How Long Can You Drive with a Cracked Windshield?
2 Answers
The cracked windshield can still be driven, but there is no exact time for how long it can last. The functions of the windshield: The car's windshield can reduce the interference and generation of crosswinds; it can also prevent raindrops, dust, and other small particles from entering the car; it provides a survival space for passengers. When impacted and shattered, the glass breaks into small pieces with blunt edges, minimizing harm to the occupants. Maintenance of the car windshield: Proper use of windshield washer fluid—in daily maintenance, choose the appropriate windshield washer fluid based on the season and weather; applying window film—as the weather warms up, the role of windshield film becomes particularly evident, not only protecting against summer sunlight but also providing heat insulation and UV protection; obtaining glass insurance—glass breakage insurance means that the insurance company is responsible for compensating for losses due to broken car glass during the use of the insured vehicle. In case of car glass breakage, a separate commercial insurance can be purchased. Glass breakage refers to the complete damage of only the windshield and window glass (excluding headlights and rearview mirror glass) of the insured vehicle.
I've driven for many years and seen plenty of cracked windshields. How long it lasts depends entirely on the size and location of the crack. Small cracks might hold for days or weeks, especially with stable weather and minimal temperature fluctuations. But I remember one summer driving on the highway under scorching sun—the crack spread within half an hour. Location is crucial too—if it's directly in the driver's line of sight, blurred vision becomes a safety hazard; cracks near the edges are less critical, but rough roads or sudden braking can cause instant shattering. I recommend checking the crack daily—if it expands, stop driving immediately. Temporary fixes like tape can help, but it's best to drive short distances at low speed to a repair shop for replacement. Don't delay more than a week to avoid accidents. Safety always comes first—a cracked windshield is no small matter.
