Three-Day CMV Inspection Blitz to Crackdown on Hours of Service and Lighting Violations

Greenbelt, MD – The Commercial Vehicle Safety Alliance (CVSA) today announced the dates and focus of this year’s three-day North American inspection blitz known as International Roadcheck.

This year’s 72-hour inspection blitz of commercial motor vehicles operating in the U.S., Mexico and Canada is set for Tuesday, May 4 through Thursday, May 6.


Inspectors will ensure the vehicle’s brake systems, cargo securement, coupling devices, driveline/driveshaft components, driver’s seat, exhaust systems, frames, fuel systems, lighting devices, steering mechanisms, suspensions, tires, van and open-top trailer bodies, wheels, rims, hubs and windshield wipers are compliant with regulations.

Also during an inspection, inspectors will check the driver’s operating credentials, hours-of-service (HOS) documentation, seat belt usage, and for alcohol and/or drug impairment.

A driver will be placed out of service if an inspector discovers driver-related out-of-service conditions.

Categories of Emphasis in 2021

Each year CVSA emphasizes specific categories of violations.

In 2021 inspectors will be focusing on two categories — driver operating requirements and vehicle mechanical fitness.

For the driver category, HOS will be highlighted, and for the vehicle category, inspectors will be paying special attention to lighting.


According to the Federal Motor Carrier Safety Administration, the lighting violation “lamps inoperable” was the number one vehicle violation in 2020, accounting for approximately 12.24% of all vehicle violations discovered.

During last year’s International Roadcheck, the top driver out-of-service violation category in North America was HOS, accounting for 34.7% of all driver out-of-service conditions.

NOTE: International Roadcheck is a CVSA program with participation by the Federal Motor Carrier Safety Administration, the Canadian Council of Motor Transport Administrators, Transport Canada, and Mexico’s Ministry of Communications and Transportation and its National Guard.
