Every May, the Commercial Vehicle Safety Alliance (CVSA) runs the International Roadcheck, a 72-hour enforcement blitz across the US, Canada, and Mexico. Last year, CVSA inspectors completed over 56,000 inspections in three days and placed nearly 1 in 5 trucks out of service. The violations driving those numbers weren’t surprises: brake systems, tires, and hours-of-service gaps accounted for the vast majority. In 2026, CVSA has named driver fitness and HOS compliance as the official focus area, putting ELD data and rest period accuracy squarely in the crosshairs.
What shippers often don’t see coming is how directly the DOT Blitz can touch their supply chain. When a truck is placed out of service during a Roadcheck inspection, that load waits — sometimes hours, sometimes longer — with no automatic reroute and no advance warning. By the time the delay shows up in your visibility tool, the decision has already been made upstream. Understanding what drives those outcomes is the first step to planning around them.
Roadcheck 2026 Prep: What Proactive Shippers Do Before May 12
Here’s where your preparation starts.
Start the carrier conversation now — not May 11. Ask direct questions: What’s your out-of-service rate? How do you handle a mid-route inspection failure? Who owns compliance internally? If the answers aren’t clear, that’s something to pay attention to.
Build time buffers into May 12–14 delivery windows. A 2–4 hour buffer on delivery appointments is often the difference between a service exception and a non-event. Communicate adjusted windows to your receiving team before the DOT Blitz starts, not after a delay is already in motion.
Verify your freight documentation before it leaves the dock. CVSA inspectors cited shipping paper violations in more than 20% of hazmat out-of-service cases in 2025. Inaccurate BOLs and incomplete manifests don’t just slow down the inspection — they extend how long your freight sits. Get documentation right before the truck rolls.
Flag your critical loads and have a contingency conversation. Identify time-sensitive or high-value shipments scheduled for the International Roadcheck window and talk to your carrier now about routing options. One option is moving a critical load one day earlier is one of the lowest-cost risk management decisions available to you.
Add extra buffer on cross-border moves. Roadcheck 2026 enforcement spans all three countries simultaneously. US–Canada and US–Mexico freight can face inspection pressure on both sides of the border. Cross-border schedules need more cushion than domestic lanes during this window.
Know what to ask when evaluating carrier compliance. CSA scores, out-of-service rates, and safety program depth aren’t just compliance metrics — they’re indicators of how your freight will perform during enforcement windows like Roadcheck. This season is a useful forcing function for those conversations.
What Separates a Strong Carrier Partner During DOT Blitz Season
The carriers that perform well during International Roadcheck aren’t doing anything different in the week before May 12. Their drivers run within HOS limits as a standard practice. Their vehicles are maintained to CVSA inspection standards year-round. Their compliance team isn’t scrambling — because there’s nothing to scramble about.
That gap — between carriers that are always inspection-ready and carriers that treat Roadcheck as a deadline — is exactly where shipper supply chains absorb risk. The 72-hour blitz just makes the gap visible.
International Roadcheck 2026: Frequently Asked Questions
The following questions are among the most common we hear from shippers in the lead-up to Roadcheck season.
What is International Roadcheck?
International Roadcheck is an annual 72-hour commercial vehicle enforcement event coordinated by the Commercial Vehicle Safety Alliance (CVSA). It takes place simultaneously across the United States, Canada, and Mexico. During the event, law enforcement officers conduct Level I inspections — the most comprehensive inspection category — at a significantly higher rate than any other time of year.
When is International Roadcheck 2026?
The 2026 International Roadcheck runs May 12–14, 2026. The enforcement window opens at 12:01 AM on May 12 and closes at 11:59 PM on May 14, local time.
What is the 2026 Roadcheck focus area?
CVSA has designated driver fitness and hours-of-service (HOS) compliance as the 2026 International Roadcheck focus area. Inspectors will pay particular attention to ELD data accuracy, rest period compliance, medical certification currency, and CDL validity. Vehicle inspections remain comprehensive regardless of the annual focus.
What is a Level I DOT inspection?
A Level I inspection is the most thorough category of commercial vehicle inspection under CVSA’s North American Standard. It covers 37 checkpoints across both the driver and the vehicle, including brake systems, tires, lights, steering, coupling devices, cargo securement, driver credentials, hours-of-service records, and hazardous materials documentation where applicable.
What happens if a truck is placed out of service during Roadcheck?
When a driver or vehicle is placed out of service during a CVSA Roadcheck inspection, the vehicle cannot continue operating until the violation is corrected and cleared. Depending on the nature of the violation, resolution can take anywhere from a few hours to multiple days. Any freight on that vehicle waits until the truck is cleared to move.
How does International Roadcheck affect shippers?
Shippers with freight moving during the Roadcheck window can experience delays if their carrier’s driver or vehicle is placed out of service. These delays occur with no advance warning and are not automatically rerouted. Shippers can reduce their exposure by building delivery window buffers, verifying freight documentation, flagging critical loads, and having early conversations with their carrier about Roadcheck preparation.
Does Roadcheck apply to private fleets?
Yes. CVSA inspectors do not differentiate between for-hire carriers and private fleet vehicles. Any commercial motor vehicle on the road during the Roadcheck window is subject to inspection under the same standards.
