Your Rights During a Roadside Inspection
What to expect during a CVSA roadside inspection, what inspectors can and cannot do, and how to challenge violations you believe are incorrect.
A. What inspectors can and cannot do
FMCSA-certified inspectors have the authority to stop and inspect commercial motor vehicles for compliance with federal safety regulations. During an inspection, the inspector can:
- Examine your driver's license, medical certificate, and record of duty status
- Inspect the vehicle's mechanical condition including brakes, tires, lights, and coupling devices
- Check cargo securement
- Verify hazmat placarding and shipping papers (if applicable)
- Place the vehicle or driver out of service for safety violations
Inspectors may not search personal belongings or the sleeper berth without consent or probable cause. They cannot require you to submit to a drug or alcohol test unless there is reasonable suspicion or the inspection follows a qualifying accident.
B. Inspection levels
The Commercial Vehicle Safety Alliance (CVSA) defines six levels of inspection:
Level I — Full Inspection
Complete examination of both driver and vehicle. Includes everything under the vehicle (brakes, suspension, frame) and all driver credentials and records.
Level II — Walk-Around Inspection
Driver and vehicle examination without going under the vehicle. Covers all items visible from a walk-around plus driver credentials.
Level III — Driver-Only Inspection
Examination of driver credentials only: license, medical certificate, hours of service records, seat belt use, and substance use (if applicable).
Level IV — Special Inspection
One-time examination of a specific item, often conducted as part of a study or safety initiative. Not a pass/fail inspection.
Level V — Vehicle-Only Inspection
Vehicle inspection conducted without the driver present, typically at a carrier's facility or terminal.
Level VI — Enhanced NAS Inspection
For select radiological shipments only. Includes Level I inspection plus additional radiological-specific requirements.
C. Your right to observe the inspection
You have the right to be present and observe any part of the vehicle inspection. You may ask the inspector to explain what they are checking and why. If you are unsure about a violation being written, you may ask the inspector to show you the specific condition they are citing. Being courteous and cooperative does not mean you agree with every finding — you can dispute violations later through the DataQs process.
D. Out-of-service criteria
An out-of-service (OOS) order means the vehicle or driver cannot continue operating until the cited condition is corrected. Common triggers include:
- Brake system defects (e.g., inoperative brakes on 20% or more of the braking system)
- Tire defects (flat, tread separation, exposed cord on steer tires)
- Coupling device failures
- HOS violations (driving beyond allowable limits)
- Expired or invalid medical certificate
- Suspended or revoked CDL
- Drug or alcohol violations
The full OOS criteria are published annually by CVSA and run over 100 pages. Violations that do not meet OOS thresholds are still recorded on the inspection report and affect the carrier's safety record.
E. How to dispute violations (DataQs process)
If you believe a violation was recorded in error, you can file a Request for Data Review (RDR) through FMCSA's DataQs system. DataQs is the formal process for challenging inspection violations, crash records, and other data that appears in the FMCSA Safety Measurement System.
To file a challenge, create an account at dataqs.fmcsa.dot.gov, select the type of record you are disputing, and provide supporting documentation. The state that conducted the inspection reviews the request and makes a determination. Common supporting documents include repair receipts, photographs, calibration records, and alternative evidence.
F. Recording the inspection
There is no federal law prohibiting you from recording a roadside inspection with a camera or smartphone, though some states have specific laws regarding audio recording and consent. If you choose to record, do so from a reasonable distance without interfering with the inspection. Let the inspector know you are recording. Your recording may serve as evidence if you later dispute a violation through DataQs.
G. Post-inspection: reviewing your report
After the inspection, the inspector will provide you with a copy of the inspection report (Driver/Vehicle Examination Report). Review it carefully before signing. Your signature acknowledges receipt of the report, not agreement with the findings. If violations were found that require repair, you typically have 15 days to have the vehicle repaired and submit certification of the repairs to the state that conducted the inspection.
H. Filing a DataQs challenge
The DataQs process is straightforward but requires attention to detail:
- Register at dataqs.fmcsa.dot.gov
- Select “Request a Data Review” and choose the record type (inspection, crash, etc.)
- Enter the inspection report number and your USDOT number
- Describe the specific violation(s) you are disputing and why
- Upload supporting documentation (photos, receipts, calibration records)
- Submit the request — you will receive a confirmation number
- The reviewing state typically responds within 60 to 90 days
If the state agrees the data is incorrect, the record is modified or removed. If the state disagrees, you may file an appeal or request an arbitration review.
