Request PDF ChecklistWhat Inspectors Check During DOT Inspection
DOT inspections are conducted according to standardized levels established by the Commercial Vehicle Safety Alliance (CVSA). Understanding these inspection levels helps you know what to expect and how to prepare.
Level I - North American Standard Inspection
The most comprehensive inspection. Includes examination of the driver (credentials, HOS, ELD) AND a complete vehicle inspection. Takes approximately 45-60 minutes. Inspectors check all safety systems, undercarriage, and documentation.
Level II - Walk-Around Driver/Vehicle Inspection
Similar to Level I but without going under the vehicle. Inspectors check all items visible from a walk-around plus driver credentials, ELD, and logbook. Most common inspection type at weigh stations.
Level III - Driver-Only Inspection
Focuses only on the driver. Examines CDL, medical card, HOS records, ELD data, and seatbelt use. Vehicle is not inspected unless obvious defects are observed. Quick inspection taking about 15-20 minutes.
Regardless of inspection level, drivers must always have their required documents readily accessible. Fumbling for paperwork creates a poor first impression and can lead to more thorough scrutiny. Keep all documents organized in one location in your cab.
ELD Logbook Inspection
Your ELD and logbook are among the first things inspectors examine. They want to verify you are operating within Hours of Service regulations and that your ELD is functioning properly and registered with FMCSA.
ELD Inspection Checklist
If your ELD has malfunctioned, you must have documentation showing you reported the malfunction to your carrier within 24 hours and have been maintaining paper logs. You have 8 days to repair or replace a malfunctioning ELD. Always carry paper log forms as backup.
Inspectors will also verify your HOS compliance by checking available hours. Common violations include driving over 11 hours, exceeding 14-hour window, violating 30-minute break requirement, and exceeding 60/70-hour limits. Know your hours before reaching inspection points.
Brake System Inspection
Brake violations are the leading cause of out-of-service orders during DOT inspections. Inspectors conduct thorough brake examinations, especially during Level I inspections. Understanding what they check helps you maintain your brakes properly.
Air Brake Checks
- Air compressor operation
- Air tank pressure (120-145 PSI)
- Low air pressure warning (55 PSI)
- Air leaks in lines and connections
- Slack adjuster adjustment
- Pushrod stroke measurement
Brake Component Checks
- Brake lining thickness (min 1/4 inch)
- Brake drum condition
- Brake hose and tubing
- Brake chamber condition
- ABS indicator light function
- Parking brake operation
Out-of-Service Criteria
If 20% or more of your brakes are defective, you will be placed out of service. For a typical 18-wheeler with 10 brake positions, having just 2 defective brakes triggers OOS status. Regular brake maintenance is essential.
Lights and Safety Equipment
Lighting violations are common and easily preventable. A complete walk-around before every trip helps catch burned-out bulbs and damaged lenses. Inspectors check all lighting systems and required safety equipment.
Required Lights (All Must Function)
Required Safety Equipment
Fire extinguishers must be properly mounted and accessible. Check the pressure gauge monthly and have the extinguisher professionally inspected annually. The inspection tag should show the most recent service date.
Pre-Trip Inspection Checklist
A thorough pre-trip inspection is your first line of defense against DOT violations. Federal regulations require drivers to conduct a pre-trip inspection before operating a CMV. Document your inspection and address any defects before driving.
Tractor Inspection
Coupling & Trailer
Tires & Wheels (All Positions)
Document your pre-trip inspection using your carrier's DVIR (Driver Vehicle Inspection Report) system. Note any defects discovered and do not operate the vehicle until safety-critical defects are corrected. Keep records of previous inspections accessible in your cab.
