A bill for an act requiring the use of safety belts or safety harnesses by passengers of motor vehicles, and making penalties applicable.

This bill requires all passengers aged 18 and older in Iowa motor vehicles (except motorcycles and motorized bicycles) to wear a properly fastened seat belt or safety harness while the vehicle is moving. It expands the current law, which only applied to front seat occupants, to cover all adult passengers. Key exemptions include emergency vehicle passengers (except drivers), workers in vehicles moving under 25 mph, and those with disabilities using collapsible wheelchairs. Violations carry a $70 fine, and the bill removes an existing exemption allowing back-seat children to skip restraints if belts are occupied.
