How to Handle a DOT Inspection: Driver's Checklist

DOT inspections happen without warning, and a failed inspection goes on your PSP report for three years. Being prepared takes 15 minutes of daily effort and can save your career.

Pre-Trip: Your Best Defense

A thorough daily pre-trip inspection catches 90% of items that fail DOT inspections. Check all lights (headlights, brake lights, turn signals, marker lights), tire condition and pressure, brake adjustment, air lines, mirrors, and windshield wipers. Document your pre-trip in your ELD — inspectors look for this. See our HOS compliance guide for logging requirements.

Documents You Must Have

CDL with correct endorsements, valid DOT medical card (carry a physical copy — not just digital), current registration, proof of insurance, HOS logs (last 8 days), annual vehicle inspection report, DVIR (last 24 hours), hazmat shipping papers (if applicable), and your TWIC card if entering port facilities.

The 6 Levels of DOT Inspection

Level I (Full Inspection): Everything — driver credentials, vehicle condition, cargo securement. Takes 45-60 minutes. This is the most common type.

Level II (Walk-Around): Driver credentials plus walk-around vehicle check. No under-vehicle inspection. Takes 15-30 minutes.

Level III (Driver Only): Credentials, license, medical card, HOS logs, seatbelt use, and substance abuse check.

Top Violation Categories

According to FMCSA, the most common violations are: HOS violations (30%), brake adjustment/components (24%), lights/reflectors (15%), tire condition (12%), and cargo securement (10%). Keeping your brakes adjusted and lights working eliminates nearly 40% of potential violations.

Your Rights During Inspection

You can request the inspector's credentials. You have the right to review the inspection report. You can note disagreements on the report. If placed out-of-service, you cannot drive until the violation is corrected — but you're entitled to a re-inspection at no charge.
