What vehicles must stop at weigh stations?

If your vehicle meets the definition of a commercial motor vehicle (over 10,000 lbs., buses, limousines, or any size vehicle hauling haz-mat that requires placards), you must stop at the weigh station if it is open. 

While some of the regulatory signs read all “TRUCKS” must stop, the weigh stations are designed to weigh and inspect commercial motor vehicles.  If your vehicle meets the definition of a commercial motor vehicle (over 10,000 lbs., buses, limousines, or any size vehicle hauling haz-mat that requires placards), you must stop at the weigh station if it is open.  If you are using PrePass or DriveWyze weigh station bypass services, follow the in-cab signals of those devices.  (KSA 8-1507, 8-1910, 66-1324)
