If your windshield shatters when you are driving your car, it is important that you know what to do. When I was driving along the road one night, the rear window of my car suddenly smashed. I thought that someone may have thrown a rock at my car or that a stone had been kicked up from the road. I pulled over and called a mobile windshield repair service. The contractor was with me within an hour. He inspected my car and said he thought the window heater had malfunctioned and that this had caused the glass to shatter. Once he had replaced the glass, I continued my journey. I hope you find this blog useful.
