This status was returned with high confidence from the real-time WSDOT data feed. Do not assume clearance on any state highway corridor without checking route-specific conditions at the time of dispatch.

  • Local and county roads are not covered by this data source. Restriction status for non-state routes cannot be inferred from this feed.

Weight Limits

The API did not return specific weight reduction percentages, axle limits, or gross vehicle weight limits at the time of retrieval. Route-level weight limits must be verified directly through WSDOT resources or by contacting Commercial Vehicle Services before dispatch on any restricted corridor.

Effective Dates

Exemptions

No exemptions were specified in the current data returned by the API. Do not assume any vehicle type, commodity, or permit class is automatically exempt. Verify exemption eligibility through WSDOT permit channels before routing.

Penalties

No penalty information was returned by the API for the current active restriction. Operating in violation of posted truck restrictions on Washington state highways may result in citation, fines, or permit revocation. Confirm current enforcement posture with WSDOT Commercial Vehicle Services.
