Obstructed windshields, cracked windshields, windshield replacement and other laws and regulations are different for every state. Cracked windshield laws in Iowa prohibit driving vehicles where driver’s view of the road is obstructed.
Can I drive with a cracked windshield in Iowa?
Iowa laws do not mention windshield cracks nor windshield obstruction. Federal regulations require that any devices attached to windshields be on uppermost 6 inches, and outside the area cleared by windshield wipers. Any stickers must also be outside wiper’s clearing area and must not obstruct or impair clear view of the road.
Other laws and regulations:
- Replacement windshields: Replacement windshield glass must be of the same kind and quality, and any repairs should restore vehicle to its original state.
Federal cracked windshield regulations
Federal regulations require drivers to have a clear vision of the road. Windshield cracks or chips smaller than ¾-inch in diameter are permitted if they are not located within 3″ of another crack.
Any cracks or chips or other damage which can potentially obstruct clear view of the road must not be within critical vision area, defined as area directly above the steering wheel, two inches from the top and one inch from sides.
