Inspection Blitz Across North America Set to Begin… Here’s What Inspectors Will Be Looking For

Greenbelt, MD — The Commercial Vehicle Safety Alliance (CVSA) is gearing up for International Roadcheck, its annual 72-hour North American inspection blitz.

Scheduled for Tuesday, May 17 through Thursday, May 19, commercial motor vehicle (CMV) operators can expect inspectors in Canada, Mexico and the U.S. to conduct North American Standard Inspections at weigh and inspection stations, on roving patrols, and at temporary inspection sites.


This year’s International Roadcheck will focus on wheel ends, which include the wheels, rims, hubs and tires.

According to CVSA, violations involving these components historically account for about one quarter of the vehicle out-of-service (OOS) violations discovered during the three-day blitz.


Here is a rundown on what you can expect inspectors to be looking for during this year’s initiative:

• Check for cracks or unseated locking rings, studs or clamps.
• Check for bent, cracked or broken rims on the inside and outside wheel rims.
• Check for loose, broken, missing or damaged wheel fasteners and elongated stud holes.
• Check spoke wheels for cracks across spokes and in the web area or slippage in the clamp areas.
• Check the hub for lubricant leaks, missing caps or plugs.


• Check the inner wheel seal for leaks.
• Check the tire and valve stem for leaks.
• Check for proper inflation, cuts and bulges on all tires, including the inside tire on a dual set.
• Check for regrooved tires on steering axle.
• Check tread wear and measure major tread groove depth.
• Inspect the sidewall for improper repairs, such as tire plugs.


• Check for exposed fabric or cord.
• Check for tire contact with any part of the vehicle.
• Check for markings on the tire that would exclude its use on a steering axle.
• Check for debris between the tires.
• Check for tires touching one another or any part of the vehicle.
