UT HB0011

Government officials may only inspect a vehicle's fuel tank for dyed diesel fuel violations if they have probable cause, owner consent, or are conducting the search at a port-of-entry under Section 72-9-501

Simply observing someone driving a diesel-powered vehicle on a highway does not constitute probable cause for a fuel tank inspection

Operating a vehicle with dyed diesel fuel on highways remains prohibited, with exceptions for agricultural travel between owned parcels and special mobile equipment used incidentally on highways for construction

First-offense penalties are the greater of $500 or $5 per gallon based on tank capacity; second and subsequent offenses are the greater of $1,000 or $10 per gallon
