Transportation (Roads & Highways)

This bill (SSB 3132) sets a new enforcement standard for motor vehicle front windshields in Iowa, requiring a minimum of 50% light transmittance (down from the current 70% standard for visibility). Drivers operating vehicles with windshields below this 50% threshold face a citation and potential vehicle impoundment, though they may instead immediately fix the windshield to meet the 70% standard or tow the vehicle off the road. The bill prohibits operating an impounded vehicle until its windshield meets the 70% transmittance requirement, with a $70 fine for violations. It excludes law enforcement vehicles operated during official duties from these rules.

This bill modifies Iowa's rules for operating all-terrain vehicles (ATVs) on highways. It creates specific exceptions allowing ATVs for agricultural use (e.g., traveling between fields or stopping for fuel) and establishes detailed rules for safely crossing highways. Registered ATVs may operate on certain undivided primary/secondary roads and city streets under local designation, but must not exceed 35 mph and are prohibited on most highways unless meeting these exceptions. The bill directly affects ATV operators, farmers, counties, and cities responsible for road designations and enforcement.

HF 394 restricts the Department of Transportation from designating a segment of State Highway 5 and US Highway 65 as an interstate unless federal exemptions for vehicle weight and size are secured. It creates a temporary exception, allowing implements of husbandry to continue operating on a specific portion of this highway if it becomes an interstate, until a suitable alternative route is established. The bill appropriates $250,000 to the Department of Transportation to study and develop this alternative highway route for agricultural vehicles. These provisions directly affect the Department of Transportation's authority over highway designations and agricultural vehicle operators in the specified areas.
