1. Keep Your View of the Road Clear
If the crack appears while you are driving, stay focused on traffic and avoid sudden maneuvers. If the damage interferes with your view or loose glass is present, move to a safe place when you can do so without creating another hazard.
2. Inspect the Damage From a Safe Location
Once parked, look at the size and location of the break. A small chip is different from a long edge crack or a windshield with multiple impact points. Do not press on the glass to test it.
3. Keep Dirt and Moisture Out of a Small Chip
If the damage is a small chip and the surface is dry, a small piece of clear tape can temporarily help keep contamination out without blocking visibility. Do not fill the chip with glue, nail polish or other household products.
4. Avoid Rapid Temperature Changes
Do not blast a very cold windshield with maximum defroster heat or pour hot water on cold glass. Glass expands and contracts with temperature, and sudden changes can increase stress around a damaged area.
5. Schedule an Assessment Promptly
Small damage is generally more likely to remain repairable when it is addressed early. A provider can determine whether resin repair is appropriate or replacement is the better option.
Repair or Replacement?
Repairability depends on the damage size, depth, location and windshield construction. Long cracks, edge cracks, deep damage and cracks in critical viewing areas are more likely to require replacement. Newer vehicles can also have cameras or sensors that need special consideration.
