Introduction
A decal on a cab door or trailer is the first thing an officer sees. It signals that someone inspected the unit. It does not replace the inspection report, and it does not excuse you from maintaining the vehicle.
This guide is for fleet owners, drivers, maintenance managers, and operators of trucks and trailers. Federal rules set the baseline. States can add their own sticker, placement, or paperwork requirements on top.
Below, we cover what the sticker means, what records must back it up, how annual inspections differ from roadside CVSA inspections, and how to handle replacement decals.
In calendar 2023, FMCSA reported 3,013,478 roadside inspections, and 19.6% produced at least one out-of-service violation.
Key Takeaways
- The annual inspection, the report, and the decal are related but not interchangeable.
- A current decal doesn't exempt a unit from roadside inspection or predict a pass.
- Match every decal and record to the right VIN or unit number.
- Confirm rules with 49 CFR, FMCSA, CVSA, and your state.
What an Annual DOT Inspection Sticker Means
What is an annual DOT inspection?
Federally, it's called a periodic inspection. Under 49 CFR 396.17, each covered commercial motor vehicle must pass one at least every 12 months. That includes every unit in a combination: tractor, semitrailer, full trailer, and converter dolly.
The inspection criteria live in Appendix A to Part 396 (Minimum Periodic Inspection Standards). Older material calls this Appendix G, so check the current eCFR.
Inspectors must be qualified under 396.19. They need to understand Part 393 and Appendix A methods, and hold a training certificate or at least one year of combined training and experience.
The inspection is the event. The report and any decal are the evidence.
Practical steps for verifying your cycle:
- Confirm the inspection date on the report, not just the sticker.
- Set the renewal reminder before the 12-month mark.
- Check whether your state displays expiration information differently.
Why the sticker is only one piece of compliance evidence
Here's the part many operators miss: a decal isn't federally mandatory. Section 396.17(c) allows proof on the vehicle to be either the 396.21(a) inspection report or other documentation, such as a decal, containing the required information.
An unexpired sticker also says nothing about a vehicle's condition today. A brake can fail in month four. A Level I or II roadside inspection will find it regardless.
Several markings can look alike on a truck, and they aren't the same:
| Marking | What it is |
|---|---|
| Annual inspection report or decal | Evidence of the Part 396 periodic inspection |
| CVSA decal | Roadside inspection credential, not a substitute for the annual inspection |
| State safety sticker | State-program evidence; counts federally only if the program meets equivalency criteria |
| IRP apportioned plate or cab card | Registration, not inspection proof |
FMCSA removed its former interpretation that a clean CVSA Level I or V inspection could satisfy the periodic requirement, because roadside inspections don't examine every annual-inspection item.
When a sticker creates a compliance concern
Trouble starts with a decal that is expired, missing, damaged, illegible, altered, duplicated, or assigned to a different unit.
Don't fix any of these yourself. Never change a date, reuse a decal, or move one from another unit. Contact the qualified inspector or issuing authority for a correction or replacement.
Section 396.17(c) bars use of a vehicle without a passed inspection in the prior 12 months and the required proof aboard. Penalties depend on federal and state rules, the report you can produce, and the circumstances of the stop.
Section 390.37 allows civil or criminal penalties for violations of the subchapter, but no fixed sticker-specific fine applies. Beware of anyone quoting one.
What the Sticker and Supporting Documentation Must Show
What belongs on a decal
Under 396.17(c), alternate documentation such as a decal must show:
- The inspection date
- Name and address of the carrier, inspection entity, or whoever keeps the report
- A unique vehicle identifier, if not clearly marked on the vehicle
- Certification that the vehicle passed
Federal rules don't set color, size, stock, or layout. States and programs may. Don't assume a generic design satisfies every jurisdiction.
The decal's details should match the official report: VIN, unit number, and tractor or trailer ID where applicable.
What the carrier should keep
The 396.21(a) report identifies the inspector, the carrier or inspection entity, the date, and the vehicle. It lists components inspected and results, including failures, and certifies accuracy.
Carriers must:
- Keep the original or a copy for 14 months from the report date, where the vehicle is housed or maintained
- Make it available to authorized officials on demand
- Carry compliant proof on the vehicle
Electronic records are allowed under 390.32 if they stay accurate and reproducible. The requirement to carry proof on the vehicle under 396.17 still applies.
Organize files by unit. A driver or fleet manager should be able to confirm the inspection date, inspector, defects, repairs, and next renewal in seconds.
Truck and trailer documentation
Inspection coverage runs vehicle by vehicle. Check the tractor and each trailer separately, and confirm each has correct evidence aboard.
A common error: a report or decal filed against the wrong trailer after a swap, with similar unit numbers. The paperwork looks fine until an officer compares it to the VIN. Federal rules don't require one physical sticker per unit if compliant documentation identifies what's covered, but your state may differ.
Missing, damaged, or incorrect decals
Federal rules don't spell out a replacement process, so work through it methodically:
- Treat the unit's status as unconfirmed until verified.
- Contact the qualified inspector or issuing authority.
- Request valid replacement evidence.
- Update your fleet record.
- Confirm whether the unit may operate in the meantime. The original report is an allowed form of proof, so keep it onboard.
Document the request in writing and retain the original report unaltered.
Annual Inspections Versus Roadside DOT and CVSA Inspections
Annual inspection compared with a roadside inspection
| Annual inspection | Roadside inspection | |
|---|---|---|
| Purpose | Scheduled compliance and maintenance check | Enforcement examination |
| Timing | At least every 12 months | Any time during operation |
| Output | Report, optional decal | Inspection report, possible violations or OOS order |
A current annual decal doesn't exempt you from roadside inspection under 396.9, driver-document checks, cargo-securement checks, or out-of-service criteria. Defects that develop after the annual inspection will surface, so pre-trip inspections and preventive maintenance still matter.
The different inspection levels
CVSA's inspection levels cover:
- Level I: driver and vehicle
- Level II: walk-around driver and vehicle
- Level III: driver credentials and administrative
- Level IV: special, usually one-time examination of an item
- Level V: vehicle only
- Level VI: transuranic waste and certain radioactive materials
- Level VII: jurisdiction-mandated; no CVSA decal
- Level VIII: electronic inspection while moving
The annual inspection isn't a ninth level. It's a separate obligation with its own records. A Level I or V inspection with no critical violations may earn a CVSA decal, valid for the month issued plus two months.
What happens during a CVSA inspection
A typical CVSA inspection follows this sequence:
- Selection or stop
- Document review
- Driver and/or vehicle examination
- Defect identification and violation classification
- Inspection report Exact procedures and out-of-service criteria come from CVSA. The 2026 criteria took effect April 1, 2026.
An annual-inspection paperwork problem can become one part of a wider review, though it doesn't automatically escalate.
For scale, CVSA's 2025 International Roadcheck logged 56,178 inspections with a vehicle OOS rate of 18.1%. Brakes were the top vehicle violation at 24.4% of vehicle OOS violations.
FHWA and other terminology
You'll hear "FHWA inspection" in the field. FMCSA was established January 1, 2000 and took over motor-carrier safety functions once handled by FHWA. Current regulation uses "periodic inspection," and official sources don't define "FHWA inspection" as a separate current category.
FHWA, FMCSA, DOT, and CVSA aren't interchangeable. Ask your state or inspection provider what terminology they use.
Preparing for an Annual or Roadside Inspection
Vehicle condition checklist
FMCSR Part 396 Appendix A covers these categories:
- Brakes and coupling devices
- Exhaust and fuel systems
- Lighting and reflectors
- Steering, suspension, and frame
- Tires, wheels, and rims
- Windshield glazing and wipers
- Safe loading and rear impact guard
- Motorcoach seats, where applicable
Also check cargo securement and emergency equipment against your configuration. Document defects, complete repairs, and verify them before dispatch.
Driver and fleet documentation
Keep the following current and reachable:
- Annual inspection report and decal
- Registration and insurance
- Driver credentials and medical documentation
- Hours-of-service records
A unit-level file or fleet calendar can track inspection dates, report locations, decal condition, repairs, and renewals.
Don't treat daily checks as the annual inspection. A DVIR is a post-trip report under 396.11, retained for three months. Before driving, the driver must be satisfied the vehicle is safe under 396.13. Neither replaces the periodic inspection.
After the inspection
- Review the completed report.
- Log defects and corrective actions.
- Photograph the installed decal.
- Store records for the required retention periods.
Maintenance records are kept for one year, and six months after the vehicle leaves your control.
If a vehicle fails, 396.17(c) bars its use until it passes and proof is aboard. After a roadside OOS order, don't operate until repairs are done.
The driver delivers the report to the carrier's next terminal. The carrier certifies correction within 15 days and keeps the report for 12 months.
Ordering, Replacing, and Applying Inspection Decals
Selecting a decal production partner
Confirm these before ordering:
- Required dimensions, colors, and printed fields
- Unit or serial information
- Adhesive compatibility and surface type
- Weather exposure and abrasion resistance
- Legibility from the expected viewing distance
Proof every decal for vehicle identifier, inspection date, expiration, issuing party, and any required state wording. A graphics provider can print a durable decal. It cannot perform the inspection, certify the vehicle, or substitute for official authority.
Replacement and fleet-order workflow
- Keep an approved artwork file.
- Collect unit-specific data.
- Verify variable data against the report.
- Order a small proof when needed.
- Deliver each decal to the correct vehicle.
Reduce mix-ups with unit-specific packaging, installation records, and a central log of issued and applied decals.

Frequently Asked Questions
What are the steps involved in the CVSA inspection procedure?
A stop or selection, document review, driver and/or vehicle examination, defect classification, then the inspection report. Check current CVSA guidance for exact procedures.
What are the different levels of DOT inspections?
Levels I, II, and III are the most common: driver and vehicle, walk-around, and credentials. Levels IV through VIII cover special, vehicle-only, hazmat, jurisdictional, and electronic inspections.
How long are CVSA decals valid for?
A CVSA decal is valid for the month issued plus two months. It's separate from the annual DOT sticker, so verify current CVSA eligibility rules.
Can you drive if your inspection sticker is expired?
Section 396.17(c) bars use without a qualifying inspection and proof aboard. Consequences vary by state, so contact your inspector or enforcement authority before operating.
What does a DOT sticker mean?
It's visible evidence tied to a particular inspection or compliance program. Annual, state, and CVSA decals aren't interchangeable.
What does a truck inspection checklist typically include?
Brakes, tires, wheels, lights, steering, suspension, coupling, cargo securement, and emergency equipment. Add driver documents and the correct annual inspection evidence.
