ID S1072

Authorizes the Idaho Transportation Department, Idaho State Police, and Idaho State Tax Commission to enter into joint exercise of powers agreements to implement dyed fuel inspection provisions.

Permits inspection of diesel-powered motor vehicles for dyed fuel when stopped at check stations or when lawfully detained by law enforcement, with inspections limited to the specific vehicle and not serving as probable cause for other vehicles.

Establishes that dye presence at 0.6 parts per million (PPM) or greater in licensed motor vehicles constitutes a violation, with a 3-month grace period for new owners of previously authorized dyed fuel vehicles.

Requires six months of outreach and education before inspections begin and exempts inspections during governor-declared emergencies or presidential disaster declarations when fuel is necessary for relief.

Sets civil penalties for dyed fuel violations: $250 for first violation, $500 for second, $1,000 for third, and up to $10,000 for subsequent violations, plus $1,000 penalty for refusing inspection; mandates legislative evaluation after five years.
