A bill for an act relating to the operation of an all-terrain vehicle modified to carry an additional person as a passenger.

HF 540 amends Iowa law to allow operating an all-terrain vehicle (ATV) with one additional passenger, beyond its original design, if the ATV has a commercially sold aftermarket or original equipment modification specifically designed for that ATV model to carry a passenger. This exception applies to non-farm operations, unlike the current rule which only permits extra passengers during farm activities. The modification must be manufactured for sale and designed to safely carry a passenger on that specific ATV type. The bill does not change the existing $135 fine for operating an ATV with more passengers than designed without meeting these criteria.
