Roadside inspections and enforcement weeks
Most carriers meet the compliance system at the side of the road. An inspector can look only at the driver's paperwork, only at the vehicle, or at both. The full driver-and-vehicle version is the one that produces the most violations, because it covers brakes, lights, tires, coupling devices, cargo securement, the log, the license and the medical card in one stop.
Once a year the Commercial Vehicle Safety Alliance runs International Roadcheck, a 72-hour stretch in which jurisdictions across North America put extra inspectors on the road. CVSA also schedules a separate brake-focused week and an Operation Safe Driver week aimed at driver behavior. The dates and the emphasis area are announced ahead of time, so there is no reason to be surprised by them. Put the announced dates on the dispatch calendar the day they are published.
Treat the week before any enforcement event as a maintenance week. Walk every unit with a brake gauge and a tire tread gauge, replace any cracked lens or dead marker lamp, check that every load-securement strap is in rated condition, and confirm each driver has a current medical card and a working ELD with its required instruction packet and blank paper logs in the cab. A truck that passes a full inspection with no critical violations usually receives a CVSA decal, and decaled units are generally waved through for the following few months.
Not every violation is equal. An out-of-service order means the truck or driver may not move until the problem is fixed. One out-of-service finding hurts far more than several minor paperwork citations, both on your safety record and in an underwriter's eyes.
How it affects your insurance
Underwriters compare your out-of-service percentages with national averages. A vehicle out-of-service rate well above average reads as deferred maintenance, which is a predictor of physical damage and liability claims. A run of clean inspections is one of the few pieces of good news a newer carrier can show.
