Obstructed windshields, cracked windshields, windshield replacement and other laws and regulations are different for every state. Cracked windshield laws in Iowa prohibit driving vehicles if 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. Despite this, federal regulations require any devices attached to windshields placed 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 are only permitted if they are not located within 3 inches of another crack.
Cracks and chips, or other damage which can potentially obstruct clear view of the road, must not be within critical vision area. This area is defined as area directly above the steering wheel, two inches from the top and one inch from sides.
