The windshield is the number one safety restraint in your vehicle. So it’s important to repair any minor damage before a full replacement is necessary, to keep yourself and your passengers safe. If you have a small crack or chip in your windshield, make sure to have it repaired as soon as possible, before it becomes an unrepairable crack. Even the most advanced glass repair techniques have their limits. if your windshield is severely damaged, a full replacement may be in your future. Ask your service advisor at Lowe's Automotive Service Inc to have your windshield checked for any cracks or chips that can still be repaired. Cracks and chips can severely impact your ability to see the road, and may compromise the overall safety of your vehicle. From a safety standpoint, there is a large safety risk, because a crack in the windshield will limit its ability to protect you. But on the other hand, there is no environmental impact of windshield repair.
