots so trucks come in a few at a time rather than all at once — see our Fleet Service page for details.
Built for Drivers Who Can't Afford Downtime
Failed items can usually be repaired in the same bay, same day.
Inspectors familiar with both Illinois and Wisconsin requirements.
Bring in multiple units across staggered slots to minimize downtime.
Stage additional trucks and trailers in our secure yard while you wait.

“I’ve been to a lot of shops, and RT Group is one of the few that actually does what they say. Rolled in with an issue on my trailer — no lights, busted wire. They got me in quick, showed me exactly what was wrong, and had it fixed that same day.”
“Brought my Freightliner Cascadia to RT Group after an air leak and brake issues. The mechanics found the problem quickly, explained what needed to be repaired, and got the truck back on the road the same day. No guessing, no unnecessary work, no surprise charges.”
“Great people working. Very professional and do quality work. We came in for some electrical issues on the trailer after another road service made a big mess there. They found the problem and fixed it quickly. Highly recommend this place.”
