Can You Drive on the Highway with a Cracked Windshield Caused by a Stone?
1 Answers
It is not recommended to drive on the highway with a cracked windshield caused by a stone. On the highway, there are many vehicles, high speeds, and the possibility of more stones, which can easily pose a danger to the driver. For personal safety, it is advised to repair or replace the windshield before driving on the highway. Automotive windshields are generally made of laminated glass. When subjected to external impact, cracks can form, allowing air to enter the interlayer of the glass, which may cause the layers to separate. If you continue driving, the windshield will endure increasing pressure due to changes in speed and wind, causing the crack to expand further. This can impair visibility and compromise driving safety. Although there are no regulations prohibiting driving on the highway with a cracked windshield, it is still not recommended for safety reasons. Windshield cracks can be repaired, but not all cracks are repairable. Only cracks on the outermost layer of glass can be fixed. Generally, repairable crack types include star-shaped cracks and linear cracks. Smaller cracks are naturally easier to repair. If the crack diameter exceeds 20mm, the repair effect will be poor, and it is recommended to replace the windshield instead.
