Can You Drive on the Highway with a Cracked Windshield?
2 Answers
You cannot drive on the highway with a cracked windshield. The front windshield of a car is made of laminated glass, which can develop cracks when subjected to external impact. Air can enter the glass layers through the crack, potentially causing the layers to separate. If you continue driving, the pressure on the windshield will increase with changes in vehicle speed and wind speed, causing the crack to expand further. This not only affects visibility but also compromises driving safety. If the windshield crack is small, you can take it to a professional glass repair shop for fixing and drive only after the repair is completed. If you must drive due to time constraints, it is recommended to keep the speed below 100 km/h. If the crack is long, it is advised not to continue driving, and the windshield should be replaced promptly as it cannot be repaired.
I've been driving for over a decade, and you absolutely cannot take a cracked windshield on the highway. At high speeds, the wind pressure is intense, and a small crack can quickly turn into a large gap. Not only does it blur your vision, but there's also the risk of shattered glass flying around—it's extremely dangerous. Once, during a business trip, I faced a similar situation and had to slow down, pull over, and call for help, which cost me unnecessary money and wasted time. If the crack is small, it can be repaired by filling it with special adhesive; if it's large, you'll need to replace the entire windshield. I suggest you not take the risk—get it checked by a professional shop first. Safety is the top priority; don't gamble with your life. Also, avoid parking in direct sunlight or hitting the windshield to prevent the crack from expanding.
