CVSA's North American Standard Inspection Program defines multiple inspection levels, from the comprehensive 40-minute Level I (driver credentials plus a full undercarriage vehicle check) down to specialized inspections for a single system or hazard class. Knowing what each level actually checks helps you keep the right paperwork on hand and know what to expect at a scale or checkpoint.
The most thorough inspection: driver's license, medical certificate, hours-of-service records, and seatbelt use, plus a full vehicle check that includes brake systems, coupling devices, exhaust, frame, fuel system, lighting, cargo securement, steering, suspension, tires, wheels/rims/hubs — including components the inspector has to get underneath the vehicle to check. Takes around 40 minutes.
Covers most of the same driver and vehicle items as Level I, but skips anything requiring the inspector to physically get under the vehicle. Common at weigh stations where inspectors need to move through vehicles faster — typically 15–20 minutes.
No mechanical inspection at all — this is a paperwork check: license, medical certificate, records of duty status/hours of service, seatbelt use, and carrier identification.
Level IV is a one-time special inspection used for targeted enforcement campaigns like CVSA's Brake Safety Week. Level V is a full vehicle-only inspection performed without the driver present, often at a terminal or after an impound. Level VI is an enhanced Level I inspection specifically required for shipments of radioactive material and highway route-controlled quantities.

Level II (walk-around) and Level III (paperwork-only) are the most common at weigh stations and roadside checkpoints, since they're faster for inspectors to run through than a full Level I.
CDL, medical certificate, your ELD or paper logs showing current hours of service, registration, proof of insurance, and your latest DVIR. Having these organized and easy to hand over is often the difference between a quick check and a drawn-out one.
Yes — a Level V inspection covers the entire vehicle without requiring the driver to be there, which is why it commonly happens at terminals, maintenance yards, or after a vehicle has been impounded.
