Level I and Level II combined account for over 90% of all roadside inspections. Level II is typically the most common in routine enforcement because it's efficient for officers (walk-around only, no under-vehicle) while still catching most violations. Level I is the most comprehensive (37-step, under-vehicle) and is heavily used during CVSA International Roadcheck events. During 2025 Roadcheck, more than 50% of inspections were Level I and 23% were Level II. Being prepared for Level I means you're prepared for any inspection. Contact our sales team for inspection-level-specific compliance templates.

Several factors trigger inspections: weigh station automated screening (pulls CSA scores and OOS history in real-time, flags high-risk carriers to the inspection bay), visible defects observed by patrol officers (burnt lights, damaged tires, smoke, leaking fluids), random selection at checkpoints, complaints filed against a carrier, post-crash protocol, and CVSA enforcement campaigns like International Roadcheck (May), Brake Safety Week, and Operation Safe Driver. CVSA-certified officers operate under §396.9 authority to inspect any CMV in operation — no limit on frequency. A current CVSA decal (3 months valid from Level I/V/VI pass) generally exempts you from reinspection during the validity period.

An OOS (out-of-service) violation meets the North American Out-of-Service Criteria — meaning the defect is severe enough that the vehicle or driver cannot legally operate until corrected. The truck stops where it is (inspection site, shoulder, weigh station). A regular violation is cited but doesn't trigger an OOS order — the driver continues but must address the violation within timelines specified on the report. Under the 2026 CSA overhaul, OOS violations carry severity weight 2 vs 1 for non-OOS — meaning OOS findings hit your CSA score twice as hard. One OOS violation can take 20+ clean inspections to offset. Start your free trial to track inspection outcomes automatically.

No. CVSA-certified enforcement officers are authorized under 49 CFR §396.9 to enter upon and inspect any commercial motor vehicle in operation. Refusing an inspection results in an immediate out-of-service order plus additional penalties. The right approach: cooperate fully, present documents when asked, remain professional throughout the process. You have the right to receive a copy of the inspection report regardless of outcome, the right to professional and courteous treatment, and the right to challenge violations through the DataQs system if issued in error.

A CVSA decal is a sticker issued to vehicles that pass a Level I, Level V, or Level VI inspection with no critical violations. The decal is valid for 3 months. During that period, vehicles displaying a current decal are generally not subject to reinspection at weigh stations — which means significantly less time off the road and lower CSA inspection volume. Decals are placed on the windshield or visible location depending on inspection type (regular CVSA decal for Level I/V; nuclear decal for Level VI). Talk to our sales team for help maximizing CVSA decal eligibility.

February 2026's CSA SMS overhaul changed three things that affect every roadside inspection. First: OOS violations now carry severity weight 2 (vs 1 for non-OOS) — meaning each OOS finding hits your carrier score twice as hard as before. Second: the lookback period dropped from 24 months to 12 — concentrating the impact of recent violations. Third: Vehicle Maintenance was split into two separate BASIC categories (standard + Driver Observed), doubling the columns where DVIR and equipment violations can show up red. Net effect: one bad inspection now costs more than ever, and clean inspections matter more than ever. Sign up free to track CSA score impact in real time.
