DOT Inspection Levels Explained: Levels I–IX (2026)

Quick Answer

CVSA's North American Standard Inspection Program now lists nine levels. Level I is the full driver-and-vehicle inspection, Level II is a walk-around, Level III checks only the driver and paperwork, Level IV is a one-item special study, Level V is vehicle-only, Level VI covers radioactive loads, Level VII is state-mandated, Level VIII is electronic, and Level IX (new in 2026) is post-crash.

Key Takeaways

• Levels II and III are the most common in the U.S.: in 2023 they were 35.1% and 33.6% of about 3.01 million inspections, with Level I at 27.9%.
• Only Level I, V and VI inspections can earn a CVSA decal, and only if no critical vehicle violations are found. The decal is valid for the month issued plus two more.
• Level III never includes mechanical violations, but every level that includes the driver checks your license, medical certification, hours of service and record of duty status.
• Out-of-service (OOS) decisions follow CVSA's North American Standard Out-of-Service Criteria, updated every April 1. The 2026 edition added an OOS condition for ELD tampering.
• Every violation written on an inspection report goes into FMCSA's Safety Measurement System for 24 months, ticket or no ticket.

What are the DOT inspection levels?

"DOT inspection" is shorthand. The levels are defined by the Commercial Vehicle Safety Alliance (CVSA), and state, provincial and federal inspectors use them across the U.S., Canada and Mexico. The official definitions are on CVSA's All Inspection Levels page.

Two details matter in practice. If an inspector can't measure more than 20% of the exposed pushrods, a Level I has to be recorded as a Level II. And Level III reports can include traffic violations but not mechanical ones.

For the step-by-step version of the 37-step Level I, see our Level I inspection walkthrough.

Which inspection levels are most common?

Three levels make up nearly everything. FMCSA's 2024 Pocket Guide to Large Truck and Bus Statistics counted 3,011,902 U.S. inspections in 2023:

• Level II: 1,057,511 (35.1%), with 27.4% resulting in at least one OOS violation
• Level III: 1,011,089 (33.6%), with 6.3% resulting in an OOS violation
• Level I: 839,638 (27.9%), with 27.5% resulting in an OOS violation
• Level V: 96,326 (3.2%)
• Level IV: 5,867, and Level VI: 1,471

Enforcement blitzes skew toward Level I. During the May 12–14, 2026 International Roadcheck, inspectors ran 31,241 Level I inspections out of 54,575 total, according to CVSA's 2026 Roadcheck results.

CVSA doesn't set a time limit for any level. Industry estimates put a Level I at roughly 45–60 minutes and a Level III at 15–20 minutes. A defect or a log problem adds time.

What does the inspector check on the driver side?

Levels I, II and III all include the driver portion. Expect the inspector to look at:

• CDL or license: correct class, endorsements and restrictions, and valid status.
• Medical certification: since June 23, 2025, CDL and CLP holders no longer have to carry the paper medical card, because the electronic record controls under 49 CFR 391.41(a)(2). Non-CDL drivers of CMVs still must carry it. Keep a copy anyway in case your state record lags. See our DOT medical card guide.
• SPE certificate or medical variance: carry it if you have one.
• Record of duty status: today plus the prior 7 days (49 CFR 395.13). On an ELD, you'll display or transfer the logs; our guide on transferring ELD logs during an inspection covers each method.
• ELD information packet: a data-transfer instruction sheet, a malfunction instruction sheet, and blank paper logs for at least 8 days (49 CFR 395.22(h)).
• Hours-of-service compliance, seat belt use, and signs of alcohol or drugs.
• English proficiency (U.S. only): an OOS condition since June 25, 2025.
• Vehicle inspection reports and carrier identification and status.

At the 2026 Roadcheck, the top driver OOS reason was no medical card (27% of driver OOS violations), ahead of hours of service.

What changed in 2025 and 2026?

1. Level IX added. CVSA now lists a Level IX Post-Crash Inspection, used after a fatality, serious injury, high-profile crash, or when a jurisdiction requires it. CVSA is running 40-hour Level IX certification courses for law enforcement in 2026.
2. English proficiency became an OOS violation on June 25, 2025, under 49 CFR 391.11(b)(2) and FMCSA enforcement guidance.
3. The 2026 OOS criteria took effect April 1, 2026 with 17 changes. These included a new OOS condition when an ELD is tampered with so badly that the inspector can't tell when you drove or rested, and a clarification that an intrastate-only (K) CDL restriction puts you OOS only when you're outside your home state.
4. Level VIII is still in testing. CVSA defined it in 2017 and began an operational test in March 2024. CVSA says test results don't affect participating carriers' SMS scores.

What happens if you're placed out of service?

The OOS criteria are the pass/fail line. A vehicle OOS order under 49 CFR 396.9 means nobody can drive it, or tow it except with a crane or hoist, until the listed repairs are done. A driver OOS order for hours means you can't drive again until you can do so legally. For a property-carrying driver over the 11- or 14-hour limit, that usually means a 10-hour break.

If it happens to you:

1. Get the inspection report and read every violation before you leave.
2. Fix vehicle defects on site or call for a tow or mobile repair. Don't remove the OOS sticker yourself.
3. Hand the report to your carrier at the next terminal, or send it right away if you won't get there within 24 hours (49 CFR 396.9(d)(1)). Driver OOS forms go to your carrier within 24 hours (49 CFR 395.13(d)(3)).
4. The carrier certifies repairs and signs the report within 15 days, and keeps a copy for 12 months.
5. If a violation is wrong, file a DataQs challenge.

The CVSA Out-of-Service Criteria handbook is sold by CVSA. Brakes remain the top vehicle problem: in the 2026 Roadcheck, brake systems and the 20% defective-brakes rule together made up 39.1% of vehicle OOS violations.

How do inspection results affect your CSA scores and the CVSA decal?

Every violation on the report goes into FMCSA's Safety Measurement System, even if the officer gives you a warning instead of a ticket. Violations stay for 24 months. They're weighted by severity (1 to 10, with extra weight when the violation put you OOS) and by age: triple weight for the first six months, double for six to twelve months. Our CSA scores guide breaks down the math.

A clean Level I or V earns the CVSA decal. Its color shows the quarter it was issued: green for January–March, yellow for April–June, orange for July–September, white for October–December. A decal issued October 13, 2026 is good through December 31, 2026. While it's valid, inspectors generally won't re-inspect the vehicle unless they see a critical defect, run a Level IV, or pull random samples. The decal covers the truck, not you: a vehicle can earn a decal even when its driver is placed out of service.

How should you prepare for each level?

1. Level I and V: do a real pre-trip, including brake adjustment, air leaks, tires, lights and securement. Our pre-trip inspection checklist follows the same systems inspectors check.
2. Level II: assume anything visible from the ground will be checked. Lights, tires and leaking hubs are easy writes.
3. Level III: have your license, medical status, logs, ELD packet and shipping papers ready to hand over in under a minute.
4. Level VIII: keep your ELD, registration, UCR and operating authority current, since these are the data points it checks.
5. Every level: stay calm, answer questions directly, and don't argue at the scale. Dispute errors later through DataQs.

FAQ

What is the most common DOT inspection level?

In 2023 FMCSA data, Level II walk-arounds were most common at 35.1%, followed by Level III driver-only inspections at 33.6% and Level I at 27.9%.

Can a Level III inspection turn into a Level I?

Yes. The inspector decides the level, and if they spot a defect during a driver-only check, they can expand to a vehicle inspection. Mechanical violations can't be written on a Level III report itself.

How long is a CVSA decal good for?

It's valid for the month it's issued plus two months. A decal applied on July 28 expires September 30.

Do I still need to carry my medical card?

If you hold a CDL or CLP, no, since June 23, 2025, because the electronic record controls. Non-CDL drivers of commercial vehicles still must carry it, and carrying a copy anyway can save time if your state record isn't updated.

Who is allowed to do a DOT inspection?

CVSA-certified local, state, provincial, territorial and federal enforcement personnel. "Certified" means the government employee completed CVSA-approved training, and inspectors don't inspect vehicles on request.
