49 CFR § 396.17 — Periodic inspection
49 CFR — Transportation · FMCSA / DOT
49 CFR 396.17 is the federal annual inspection — the formal, comprehensive inspection every CMV must pass at least once every 12 months. Performed by a qualified inspector (49 CFR 396.19) following Appendix G procedures. Covers every safety-critical component. The inspection report must be retained for 14 months. A current inspection report (or copy) must typically be available in the vehicle. Many states have federally-recognized state-mandated inspection programs that satisfy 49 CFR 396.17 — check your state for the substitute program. An expired annual inspection results in immediate out-of-service at any roadside inspection.
Regulation summary
Every CMV must be inspected at least once every 12 months. The periodic (annual) inspection must be performed by a qualified inspector per 49 CFR 396.19, using procedures equivalent to those in Appendix G to Part 396 or a federally-recognized state inspection program. The inspection covers all components specified in Appendix G: brake system, coupling devices, exhaust system, fuel system, lighting devices and reflectors, safe loading, steering mechanism, suspension, frame, tires, wheels/rims/hubs, windshield wipers, rear vision mirrors, and emergency exits (for passenger-carrying vehicles). The inspection report must be retained for 14 months from the date of inspection.
Who must comply
Every motor carrier operating CMVs subject to FMCSA jurisdiction. The 12-month inspection cadence applies to every CMV — trucks, trailers, buses. Owner-operators must arrange annual inspections for their own equipment. Leased equipment under the carrier's control must also be inspected.
What happens if violated
Civil monetary penalties: $1,100 to $16,550 per violation. An expired annual inspection at roadside = immediate out-of-service of the vehicle. CSA Vehicle Maintenance BASIC severely affected. Carriers operating with expired annual inspections across the fleet face cascading violations and likely Compliance Review with safety rating downgrade.
Implementation checklist
- Schedule annual inspection for each CMV before the 12-month deadline.
- Use a qualified inspector per 49 CFR 396.19 — verify credentials.
- Inspect every Appendix G component; document pass/fail per component.
- Issue/retain the inspection report (or sticker) for 14 months minimum.
- Place a copy of the current inspection report in the vehicle for roadside production.
- Track inspection due dates fleet-wide with 60/30/14-day alerts.
- For federally-recognized state programs, retain the state inspection report.
- Audit fleet inspection currency quarterly.
Common misinterpretations
- Misinterpretation: 'My DVIRs cover this.' Reality: DVIRs (49 CFR 396.11) are daily driver inspections. 49 CFR 396.17 is a separate FORMAL annual inspection by a qualified inspector covering Appendix G's full component list. Both are required.
- Misinterpretation: 'Any mechanic can do the annual inspection.' Reality: Only a qualified inspector per 49 CFR 396.19 can perform it. Qualifications include: previous training and experience, certification by a state inspection program, or other equivalent training.
- Misinterpretation: 'A current state safety inspection sticker satisfies 49 CFR 396.17.' Reality: Some state programs are federally-recognized as equivalent (check FMCSA's list); others are not. A state sticker alone is not automatic federal compliance — verify your state's program status.
Frequently asked questions
How often is the federal annual inspection required?
At least once every 12 months per 49 CFR 396.17(a). The exact anniversary date is at the carrier's discretion — many fleets inspect on a rolling schedule throughout the year to spread workload.
Who can perform the federal annual inspection?
A qualified inspector per 49 CFR 396.19. Qualifications include previous training and experience, state inspection program certification, or other equivalent training. The carrier's own mechanics can qualify if they meet 396.19 standards.
How long must the inspection report be retained?
14 months from the date of inspection per 49 CFR 396.21. A current report (or copy) typically must be available in the vehicle for roadside production.
Does a state safety inspection satisfy 49 CFR 396.17?
Only if the state program is federally-recognized as equivalent. FMCSA maintains a list of approved state programs. Many state inspection programs (CVSA-aligned) are recognized; standard private-vehicle state safety inspections are typically not.
What's inspected during the annual inspection?
Per Appendix G to Part 396: brake system, coupling devices, exhaust system, fuel system, lighting devices and reflectors, safe loading components, steering mechanism, suspension, frame, tires, wheels/rims/hubs, windshield wipers, rear vision mirrors, and (for passenger-carrying) emergency exits. Every safety-critical component is checked.
What happens if a CMV operates with an expired annual inspection?
Immediate out-of-service at roadside. Vehicle cannot move until a current inspection is completed. Carrier faces $1,100-$16,550 penalty. CSA Vehicle Maintenance BASIC points assessed.
