Can You Drive on the Highway with a Cracked Windshield?
2 Answers
Driving on the highway with a cracked windshield is not recommended. When the windshield is cracked, air can enter the glass interlayer through the crack, causing the interlayer to separate. Continuing to drive under such conditions means the windshield will endure increasing pressure due to changes in speed and wind velocity, leading to the expansion of the crack area. This can obscure the driver's view of the road, compromising driving safety. Precautions for a cracked windshield: If the crack is not severe, it can be repaired at a professional auto glass repair shop. Only after the repair is completed should the vehicle be driven on the road. If driving is urgent, the speed should not exceed 60 km/h, as higher speeds can exacerbate the crack, causing more severe damage.
Seeing a crack on the windshield and still wanting to drive on the highway, I think it's extremely dangerous, especially with the high wind pressure and speed on the highway, which can easily cause the crack to expand. A slight mistake could lead to the glass shattering, obstructing the view or directly causing an accident. I have a friend who once ignored a small crack and drove, only for the glass to shatter on the highway. Fortunately, no one was hurt, but they were fined a lot of money. Traffic regulations in many places explicitly state that vehicles with severely damaged windshields are not allowed on the highway, and violators may face fines or even have their vehicles impounded. If the crack is not too large, you can seek temporary repairs from a professional shop as a stopgap measure, but the fundamental solution is to replace the glass immediately. Otherwise, you're gambling with safety. The repair isn’t actually expensive, and some insurance companies even cover this service. Don’t delay and risk greater loss for a small gain. In short, safety comes first. It’s better to drive slowly in the city than to take risks on the highway.
