Small cracks in the windshield can develop into major safety issues and compromise the structure of a vehicle, auto information site Edmunds.com warns.

Chips and cracks usually are not dangerous but over time rain can wash dirt and debris into the open space, making it harder to seal or fix. As a result, postponing action can make it impossible to fix later in unfortunate cases.

While most cracks and chips are minor, they can weaken the windshield so that it no longer serves its purpose. In addition to sealing the interior off from air and weather, the windshield is also a structural component that supports the roof.

If it is weakened or not installed correctly, is may fail to do so, and increase the chance of the roof being crushed inward on the vehicle's occupants during a crash, according to the source. It may even pop out of the frame. Safety precautions such as caring for a vehicle and ensuring proper auto insurance coverage must be seen to before they are needed, since once the time arrives it is too late to check repairs and buy coverage.
