Windshield cracks occur more frequently in the winter months, usually as a result of 1) extremely low temperatures and 2) tiny, barely visible chips in the glass.
In cold weather, your vehicle’s frame flexes at a different rate than the windshield glass, which creates stress on the glass and can cause even the smallest chips to turn into cracks. The cold also makes your windshield more brittle, a condition which can allow a crack to spread faster and longer. And chips and cracks can get larger when the cold windshield is heated suddenly by the defroster.
It’s vital to repair any chips in your auto glass before winter rolls around. The windshield protects you in the event of an accident by keeping you inside the vehicle and supporting the roof. Cracks and chips can render the windshield ineffective, putting you and your family at risk.
