2012 OUT-OF-SERVICE CRITERIA
The Commercial Vehicle Safety Alliance (CVSA) has released the revised Out-of-Service Criteria (OOSC), effective April 1, 2012, for placing vehicles Out-of-Service at roadside safety inspections. CVSA is a nonprofit organization bringing federal, state and provincial government agencies together with representatives from private industry in the United States, Canada and Mexico who are dedicated to improving commercial vehicle safety.
The OOSC identifies serious violations that render a commercial vehicle or commercial vehicle operator an imminent danger to the general public. Commercial vehicles and operators placed Out-of-Service cannot operate until those items that rendered them out of service are remedied or repaired.
The OOSC contains minimum standards. CVSA emphasizes that operators should maintain their equipment at a higher level than presented in the OOSC.
The following information is only a summary and is limited to OOSC relevant to property-carrying operations. This summary does not necessarily cover the OOSC in full detail, so it is strongly recommended that operators also obtain the Official 2012 CVSA North American Standard Out-of-Service Criteria. The official version includes complete details, graphics and federal regulation references. For information on obtaining the official criteria, visit www.cvsa.org or call 202-775-1623.
The necessity for CVSA law enforcement members to implement and adhere to these standards is:
• A matter of law;
• Determined as necessary by the alliance to promote safety; and
• A professional obligation. Except where state, provincial or federal laws preclude enforcement of a specific item, CVSA law enforcement members shall comply with the North American Standard Out-of-Service Criteria.
A vehicle or combination vehicle is Out-of-Service if 20 percent or more of its service brakes have one of the following defects:
• Any steering-axle brake defect listed in next section.
• Won’t actuate effectively or friction material won’t contact drum/rotor.
• Audible air leak at chamber.
• Missing brake on any axle required to have brakes.
Drum air brakes
• Broken or missing brake shoe, lining, return spring (shoe or chamber), anchor pin, spider, cam roller, camshaft, pushrod, yoke, clevis pin, brake adjuster, parking brake power spring or air chamber mounting bolt.
• Loose air chamber, spider or camshaft support bracket.
• Lining has crack/void, observable on edge, wider than 1/16 inch.
• Portion of lining is missing, to the extent that rivet/bolt is exposed.
• Lining has crack, observable on edge, longer than 1-1/2 inch.
• Loose lining segment, permitting about 1⁄16-inch movement.
• Entire segment of lining is missing.
• Evidence of oil, grease or brake fluid contamination of the friction surface of the brake drum and the brake friction material.
• Lining thickness less than 1/4 inch or to wear indicator, if so marked, at shoe center.
