Special / superload review
Superload: a load or a vehicle transporting a nondivisible load that exceeds a gross weight of 150,000 lb, or in which any group or groups of axles exceed the limitations prescribed in K.A.R. 36-1-37. Large structure: any load that exceeds either 16 ft 6 in in width or 18 ft in height.

Definitions used throughout KDOT's escort-vehicle article.

State permit fee
Permit fees are fixed by statute at K.S.A. 8-1911(f) and are payable to the secretary of transportation; no distance, weight-excess or axle-count multiplier appears in the statute. KDOT also publishes a permit price list through K-TRIPS. Statutory fee schedule.

Escorts & markings
Pilot cars / escorts
Superloads, large structures, and loads exceeding 14 ft in width require escort vehicles. All escort service providers and operators must be registered with KDOT.

This is the Kansas Highway Patrol's own published summary of when escorts are required, with its statutory and regulatory citation. It does NOT state how many escorts, or their front/rear position by road class - that detail is in K.A.R. 36-1-36 (Common requirements), which could not be retrieved from an official source (see the 'validity' note).

Local / toll jurisdictions
The state permit does not cover local roads. The secretary issues permits for highways under the secretary's jurisdiction and local authorities for highways under theirs. Where a local authority chooses not to exercise that power, no local permit is required on its roads. State highways, secretary-designated connecting links and interstate highways are under the secretary's jurisdiction, not the local authority's.
