DOT Inspections for Trucks & Trailers

RT Group performs annual FHWA DOT inspections for trucks and trailers in Zion, IL, minutes off I-94 — covering brakes, lighting, steering, suspension, tires, and required documentation, with fleet batch scheduling available.

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.
