CVSA's 2024 Out-of-Service Criteria Now in Effect

Starting today, the Commercial Vehicle Safety Alliance’s (CVSA) 2024 North American Standard Out-of-Service Criteria are now in effect. The 2024 out-of-service criteria replace and supersede all previous versions.


Certified commercial motor vehicle enforcement personnel utilize the out-of-service criteria to determine whether or not drivers or vehicles present an imminent hazard and should be placed out of service. The federal regulations, together with CVSA’s out-of-service criteria, provide the standards that drivers, motor carriers and law enforcement personnel use to ensure the commercial motor vehicles and professional drivers operating on North America’s roadways are safe and compliant.


Last year, the voting members of the Alliance approved 11 changes to the out-of-service criteria. In accordance with the CVSA Bylaws, the proposed changes were communicated to the voting members of the Alliance on Oct. 5, 2023, and ratified on Oct. 20, 2023. The out-of-service criteria are updated annually, effective April 1 of each year.


The following changes were made to the out-of-service criteria:

  1. A note was added to “Part I, Item 3. Commercial Driver’s License, c. Endorsements and Restrictions” to provide clarity on the status of a hazardous materials (HM) endorsement when the driver’s Transportation Security Administration screening/HM determination is expired, and the driver requires the HM endorsement.

  2. Ontario Class D license was removed from the note in “Part I, Item 4. Driver Medical/Physical Requirements, b. Medical Certificate.”

  3. “Part I, Item 7. Drugs and Other Substances, c. Prohibited from Performing Safety-Sensitive Functions” was amended to add the new 392.15 violation code and a note.

  4. The applicability table for commercial learner’s permit drivers was amended in “Part I, Item 7. Drugs and Other Substances, c. Prohibited from Performing Safety-Sensitive Functions.”

  5. Missing cam shaft bushings was added to the 20% criterion in “Part II, Item 1. Brake Systems, a. Defective Brakes, (5) Drum (Cam-Type and Wedge) Air Brakes, (a).”

  6. Watermarks were added to “Part II, Item 1. Brake Systems, a. Defective Brakes, 20% Criterion” and the end of 20% criterion to better identify the 20% out-of-service criterion and the 20% criterion relative to steering axle brakes.

  7. The word “shall” was changed to “may” in “Part II, Item 1. Brake Systems, q. Performance-Based Brake Test” to allow for inspector discretion in reference to the requirement of retesting the vehicle.

  8. “Part II, Item 3. Coupling Devices, c. Pintle Hooks, (1) and g. Hitch Systems (Excluding Fifth Wheels and Pintle Hooks), (1)” was amended to add latches that are not in use and ball hitches that are mismatched with the receiver.

  9. Language was added to the title of “Part II, Item 9. Lighting Devices (Headlamps, Tail Lamps, Stop Lamps, Turn Signals and Lamps/Flags On Projecting Loads), a. When Lights Are Required to Be On” to clarify that lights not being turned on does not constitute an out-of-service condition.

  10. A note was added to “Part II, Item 9. Lighting Devices (Headlamps, Tail Lamps, Stop Lamps, Turn Signals and Lamps/Flags on Projecting Loads).”

  11. By adding a new number (2) to “Part II, Item 12. Tires, b. Tires Other Than Those Found on the Front Steering Axle(s),” the rest of Item 12.b had to be renumbered.

These changes have been incorporated into North American Standard Inspection Program training materials, along with updated inspection bulletins, inspection procedures, operational policies and training videos.


There are different formats (e.g., print, electronic, other languages, etc.) of the 2024 out-of-service criteria available for purchase through the CVSA online store. It’s also available for purchase in CVSA’s app by searching “CVSA Out-of-Service Criteria” in the App Store or Google Play. Bulk orders of the handbook and the app are available.


CVSA hosted a webinar in January outlining the changes to the out-of-service criteria. The webinar is available to CVSA members through their CVSA member portal. Once logged in, click on the CVSA Learning tab, then click on “Roadside” to view the webinar.


For questions about the criteria, contact CVSA Director of Inspection Programs Kerri Wirachowsky via email or call 202-998-1650.

How Can Trucking Fleets Keep the Best Drivers?

Money and benefits may help you land an experienced truck driver, but it takes more than that to make sure he or she will stay. Communication and culture work together to create an atmosphere where a driver will be less likely to look for greener pastures elsewhere. But it takes work to craft a top-tier culture.

Where can one find fleets that have excelled in creating such a culture to use for benchmarking? The CarriersEdge Best Fleets to Drive For program. Mark Murrell, CarriersEdge co-founder, and leaders from two fleets that consistently are in the Top 20 Best Fleets to Drive For shared their insights with HDT. In this series, we’ll share their advice.

Company Culture: Make Sure Everyone is on the Same Page

To create driver stability, a company must first understand what it really needs and what a successful driver for that company will look like. They must know who they are and who will be a good fit.

Second, companies must slow down and take the time to find the person that fits. When they find that good fit, those drivers will not leave.

All of that must be driven from the top down, Murrell says. Read More

Will's Safety Tip

Spring is almost here! After a cold and blustery winter, it is very welcome, but allergic reactions from the budding plants, bugs, pollen and other allergens are definitely not. Allergic reactions can happen out of thin air, someone that has never had allergies might develop a reaction over years of exposure, so let’s discuss how to treat these reactions so you can do the right thing.

Call 911 if the person has ever had severe reactions in the past or has any of these symptoms:

If you have had severe allergies, you should keep two epinephrine injection kits with you at all times and readily available. Using the autoinjector as a precaution will not harm you. Call 911 even if you administer the injection.

Treating the Symptoms

Enjoy the warmer weather and Stay Safe!
