(4) Authorized employees of the transportation department may stop any vehicle with a maximum gross weight of eighteen thousand (18,000) pounds or more by displaying a flashing red light if the authorized employee has probable cause to believe the vehicle bypassed a weighing or inspection station or proceeded through the station without regard for the directional signals. Authorized employees may direct a vehicle that has bypassed a weighing or inspection station, or has proceeded through the station without regard for the directional signals, to return to the bypassed inspection or weighing station and may issue a citation for failure to stop as required in this section. The operator of a vehicle shall bring the vehicle to a stop, pulling off the traveled portion of the highway, when directed to do so by an authorized employee of the transportation department by use of emergency lights or siren.

(5) The department is authorized to implement technology and procedures, where practicable, to allow vehicles that meet established criteria to lawfully bypass a port of entry. The department may promulgate rules to implement the provisions of this section.
