    2026 Updates

    Key changes for the April 1, 2026 edition of CVSA’s North American Standard Out of Service Criteria Handbook:

    1. Brake Hose Chafing Thresholds Further Clarified: New measurement guidance specifies that any brake hose chafing exposing reinforcement material over a length greater than 1 inch is now an out-of-service condition, aligning inspection consistency across jurisdictions.
    2. Steering System Free Play Limits Revised: Updated steering free-play tables now include additional axle configurations and reduced allowable movement for certain power-steering systems. Exceeding the revised limits will result in an out-of-service determination.
    3. Cargo Securement: Synthetic Webbing Straps Standardized: Synthetic webbing straps showing fraying, cuts, or abrasion exceeding 10% of strap width are now automatically considered out-of-service, replacing the previous subjective “significant damage” language.
    4. Fuel System Leaks Expanded to Include EV Battery Coolant Leaks: For electric commercial vehicles, any active coolant leak from the battery thermal-management system is now an out-of-service condition due to fire-risk potential.
    5. Suspension Air Spring Mounting Requirements Updated: A missing or detached air-spring upper or lower mounting bolt now constitutes an immediate out-of-service violation, even if the air spring remains inflated.
