Obstructed windshields, cracked windshields, windshield replacement and other laws and regulations are different for every state. Cracked windshield laws in Illinois prohibit driving vehicles where driver’s view of the road is obstructed.
Can I drive with a cracked windshield in Illinois?
Illinois laws mention cracks on windshields, but do not provide detailed information about the size of cracks or chips allowed. Drivers are not permitted to operate vehicles with windshields in defective condition which impairs clear view of the road, therefore it is up to individual police officers to determine if your view is impaired.
Other laws and regulations:
- Obstructed windshield regulations: No sign, poster, or other non-transparent material that obstructs visibility is permitted.
- Replacement windshields: Replacement windshield glass must be of the same kind and quality, and any repairs should restore vehicle to its original state.
- Windshield wipers: Vehicles must be equipped with windshield wipers in good working conditions. Cracks which prevent wipers from operating correctly may be illegal.
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.
