Out-of-Service Criteria changes land April 1st
The Commercial Vehicle Safety Alliance’s Out-of-Service (OOS) Criteria will soon undergo a wide-ranging update affecting roadside inspections for both drivers and their commercial motor vehicles.
From license restrictions and English‑language proficiency (ELP) to log falsification, brake systems, cargo securement, and wheel defects, the revisions clarify long‑standing enforcement questions, add new OOS conditions in emerging problem areas, and refine existing criteria to better align with federal regulations and real‑world inspection practices.
The following is a summary of key changes that go into effect April 1, 2026. Review the changes to ensure your drivers and vehicles will still pass a roadside test.
Driver OOS Criteria
- ELD tampering: With electronic logging device (ELD) tampering becoming a growing concern, the criteria for placing drivers OOS for log falsification have been clarified to address situations where a record is falsified so much that the officer cannot determine when the driver was driving and/or resting. Drivers will continue to be placed OOS “until such time as eligibility to drive is re-established” if a required log is false due to inaccurate entries and the officer is able to determine when driving and rest breaks occurred. A new criterion was added to place drivers OOS for 10 hours (or 8 hours for passenger carriers) for ELD tampering that makes the entire record suspect and the inspector is unable to verify when driving and resting occurred. Officers will cite 49 CFR 395.8(e)(2) for ELD tampering where the truth cannot be ascertained, and paragraph (e)(1) for false logs when the officer can determine rest periods and drive time.
- ELP violations: A new violation was added to place drivers OOS if the driver cannot satisfy the ELP requirements of 391.11(b)(2), per enforcement guidance issued by the Federal Motor Carrier Safety Administration (FMCSA) in May 2025.
- License-restriction violations: Officers will begin using new citation codes for license-restriction violations, to distinguish them from endorsement-related violations. Drivers without a commercial driver’s license (CDL) will be cited for “392.2NCDLR” (instead of 391.11(b)(5)) if violating a restriction, while CDL holders will be cited for “392.2LCDLR” (instead of 383.23).
- In-state-restricted drivers: The CVSA has clarified the standard for enforcing the “K” (in-state only) restriction, which is intended to keep the driver in their home state. Such drivers will only be placed OOS if they are actually operating in another state at the time of the inspection.
- Alcohol content threshold: The OOS Criteria will now specify the alcohol concentration at which drivers will be placed OOS when in possession of wine or beer, making it easier for officers to apply the existing standard. Drivers will be placed OOS if they possess wine or beer that contains 0.5% or more alcohol by volume or distilled spirits in any dilution.
Vehicle OOS Criteria
- Air connections: The criteria for air-brake hose/tubing were revised to change the term “gladhands” to the more inclusive “service air connections.” In addition, the criteria were changed to clarify the conditions for placing vehicles OOS when the air system is disconnected but still functional.
- Brake pad thickness: The standard for front-axle hydraulic brake pad thickness was updated to say “less than 1/16 inch” instead of “1/16 inch or less” to reflect a thinner measurement than found in 49 CFR 393.47(d)(1).
- Parking brakes: “Parking Brake” was changed to “Parking/Emergency Brake” in the section on parking brake systems due to confusion about whether an automatic transmission placed into Park was considered to have a parking brake control.
- Log securement: New criteria were added to address the use of the “ExTe Com90” hydraulic load securement system for logs.
- Wire rope: A new wire-rope damage chart was added to help inspectors determine when a wire rope is damaged to the point that it’s OOS.
- Upper couplers: A new OOS criterion was added for broken or loose countersunk screws in an upper coupler. Previously, the criteria only addressed bolts, not countersunk screws.
- Rims: A new OOS criterion was added for a broken wheel/rim that has “any missing piece exceeding 3 inches (76.2 mm) in length.”
- Wheel hub lubricant: The criterion for placing vehicles OOS when there is “no visible or measurable amount of lubricant showing in hub” was removed. The CVSA concluded that there is no good way for inspectors to know if there is oil in a hub that requires oil, or grease in hubs requiring grease, due to the many varieties of hubs and hub caps/covers in the marketplace.
- Emergency exit markings: A new criterion was added for emergency exits that are “not properly marked with operating instructions.” The instructions are needed whether the exit is a required exit or a marked exit.
- Placarding: The prior criteria placed vehicles OOS if “50% or more of the required placards for a hazard class are missing.” This was clarified to read “50% or more of the required placards for a category of material (hazard class or division) are missing.”
Key to remember: A variety of changes to the North American Standard Out-of-Service Criteria take effect on April 1, 2026. Reviewing the changes can help avoid being placed out of service.
