Every year, the Commercial Vehicle Safety Alliance reviews and updates the North American Standard Out-of-Service Criteria. These updates took effect on April 1, 2025.
The criteria define when a commercial vehicle or driver must be removed from service due to safety violations. They establish the threshold for what constitutes an imminent hazard during inspection.
For attorneys, insurers, and expert witnesses, these standards often surface in litigation involving accidents or compliance failures. They serve as a technical reference showing when enforcement should have occurred.
The standards function as a pass/fail safety check applied during roadside inspections. They identify conditions serious enough to warrant immediate removal from service.
When inspectors find violations meeting these criteria, the driver or vehicle cannot return to operation until the defect is corrected and verified.
The criteria provide a clear baseline for enforcement consistency. They work alongside Federal Motor Carrier Safety Administration (FMCSA) regulations to ensure uniform application across jurisdictions.
An expert witness often references these standards when assessing whether a vehicle met regulatory expectations. In many disputes, these findings form part of the factual record used to establish compliance.
The 2025 edition incorporated 15 approved amendments. The changes primarily address driver qualification requirements and several mechanical systems, including brakes, tires, suspensions, and lighting.
Each revision aims to clarify enforcement procedures and remove ambiguous language that previously caused inconsistent application.
All commercial vehicle drivers must now maintain a valid medical certificate. Operating without one results in an immediate out-of-service order.
A commercial learner’s permit holder must be accompanied by a fully authorized commercial driver’s license (CDL) holder who is not under any driving prohibition. If the supervising driver’s status is restricted, both drivers are considered out of compliance.
The update also clarifies how Canada’s Transportation of Dangerous Goods certificates are recognized. This harmonizes U.S. and Canadian definitions for smoother international crossings.
Inspectors now treat inoperative brakes caused by unplugged electrical connectors or disconnected service lines as single violations. Previously, each brake might have been counted separately.
Language referencing crimped hoses has been removed. The Alliance determined that crimping affects brake release more than application, making it inappropriate as a standalone condition.
Any tire showing a sidewall leak is now classified as out-of-service, regardless of whether the vehicle has an Automatic Tire Inflation System. The separation between radial and bias tires was removed.
A cracked or broken U-bolt bottom plate is now clearly defined as an out-of-service defect. New diagrams distinguish between bolts and bushings within spring hanger assemblies.
A new section specifies conditions for projecting load lamps. Updated diagrams provide visual reference for inspectors, indorsing uniform application during daytime and nighttime operations.
These updates were introduced to reduce ambiguity, modernize inspection criteria, and improve cross-border enforcement. As commercial vehicle systems evolve, outdated definitions can lead to inconsistent interpretations.
This becomes important when inspection results are later reviewed in technical investigations. The new criteria provide a clear reference for what constituted a disqualifying defect at the time of inspection.
For example, a tire leak that might not have previously been recorded as out-of-service now has a defined regulatory basis. This distinction may clarify whether enforcement aligned with established procedure.
Carriers must verify that all drivers maintain valid medical certificates and that supervision arrangements for learners meet the updated standards. This requires regular review of qualification files and training assignments.
Updated brake and tire conditions mean fleet maintenance programs must incorporate these definitions into pre-trip inspections. Documenting these checks provides traceable compliance evidence during audits.
Out-of-service determinations can appear in litigation involving vehicle collisions or a mechanical failure. When a vehicle has a documented violation, attorneys often reference the specific section to understand whether it represented an imminent hazard.
Expert witnesses review inspection logs and maintenance reports to determine whether findings are consistent with the definitions in effect at that time.
Properly maintained inspection and repair records may demonstrate that a condition developed after a compliant inspection. The criteria provide the standardized baseline used by enforcement and technical experts alike.
The key is to align internal procedures with the current standards. Carriers should conduct periodic audits of driver medical certifications and ensure records reflect current status.
Maintenance personnel must be trained to recognize the updated brake, tire, and suspension definitions. Even minor wording changes require procedural updates to inspection checklists.
The Alliance application provides access to the most recent standards, diagrams, and references. It is available in multiple languages and formats, back up consistent interpretation during fleet training.
Accurate record-keeping is the foundation of defensible compliance. Inspection reports should document not only findings but also corrective actions and verification of repair.
Expert witnesses use the criteria as an objective framework when conducting vehicle inspections or reviewing enforcement reports. Their role is to compare documented conditions against the published standards.
When evaluating a braking defect or tire failure, the expert identifies whether the issue met the defined out-of-service threshold. This ensures findings are based on objective criteria rather than opinion.
A post-incident inspection showing a disconnected brake line now has an explicit classification rather than relying on interpretation. This gives clear, fact-based testimony about the technical condition of a vehicle.
The standardized language helps remove uncertainty when experts describe inspection findings in deposition or court. Because the updates are ratified annually and published by the Alliance, they represent the most current interpretation.
When an expert refers to the 2025 criteria during a review, attorneys and insurers can verify the cited section and confirm that the finding matches the published standards.
This consistency benefits all parties involved in vehicle-related litigation, allowing technical evidence to stand on recognized, objective foundations.

The criteria define when a commercial truck, trailer, or driver presents an imminent hazard that requires removal from service until corrected. Inspectors apply these standards during roadside checks.
When a vehicle or driver is placed out of service, operations must cease until the condition is corrected and verified. Continuing to operate while under an order may result in additional penalties.
The criteria themselves do not impose fines. They provide the technical basis for determining when enforcement action applies.
