The North American Standard Level I and/or Level V are the only inspections that may result in issuance of a Commercial Vehicle Safety Alliance (CVSA) decal. To qualify for a CVSA decal, a vehicle must not have any violations of the items contained in the CVSA operational policy and North American Standard Out-of Service Criteria.
Inspections must be performed by and CVSA decals affixed by North American Standard Level I and/or Level V certified inspectors. The term "certified" as used in this section means the government employee performing inspections and/or affixing CVSA decals must have first successfully completed a training program approved by the Alliance. CVSA decals, when affixed, shall remain valid for a period not to exceed three consecutive months. Vehicles displaying a valid CVSA decal generally will not be subject to re-inspection.
However, nothing shall prevent re-inspection of a vehicle or combination of vehicles bearing valid CVSA decals, under the conditions specified in the section titled, "Re-inspection". For more detailed information on CVSA decals please visit the Alliance's website.
