CVSA Decal Explained | How Trucks Earn and Keep One

A CVSA decal is a coloured sticker affixed to a commercial motor vehicle by a CVSA-certified Level I, V, or VI inspector after the vehicle passes an eligible inspection with no critical vehicle inspection item violations per the North American Standard Out-of-Service Criteria. The decal displays the last digit of the calendar year (2026 = "6") at the top and the CVSA trademarked logo. Standard decals are single-colour and apply to the power unit; Level VI decals are blue, hole-punched with year/month/day, and apply to the entire vehicle and/or combination. Vehicles displaying a valid CVSA decal are generally not subject to re-inspection during the coverage window, which is the month of issuance plus two additional calendar months. The decal is a probability-shifter that reduces duplicate roadside inspections rather than a legal shield — inspector discretion allows re-inspection if an obvious defect is observed. Critically, the CVSA decal applies to the vehicle condition only, not the driver — a driver can be placed out-of-service on a Level III (driver-only) inspection while the vehicle continues to display a valid decal.

Three pathways lead to a CVSA decal. Level I North American Standard Inspection: the most comprehensive standard inspection, covering both driver credentials (licence, medical card, hours of service, seat belt) and full vehicle exam (brakes including trailer connections, coupling devices, exhaust, frame, fuel system, lighting, safe loading, steering, suspension, tires, wheels/rims, windshield wipers, emergency equipment). If no critical vehicle inspection item violations are detected, the inspector affixes a standard CVSA decal. Level V Vehicle-Only Inspection: same vehicle-side scope as Level I but without the driver present, typically conducted at a motor carrier's premises. Standard decal issued on clean vehicle findings. Level VI North American Standard Inspection for Transuranic Waste and Highway Route Controlled Quantities of Radioactive Material: special-purpose inspection required at point of origin for radioactive shipments. Requires the vehicle and/or combination to be defect-free (a stricter threshold than "no critical items"). Results in the blue Level VI decal, valid for single trip only. Level III (driver-only) and Level IV (special study) inspections do not result in CVSA decals. Inspectors must be CVSA-certified for the specific level they are conducting to affix a valid decal.

Standard CVSA decals are valid for the month of issuance plus two additional calendar months — a maximum coverage window of approximately three calendar months. The rule is month-based, not date-based, so a decal issued late in a month grants a shorter effective bypass window. Example: a decal issued on July 28, 2026 expires September 30, 2026 (not October 28, 2026). A decal issued on July 3 covers essentially the same expiry date but a longer usable period. The quarter-corner-cut system on the decal itself makes the exact issue month readable at a glance: both upper corners removed = 1st month of the calendar quarter; upper right corner only removed = 2nd month; no corners removed (intact) = 3rd month. Combined with the year digit at the top of the decal, an officer can determine the exact month and year of issuance in under 2 seconds. No penalty applies for operating a vehicle with an expired CVSA decal — the vehicle can still operate legally, it just loses the inspection-bypass advantage. Level VI decals operate on different rules: single-trip validity only, hole-punched with exact year/month/day, not valid after the specific shipment for which they were issued.

No — and this is one of the most important operational distinctions in the CVSA decal program. CVSA decal criteria apply only to the condition of the vehicle, not the driver. An inspector may issue a CVSA decal for a vehicle that passes Level I or V inspection cleanly even if the driver receives an out-of-service violation on the driver-side portion of that same Level I inspection. This means: a driver who fails their HOS check, presents an invalid medical card, or is otherwise placed OOS can trigger driver-side citations while the vehicle they were driving still earns and displays a valid CVSA decal. Conversely, drivers operating a vehicle with a valid CVSA decal remain subject to Level III driver-only inspections at any point during the decal's coverage window — the decal does not protect against driver-side re-inspection. Practical consequence for fleets: earning decals fleet-wide reduces vehicle re-inspection frequency but does not reduce driver-inspection frequency. Structural compliance programs need to run driver-credential management and vehicle-inspection preparation as parallel workstreams, not as one combined effort.

Standard CVSA decal placement: lower right corner of the exterior surface of the passenger-side windshield on the power unit. This placement complies with 49 CFR 393.60(e)(1) and (2), which restricts windshield decals to areas that do not interfere with the driver's view and are outside the sweep of the wiper. The placement is standardised across North America so inspectors can locate and read the decal quickly at scale-house pull-ins, roadside stops, or during roving patrol observation. Level VI decal placement differs: passenger side edge of the windshield near the top, with the bottom edge of the decal no more than 6 inches from the top of the windshield. It must be out of the sweep of the wiper and not affixed where it would interfere with the driver's view. When a Level VI decal is affixed, a standard CVSA decal is also applied per operational policy if the vehicle does not already have a valid standard decal. Any expired regular decal or any previous Level VI decal must be removed before a new decal is affixed. Verify current CVSA operational policy and 49 CFR 393.60 windshield decal placement restrictions before affixing or removing decals — CVSA policy is updated periodically and this article reflects the position at time of writing.
