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.
This means it is up to individual police officer to determine if your view of the road is impaired.
Other laws and regulations:
- Obstructed windshield regulations: All signs, posters, or similar opaque materials which obstruct visibility are illegal.
- Replacement windshields: Replacement windshield glass must be of the same type and quality as original, and any repairs should restore vehicle to its original state.
- Windshield wipers: Vehicles must be equipped with windshield wipers in good working conditions. Cracks preventing wipers from operating correctly may be illegal.
Federal cracked windshield regulations
Federal laws require drivers to have a clear vision of the road. Windshield cracks or chips smaller than ¾-inch in diameter are permitted, however they must be at least 3 inches away from 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.
