Can a car with a cracked windshield drive on the highway?
3 Answers
It is not advisable to drive on the highway with a cracked car windshield for the following reasons: 1. Air may enter the glass interlayer, causing delamination; 2. High speeds increase the pressure on the windshield, which can expand the crack area, impair visibility, and compromise driving safety. Methods to maintain a car windshield include: 1. Using specialized or appropriate wiper blades and replacing them promptly; 2. Keeping the front windshield clean; 3. Using automotive-specific glass cleaner. The repair method for a cracked car windshield is: 1. Clean and wipe the area around the crack; 2. Use tape to outline the crack to define the repair area; 3. Use a grinding disc to remove the crack, then polish the glass with polishing compound to restore clarity.
To be honest, I've been driving for decades, and if your windshield has a crack, don’t rush onto the highway. At high speeds, the wind pressure is intense, and a small crack can instantly spread into a large one, directly obstructing your view. Last year, I saw a friend whose crack suddenly expanded on the highway, nearly causing an accident. This is no joke—a crack reduces the glass’s strength by half, and under emergency braking or bumps, the entire piece could shatter. Safety first—I recommend pulling over to a quiet stretch of road to inspect it first. If the crack is smaller than a coin, you can take it to a professional shop for resin repair, which takes just minutes. If it’s larger, you must replace the glass. Don’t forget, daily driving also requires caution against flying stones, and regular maintenance can prevent such issues.
Windshield cracked on the highway? Buddy, I advise against taking the risk. The high-speed wind pressure can easily cause the crack to spread, suddenly obscuring your view. One of my followers experienced this on the highway and had to pull over urgently. Do a quick test: dry the crack with a tissue and drip some water to see how fast it flows. Fast flow indicates internal structural damage, making highway driving risky. Small cracks can be repaired for just tens of dollars, while major issues may cost thousands to replace the entire windshield. Park in the shade to prolong glass lifespan. Use dashcam footage for repair shop comparisons.
