About FMCSA inspection stations
FMCSA inspection stations — sometimes called weigh stations, scales, or ports of entry — are the physical points where state law-enforcement officers stop commercial motor vehicles to conduct safety inspections, weight checks, and credential verification. The federal Motor Carrier Safety Assistance Program (MCSAP) funds the inspector workforce; the Commercial Vehicle Safety Alliance (CVSA) defines the inspection-level standards (Levels I through VI). Every report becomes part of FMCSA's national inspection file, which is what TruckCodex mirrors here.
A station's "OOS rate" — out-of-service rate — measures the share of inspections that ended with the vehicle, driver, or both placed out of service. A high OOS rate doesn't necessarily mean the inspectors are stricter; more often it reflects the population of carriers passing through the corridor. A low OOS rate often means the station is on a route used by larger, well-maintained fleets running regular pre-trip programs.
TruckCodex is not affiliated with the FMCSA, MCSAP, CVSA, or any state DOT. Every station record on this site is sourced from the public FMCSA inspection file and refreshed daily. We do not publish staffed hours, schedule changes, or upcoming enforcement details — those would not be public to begin with. For the live status of any specific station, contact the operating state's commercial-vehicle enforcement bureau.
