CVSA Inspections and the 2026 Out-of-Service Criteria Updates

A driver can spend months operating safely, only to have a roadside inspection reveal a defect that results in an out-of-service vehicle, costly delays, and an increased carrier profile risk score. While many drivers and carriers primarily associate inspections with enforcement actions such as tickets and penalties, roadside and scale inspections are an effective tool for improving highway safety. They help identify drivers and vehicles that may be only one failed component away from a serious incident, whether that defect is known or unknown to the operator.

What is a CVSA Inspection?

Across North America, roadside commercial vehicle inspections are conducted using standards developed by the Commercial Vehicle Safety Alliance (CVSA). Depending on the inspection level, an officer may examine the driver, the vehicle, or both.

The most comprehensive inspection, known as a Level I Inspection, includes a review of driver credentials and Hours-of-Service compliance, along with a detailed inspection of the vehicle's major safety systems such as brakes, tires, steering, suspension, lights, coupling devices, cargo securement, and required emergency equipment.

The goal is not simply to issue tickets. Rather, these inspections are intended to identify unsafe conditions before they contribute to a collision, breakdown, or other serious incident.

What are the Out-of-Service Criteria?

One of the most important tools used during a roadside inspection is the CVSA Out-of-Service (OOS) Criteria.

Think of the OOS Criteria as a list of defects or violations serious enough that a driver or vehicle must not continue operating until the issue has been corrected. While many defects may result in a warning or violation notice, an out-of-service condition is considered significant enough to immediately remove the vehicle or driver from service.

Examples can include severe brake defects, critical tire damage, major load securement issues, Hours-of-Service violations, or other conditions that present an elevated safety risk.

Each year, CVSA reviews and updates these criteria to improve clarity, address emerging issues, and promote consistent enforcement throughout North America.

What's New in the 2026 OOS Criteria?

With CVSA's annual update now in effect as of April 2026, this is a good opportunity for carriers and drivers to review how inspections are conducted and what inspectors are looking for.

Many of this year's revisions focus on clarifying existing language and improving consistency in enforcement. While some changes are administrative in nature, others provide more specific guidance for inspectors and carriers alike.

Three notable updates include:

1. Clarification for Damaged Wheel Rims

One update that stands out involves damage to wheel rims. New language has been added to address missing portions of a rim, specifically:

"Any missing piece exceeding 3 inches (76.2 mm) in length."

This addition provides a clearer threshold for determining when rim damage becomes severe enough to warrant an out-of-service condition, reducing the potential for inconsistent interpretation between jurisdictions.

2. Upper Coupler Countersunk Screws

The 2026 criteria also introduce language addressing broken or loose countersunk screws on a trailer's upper coupler assembly.

While this may seem like a minor component, the upper coupler plays a critical role in maintaining the integrity of the connection between tractor and trailer. Providing specific inspection guidance helps ensure these defects are identified and addressed consistently.

3. Passenger Carrier Emergency Exit Markings

For buses, motorcoaches, and other passenger-carrying vehicles, a new out-of-service condition has been added when emergency exits are not properly marked with operating instructions.

In an emergency, clearly identified exits can significantly impact passenger evacuation. This update reinforces the importance of ensuring emergency equipment and instructions remain visible and functional.

Another noteworthy change is the removal of the hub oil level defect from the Out-of-Service Criteria due to inconsistent application in the field. This reflects CVSA's ongoing efforts to improve clarity and consistency in enforcement.

Why These Changes Matter

CVSA's annual updates are not simply administrative revisions. They influence how roadside inspections are conducted, how violations are identified, and ultimately how carriers manage risk.

Understanding these changes helps carriers align their maintenance and inspection programs with current enforcement expectations. It also gives drivers a clearer understanding of what inspectors may be looking for during a roadside inspection.

Many of the items contained within the Out-of-Service Criteria are already components of a thorough pre-trip inspection under National Safety Code Standard 13. A strong inspection culture remains one of the most effective ways to prevent roadside violations before they occur.

How CayCan Safety Can Help

One of the services CayCan Safety provides is commercial vehicle inspections conducted using the same CVSA Out-of-Service Criteria used by roadside enforcement officers when conducting Levels I through V inspections.

Following the inspection procedures prescribed by CVSA, CayCan inspectors evaluate both driver and vehicle compliance, including:

• Brake systems
• Suspension and steering components
• Tires, wheels, and rims
• Lights and electrical systems
• Coupling devices
• Cargo securement
• Driver credentials and documentation
• Hours-of-Service compliance
• Required safety equipment
• Carrier-specific requirements

Unlike a roadside inspection, these assessments are conducted as an educational and preventative tool. They provide drivers and carriers with the opportunity to experience the inspection process, identify potential deficiencies, and improve compliance practices without the risk of roadside fines, enforcement action, or negative impacts to a carrier profile.

For many organizations, a CVSA-style inspection can serve as both a compliance assessment and a valuable training exercise, helping drivers better understand what to expect during an actual roadside inspection.

Final Thoughts

While it is rare for someone to be excited about being selected for a roadside inspection, being prepared for one should always be the goal. Staying current with the Out-of-Service Criteria and maintaining strong daily inspection practices can help carriers and drivers identify issues before they become violations, costly downtime, or out-of-service orders.

After all, it's much easier to correct a defect in the shop than explain it to an enforcement officer at the scale.
