When you see a crack in your windshield, don’t panic! There are things you can do (and things you shouldn’t do!) to prevent it from getting worse:

Windshield Crack DO’s

Measure the crack: If it is less than 12 inches long or smaller than the size of a quarter, the damage can be repaired rather than having to replace the entire windshield.

Check the location of the crack: If it is in your line of vision while driving, you should get it fixed before driving anywhere.

Protect the damage from dirt: Dirt, dust and other particles getting into the crack will make it more difficult to repair. Cover the crack with a piece of clear tape.

Keep your car out of the sun: Built-up heat may weaken the windshield and cause the chip to grow and spread.

Contact an auto glass provider.

Windshield Crack DON’Ts

Ignore the issue: Small cracks and chips will spread if not repaired, and may result in eventually needing a replacement. Larger cracks can also affect your visibility while driving.

Crank up the air conditioner or defroster: Extreme temperatures may compromise the integrity of the windshield.

Wash the vehicle: If water gets into the damaged area, it can cause the crack to spread.

Repair cracks larger than 12 inches or the size of a quarter: This extent of damage is cause for replacement.

Take your car to a general mechanic: Choose an experienced auto glass specialist.
