Why Truckers Dread International Roadcheck—and the Strategy Behind It

The ‘ingenious strategy’ behind most truckers’ least favorite week of the year: International Roadcheck

International Roadcheck Week is one of the most disruptive periods on the trucking calendar. For three days, inspectors across the United States, Canada and Mexico increase the number of commercial vehicles they inspect, creating delays at weigh stations and roadside inspection locations and prompting some drivers to stay off the road altogether.

The inspection blitz is unpopular with many drivers, but research by Andrew Balthrop of the University of Arkansas’ Sam M. Walton College of Business and Alex Scott of the University of Tennessee suggests that it produces a broader safety benefit. Their analysis found that trucks had fewer vehicle violations for roughly a month before and after the event.

That result is notable because Roadcheck is announced in advance. Inspections are usually more effective when they are unexpected, since advance notice gives people an opportunity to avoid them. In the case of International Roadcheck, however, the announcement appears to encourage many carriers to repair equipment and pay closer attention to compliance before inspectors arrive.

What happens during Roadcheck

International Roadcheck is organized through the Commercial Vehicle Safety Alliance, which brings together enforcement agencies in the United States, Canada and Mexico under a common inspection framework. The program generally takes place on a Tuesday, Wednesday and Thursday during the first week of June.

Inspectors commonly conduct Level One, or North American Standard, inspections. Those inspections cover both the driver and the vehicle. Inspectors review items such as hours-of-service records, licensing and medical qualifications, then examine the truck and trailer, including components that require them to go underneath the vehicle.

A typical inspection takes about 30 minutes. Approximately 60,000 inspections may be conducted during the three-day event, or about 20,000 per day. That volume can cause congestion at inspection sites, particularly when inspectors increase the number of trucks being selected.

Drivers are not guaranteed to be inspected, even during Roadcheck. There are millions of trucks operating on a typical day, so most will not undergo an inspection during the blitz. However, the likelihood is higher than during an ordinary period. A truck with little recent inspection history, or one with a poor recent inspection, may be more likely to be selected.

In 2021, 16.5% of inspected vehicles were placed out of service, along with 5.3% of drivers. A vehicle or driver placed out of service cannot continue operating until the relevant violation is corrected.

Why advance notice can improve compliance

Balthrop described the advance notice as an unusual but effective enforcement strategy. Inspections are relatively infrequent for many drivers. Over the course of a year, roughly 2 million inspections may be conducted among an estimated 3 million to 4 million trucks, meaning some drivers can go years without a detailed inspection.

With enforcement occurring infrequently, the threat of a routine inspection may not be enough to influence daily behavior. Roadcheck changes that calculation by concentrating inspections into a short, highly visible period.

Carriers and drivers often prepare in advance. They may arrange a private inspection, schedule maintenance or correct equipment problems before the blitz begins. Drivers also tend to pay closer attention to hours-of-service requirements and other operating rules.

The researchers found a 1.8% reduction in vehicle violations in the month before and the month after the inspection period. Vehicle-related improvements lasted longer than the event itself, suggesting that the maintenance work completed in preparation for Roadcheck can continue to benefit safety after the inspection teams leave.

By contrast, surprise inspection events did not produce the same increase in compliance, according to the research. The advance warning appears to be an important part of the program’s effect.

Small carriers are more likely to stay home

The drawback is that some operators can avoid the inspection period entirely. Balthrop and Scott found that about 5% fewer one-truck carriers were active during Roadcheck than on comparable days. The effect was strongest among owner-operators and carriers with older equipment.

A single-truck business can schedule vacation, maintenance or other time off during the three-day event. Larger fleets generally do not have the same flexibility. A carrier with hundreds or thousands of trucks cannot simply stop operating for several days, so it is more likely to keep running while emphasizing preparation and maintenance.

The difference is also reflected in equipment age. Older trucks are often more expensive to maintain and have had more time to develop mechanical problems. Those trucks were more likely to be absent from the road during Roadcheck, according to the research.

Inspection selection is not entirely random. Inspectors can select a truck after observing an apparent defect or another violation. Electronic inspection-selection systems also consider a carrier’s inspection history. A carrier that has not been inspected recently may be more likely to be selected, while a carrier with a denser inspection record may be less likely.

The safety and cost tradeoff

The inspections impose real costs on the trucking industry. Drivers lose time, inspection sites can back up, and carriers spend money on repairs, maintenance and private inspections. A private inspection may cost approximately $100 to $120, and applying that figure to 60,000 inspections produces a rough cost of more than $10 million.

That estimate does not include all compliance, delay and enforcement costs. Still, Balthrop said the program could justify those expenses if it prevents even a small number of serious crashes.

Vehicle condition is a significant safety concern. Federal data cited in the research indicate that brake problems are a major factor in 29% of truck crashes. Identifying a defective brake system or another serious mechanical problem before a truck reaches a crash situation can have consequences well beyond the inspection site.

International Roadcheck is generally held in warmer months because winter conditions make roadside inspections more difficult and reduce inspector productivity. Other enforcement campaigns focus on brakes or driver behavior at different times of the year, but there is no comparable high-intensity inspection event during winter.

For drivers, Roadcheck remains an inconvenience—and for some, a reason to schedule time off. But the research indicates that the inconvenience may also serve a larger purpose: a short, highly visible inspection period can encourage better equipment maintenance and compliance well beyond the three days when inspectors are out in force.
