How to use station-level data
- Note the station's typical activity hours. Review the latest inspection dates on this page to gauge how often TONSINA is staffed. FMCSA does not publish official hours.
- Check what level of inspection typically happens here. The Inspection Level Breakdown shows what mix of CVSA Level I, II, III, IV, V, and VI inspections this site runs. Expect the level-mix at the next visit to look similar.
- Pre-trip against common roadside inspection items. Walk-around the tractor and trailer for brakes, lights, tires, coupling, and hours-of-service paperwork before entering a high-activity inspection corridor.
- Track your own inspection history at /usdot/{your-USDOT}/inspections/. After every inspection, confirm the report shows up on your USDOT profile within 30 days. Disputes (DataQs) must be filed against your own record, not the station's.

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 We do not publish staffed hours, schedule changes, or upcoming enforcement details — those would not be public to begin with.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.
