CVSA Roadcheck 2026: Is Your Truck Ready for Inspection Week?
A 72-hour enforcement blitz across North America. Preparation before inspection week is cheaper than an out-of-service order during it.
The Commercial Vehicle Safety Alliance's International Roadcheck takes place May 12–14, 2026. During this 72-hour enforcement event, inspectors across North America conduct North American Standard Level I Inspections — a detailed 37-step process covering both the driver and the vehicle. For fleets and owner-operators running commercial trucks in the Charleston area, Roadcheck week is not something to ignore. A single lighting defect, brake adjustment issue, or documentation problem can result in a failed inspection, costly downtime, or an out-of-service order.
2026 CVSA Focus Areas
CVSA has announced two primary enforcement priorities for 2026: cargo securement and electronic logging device (ELD) tampering or falsification. Inspectors will be looking closely at how loads are secured, whether tie-downs are damaged or improperly rated, and whether spare equipment or tools are properly immobilized. On the ELD side, inspectors will check for falsified hours-of-service records, tampered devices, and patterns suggesting logs don't match actual driving activity.
What Inspectors Check During Roadcheck
Level I Inspections cover both the driver and the vehicle. On the driver side, inspectors review the commercial driver's license, medical certificate, record of duty status, seat belt use, and may check the drug and alcohol clearinghouse. On the vehicle side, the inspection covers:
- Brake systems — adjustment, condition, air lines, chambers, and hardware
- Tires — tread depth, condition, inflation, and sidewall integrity
- Lighting — headlights, brake lights, turn signals, marker lamps, and clearance lights
- Steering and suspension components
- Coupling devices and fifth wheel condition
- Cargo securement — tie-downs, binders, chains, dunnage, and load containment
- Exhaust system routing and emissions components
- Fluid and air leaks
- Windshield, wipers, mirrors, and horn
Common Issues That Get Trucks Put Out of Service
The most frequent out-of-service violations during Roadcheck involve brake adjustment, inoperative or missing lights, tire defects, and hours-of-service violations. Even a single inoperative marker light or a brake that is out of adjustment can result in an out-of-service order. For Charleston-area trucks, other common issues include:
- Air leaks in brake system lines or chambers
- Active ABS warning lights
- Fault codes for emissions or aftertreatment systems
- Loose wiring, damaged mud flaps, or missing reflectors
- Improperly secured spare tires or equipment on the body
Why Pre-Inspection Maintenance Matters
Catching a bad air line, a blown marker bulb, or an active fault code in the yard takes minutes. Finding the same problem at a scale house or DOT checkpoint takes the truck off the road. A quick walk-around and mobile diagnostic check before Roadcheck week is the most cost-effective preparation a fleet can do.
