Key Takeaways
- Level I = full NAS (driver + vehicle, including under-vehicle). Passing can put a CVSA decal on the windshield.
- Level II = walk-around. Level III = driver-only. A Level III can still OOS you on hours or a medical card.
- Levels IV–VI exist: special, vehicle-only (often at a yard), and enhanced radiological. Most fleets live in I–III.
- OOS criteria for brakes, tires, securement, and HOS are published by CVSA. You do not roll until they are fixed.
- Wrong unit or wrong code: DataQs, with evidence, not a month later.
- Bypass apps and skip-the-scale fines are other URLs. This page is the inspection itself.

CVSA Inspection Levels I–VI, Mapped
The Commercial Vehicle Safety Alliance standardizes six inspection levels so a Level I in Ontario means roughly the same work as a Level I in Texas. Officers still have discretion on which level to run. Traffic, weather, a blown steer they already see from the catwalk, or a blitz week can upgrade a driver-only stop into a full NAS. You do not get to pick the level. You get to be ready for Level I every time you roll, which makes II and III easy.

| Level | Name | What They Check | OOS Path |
|---|---|---|---|
| I | North American Standard | Full driver + vehicle, including under-vehicle items | Driver and/or vehicle; CVSA decal if you pass |
| II | Walk-Around Driver/Vehicle | Driver plus everything visible without going under | Driver and visible vehicle defects |
| III | Driver-Only | CDL, medical, ELD/HOS, driver credentials | Driver OOS (hours, license, medical) without a tire check |
| IV | Special | One-off or study items the officer is assigned | Whatever that special item fails |
| V | Vehicle-Only | Vehicle at a terminal or lot; driver often absent | Vehicle OOS on the carrier record |
| VI | Enhanced NAS (radiological) | Transuranic / HRCQ radioactive protocol | Not a dry-van random; specialized shipments |
Level I — North American Standard
Level I is the complete inspection. Driver: CDL class and endorsements, medical examiner certificate, record of duty status, ELD data transfer, shipping papers, and any hazmat documentation. Vehicle: service brakes, parking brake, steering, lights, tires, wheels, rims, frame, suspension, fuel system, exhaust, coupling (fifth wheel, pintle, safety devices), cargo securement, and other items on the NAS checklist. Officers use pits, creepers, or chocks. A 37-step memory from CDL school is the right mindset even if the published list has been revised.
Pass a Level I and you may receive a CVSA decal — the sticker that tells the next officer this combination was inspected to NAS within the decal period (commonly up to three months, subject to CVSA rules). The decal is not immunity. A new defect, a different trailer, or an International Roadcheck blitz can still put you on the pad. Fail a Level I and you may leave with an OOS sticker on a wheel or a driver OOS that parks you until hours recover.
The trailer you picked up two hours ago is still your Level I
Level II Walk-Around vs Level III Driver-Only
Level II covers the driver plus every vehicle item an officer can inspect without going under the combination. Lights, tires they can see, cargo from the side, coupling from a standing height, windshield, wipers. It is not a free skip of brakes. If a brake defect is obvious from a wheel-end or a pushrod they can see, it can still go on the report. Think of Level II as Level I without the pit.
Level III is credentials and hours. CDL, medical card, ELD, HOS, duty status, and related driver documents. A Level III can put you out of service for being out of hours, having no ELD when one is required, or a medical certificate that expired last month. It will not bless the bald steer you were going to replace Friday. Drivers who collect clean Level IIIs and skip pre-trips are farming a Level I on a bad day. ELD transfer failures during any level are scored as ELD problems — ELD violations and fines owns malfunction, form, transfer, and the 10-hour OOS, not this page.
Level I
Full NAS. Under the truck. Decal if you pass. Highest chance of vehicle OOS. Treat every pre-trip as this.
Level II
Walk-around. Driver plus visible vehicle. Faster than I. Still writes tires, lights, and securement they can see.
Level III
Driver only. Hours and license can still end your day. The truck is not certified legal just because nobody crawled it.
Levels IV, V, and VI — Special, Vehicle-Only, Radiological
Level IV is a special inspection. An officer may be collecting data on a component, following a complaint, or running a targeted check that is not a full NAS. The report still counts. Do not assume special means unofficial. Level V is vehicle-only, often at a carrier terminal, drop yard, or inspection pit without the driver. Fleet managers who think yard inspections are free because no CDL was present still put vehicle-maintenance points on the USDOT. The absent driver is not a loophole.
Level VI is the enhanced NAS for transuranic waste and certain highway-route-controlled quantity radioactive shipments. It is a specialized mechanical and radiological protocol, not something a dry-van owner-op collects on I-80. If you actually haul that product, your shipper and state already trained you. This page will not pretend Level VI is a sixth flavor of a random chicken-coop stop.
International Roadcheck is mostly Level I
OOS Criteria: Brakes, Tires, Securement, HOS
Out-of-service is a CVSA status: the vehicle or driver is too dangerous (or too illegal) to continue until the condition is corrected. Criteria are published in the North American Standard Out-of-Service Criteria. States adopt them so a 20% defective-brake call is not a local invention. You still need the current handbook energy, not a 2018 forum post. The rows below are the ones that park trucks, not a reprint of every lighting note.
| Area | Typical OOS Pattern | What You Do |
|---|---|---|
| Brakes | Defective-brake percentage (often cited as 20%), steer brake inoperative, audible air leak on a required brake | Repair before you roll; do not pump it to the next exit |
| Tires / wheels | Flat, exposed ply on steer, wrong tire for the axle, loose or missing lug | Replace or torque; photos help a later DataQ if the code was wrong |
| Cargo securement | Not enough tiedowns, broken winch, load that can shift, missing headerboard when required | Re-secure to 49 CFR 393; extra straps in the side box are cheaper than OOS |
| HOS / ELD | No ELD when required, cannot transfer, already out of hours, false log | Stop. ELD malfunction and transfer OOS belong on the ELD fines guide |
| Lights / coupling | No tail or stop when required, inoperative fifth-wheel lock, cracked approach plate listed as OOS | Fix at the site or tow; a missing mud flap is usually not this row |
| Driver fitness | Expired medical, CDL downgrade, disqualification | You do not drive. The truck can sit. CSA still sees it. |
Cargo securement OOS is a tiedown-count and device-condition problem under 49 CFR 393, not a vibe. Flatbed drivers who left a winch strap with UV rot in the rain are the case file. Van drivers who skipped load locks on a mixed pallet wall still get written. See FMCSA cargo securement for device choice. HOS OOS is hours already gone or no records. Do not argue 14-hour math from memory while the ELD is on the officer’s tablet. HOS violations covers the clock. This page covers that HOS is a Level I and Level III OOS path.
Brake OOS is the expensive one. A steering-axle brake that does not apply, a combination over the defective percentage, or an air leak that kills a required brake will park you on the shoulder with a tow bill. Pre-trip that includes a brake check is cheaper than a mobile tech at a scale. Tire OOS on a steer (exposed ply, flat, wrong application) is how people buy a new tire in a parking lot at 2 a.m. Carry a plan for steer replacement, not a hope.
DataQs — Challenging the Inspection Record
Inspections feed MCMIS and then CSA. If the report is wrong — wrong VIN, a violation coded against the tractor that belonged to the trailer, an HOS citation that the ELD export contradicts — you request a review through DataQs. Attach the inspection report, photos, repair invoices, ELD files, and a short factual narrative. State reviewers, not a Facebook moderator, decide. Process and timing: DataQs challenge process.
DataQs is not a charm against a real OOS. If the brake was actually inoperative, a challenge wastes months. If the officer wrote 396.3(a)(1) for a defect that has a more specific code, or cited the wrong unit, that is a DataQ. File while the photos are still on your phone. CSA severity and recency weights mean a clean challenge still helps more now than in month 23. After the data is right, how to improve CSA score is the operational fix, not a second DataQ.
Good DataQ evidence
Timestamped photos of the cited part, the inspection report number, ELD transfer logs, a shop invoice dated the same day, and a VIN photo. Calm tone. Ask for the specific correction.
Bad DataQ evidence
He was rude, everyone runs this, or a dashcam of the officer walking up. Attitude is not a violation code. Neither is a CB rumor that the scale was targeting out-of-state plates.
How to Walk Into a 2026 Inspection
| Step | Do This | Skip This |
|---|---|---|
| 1. Pre-trip like Level I is coming | Brakes, tires, lights, securement, coupling — actually look | A two-minute walk because you ran this trailer yesterday |
| 2. Paper in one place | CDL, med card, cab card, registration, IFTA, shipping papers | Three visors and a glove box of 2023 receipts |
| 3. ELD ready | Device on the list, data-transfer method you have practiced | Hoping the officer will take a screenshot of a dead tablet |
| 4. Know the level | Ask what level it is; it changes what they will crawl | Arguing that Level III means the truck is legal |
| 5. If OOS, fix then roll | Repair invoice, photos, officer release | Rolling on a verbal they will never remember |
| 6. If the report is wrong | DataQs with evidence, promptly | A Facebook rant six months later |
Apps that tell you whether a scale is open are not an inspection strategy. They are location tools. Weigh station apps covers PrePass, Drivewyze, and what a green light actually authorizes. If you are already on the pad, the app cannot change the level. Hands on the wheel until asked, documents ready, no coaching the officer on CVSA policy. If they put you OOS, the next call is a shop, then dispatch — /dispatch/ if we are running your freight — not a debate about Level numbers.
- Decal: a current CVSA decal after a clean Level I is useful. It is not a hall pass for a new trailer or a blown tire.
- PSP: inspections also live on your PSP. Carriers hiring you will see the last three years. How to run a PSP.
- Walk: rolling against an OOS, coaching another driver to hide a log, or treating Level III as a mechanical inspection.
Why This Is Not the Skip-Fine or Bypass URL
Searchers mix three intents: what a Level I checks, how to legally bypass an open scale, and what the ticket costs if you blow past a chicken coop. This slug is the first. Weigh station apps is PrePass, Drivewyze, and Trucker Path as tools. Fail-to-stop fines stay on skip-weigh-station-fines. We will not reprint dollar ranges, camera enforcement, or red-light rules here. GSC can have all three without cloning.
Where to go after this page
ELD on the pad: ELD violations and fines. Bypass hardware: weigh station apps. Challenge the report: DataQs. If the truck is legal and you need freight: dispatch.
A clean inspection culture is a maintenance culture. Pre-trip tire walk: pre-trip tire inspection. Broader roadside manners: police interaction tips. Weigh-station procedure without the fine table: how weigh stations work. None of those pages replace knowing which level you are in while an officer is writing.
How Inspection Levels Feed CSA BASICs
Every inspection, including a clean Level III, is an event in MCMIS. Violations score into BASICs: vehicle maintenance from brakes and lights, HOS from logs and ELDs, driver fitness from medical and license, unsafe driving from moving violations written at the stop, hazmat from placard and papers. Severity weights and recency weights mean an OOS brake from a Level I hurts more than a lighting note from a Level II. The level is not a BASIC. The violation codes are.
A clean Level I with a decal still counts as an inspection with no violations — that is good exposure, not a punishment. Carriers who hide from scales to keep a blank snapshot are farming a worse day. Measure yourself on how to check CSA score and the seven BASICs. This page will not reprint percentile tables. It will tell you that Level I is where vehicle-maintenance points are born.
International Roadcheck and Operation Safe Driver weeks raise the odds of Level I. You do not need a different personality. You need the same pre-trip you should have had in February. If you are OOS on hours, the inspection level is almost a footnote — you were already illegal. If you are OOS on a steer tire you skipped at 4 a.m., the Level I just made it official. Fix the tire culture, then worry about which CVSA number was on the report.
Clean inspection, still an event
A no-violation Level I or III is a good data point. It does not erase last month's OOS. It does help the denominator. Do not skip the snapshot review because the decal looks pretty.
OOS is heavier than a note
CVSA OOS violations carry more severity. Repair, document, DataQ only if the code or unit is wrong. Then change the shop schedule so the next Level I is boring.
CVSA Decals, Blitz Weeks, and What the Report Number Means
A passing Level I can put a CVSA decal on the windshield. The sticker tells the next officer this combination was inspected to North American Standard within the current decal window — commonly up to three months, subject to alliance rules and whether the trailer changed. It is not immunity. A new defect, a different trailer, a blown steer, or an International Roadcheck week can still put you on the pad. Do not argue “I have a decal” while a tire is flat. The inspection report number is what MCMIS and your PSP will show. Photograph the report before you leave the scale. If a violation is wrong, that number is what you take to DataQs.
Brake-emphasis weeks and cargo-securement blitzes are public CVSA communications. Prepare like every week is a blitz: pushrods, tires, lights, and tiedown count. ELD transfer still happens at every level that looks at the driver — practice it parked, not while an officer is waiting. That procedure lives on ELD violations and fines, not on a skip-the-scale page.
Ask what level it is, then shut up and produce paper
Frequently Asked Questions
What is a CVSA Level I inspection?
Level I is the North American Standard Inspection: a full examination of both the driver and the vehicle. The officer checks credentials, medical card, ELD or RODS, HOS, and then inspects the truck and trailer including items that require getting under or around the combination — brakes, coupling, frame, suspension, lights, tires, wheels, cargo securement, and more. It is the inspection that can put a CVSA decal on the glass when you pass. It is also the inspection that most often produces vehicle OOS orders. Level I is not a courtesy walk. Budget the time.
What is the difference between Level II and Level III?
Level II is a walk-around driver/vehicle inspection. The officer still looks at you and at everything that can be seen without crawling under the vehicle. Brakes that need a pit or creeper are not a Level II specialty. Level III is driver-only: license, CDL, medical examiner certificate, ELD, HOS, and related driver paperwork. A Level III can still put you out of service for HOS or a missing medical card without anyone looking at a tire. Drivers who say I only got a Level 3 so I am fine are describing a different risk, not a free pass.
What are CVSA Levels IV, V, and VI?
Level IV is a special inspection — one-off or targeted items, often for a study, a complaint, or a specific component. Level V is a vehicle-only inspection, typically at a carrier yard or drop lot without the driver present; it can still generate vehicle violations on the carrier CSA. Level VI is the enhanced NAS inspection for transuranic waste and certain highway-route-controlled radioactive shipments: a more exhaustive mechanical and radiological protocol, not a random dry-van event. Most owner-operators will never see Level VI. You will see I, II, and III constantly.
What out-of-service criteria apply to brakes, tires, securement, and HOS?
CVSA publishes North American Standard Out-of-Service Criteria, updated on a published cycle. Brakes: a defective-brake percentage (commonly described as 20% of the combination) or specific failures such as a steering-axle brake not operating. Tires: flat, exposed ply on a steer, or other listed damage. Cargo securement: not enough tiedowns, failed devices, or load that can shift. HOS: no ELD when required, hours already over, or no records. OOS means you do not roll until the defect is fixed or the hours recover. It is not a suggestion. ELD-specific OOS and fines live on our ELD violations guide, not here.
Does a CVSA inspection at a weigh station mean I skipped a scale?
No. This page is what happens after you are already in the system: inspection level, OOS criteria, and DataQs. Legal bypass programs, red-light versus green-light, and fail-to-stop penalties are different URLs — weigh station apps for PrePass and Drivewyze, and the skip-fine guide for those penalties. A Level I inside the chicken coop is an inspection, not a bypass tutorial. We will not clone those pages into this slug.
How do I challenge a bad inspection with DataQs?
DataQs is FMCSA’s system for requesting a review of crash and inspection data. If the officer cited the wrong unit, the wrong violation code, or a defect you can prove was not present, you file through DataQs with documents — repair invoices, ELD exports, photos, the inspection report. States have their own review timelines. Winning a DataQ removes or amends the record that feeds CSA. Losing it leaves the violation. Process detail lives on our DataQs challenge guide. Do not wait six months; CSA clocks start when the inspection posts.
Will a Level I failure ruin my CSA score?
It can. Vehicle maintenance, unsafe driving, HOS compliance, driver fitness, and hazmat BASICs all take points from inspections, weighted by severity and recency. An OOS violation is heavier than a note. One ugly Level I is not automatic Unsatisfactory, but a pattern of brake and tire OOS is how insurance and brokers start asking questions. Read CSA BASIC categories and how to improve CSA score after you pull the snapshot. The inspection level is the event. CSA is the hangover.
What should I have in my hand before the officer starts a Level I?
CDL, medical examiner certificate (or the electronic equivalent your state uses), ELD ready to transfer data, shipping papers, and a calm pre-trip you actually did. If the ELD cannot transfer, that is its own violation path — see ELD violations and fines. Cab clutter that hides a fire extinguisher or triangles is a gift. You cannot talk a flat steer tire into a Level III. You can make a Level I shorter by having paperwork in one folder, not three visors.
Why This Is Its Own URL
Search intent is inspection level and OOS, not a skip ticket
Level I vs II vs III is a checklist query. Skip-fine is a penalty query. Weigh-station apps are a hardware query. This page is NAS levels, OOS criteria, and DataQs.
We dispatch carriers; we do not staff a scale
ELD OOS: ELD violations and fines. Apps at the coop: weigh station apps. Freight when you are rolling: /dispatch/.
Clean Inspections Travel With the Truck — So Does Freight
O Trucking dispatches motor carriers that keep equipment inspection-ready. We do not clear OOS stickers, file DataQs for you, or sell PrePass. If a Level I just parked you, fix the defect first, then talk dispatch.
