Is it necessary to replace a cracked windshield?

It is necessary to replace a cracked windshield. The specific reasons are as follows: The crack may enlarge: Cracks can continue to expand due to factors such as temperature changes, high-speed driving, and road bumps. Affects the driver's vision: It is more likely to threaten the safety of the vehicle's occupants. Relevant information about car windshields is as follows: Windshield: Refers to the glass component of a car that blocks wind. Function: The "cleanliness" of the car windshield can determine the clarity of the driver's vision; the quality of the car windshield is closely related to the driver's safety. Below is related information about car glass: The development of modern car designs is closely related to advancements in glass technology. As early as 40 years ago, car front windshields began using single-piece curved windshields, gradually abandoning flat-type windshields. Today's car windshields are generally made into large curved single-piece designs, with certain curvatures on all sides. This type of curved glass, whether from the processing or assembly perspective, is a product that requires very high technical standards, as it involves issues such as vehicle model, strength, heat insulation, and assembly.
The most frightening thing while driving is having issues with the windshield. I once experienced a situation where a small stone hit the front windshield, causing a crack. At the time, it seemed minor, so I ignored it. Later, during hot weather, I suddenly noticed the crack had spread horizontally across half the glass. Actually, windshields are made of double-layered laminated glass; even if the outer layer cracks, the inner layer can still hold up, but it poses significant safety risks. First, the crack can reflect light and obstruct vision, especially dangerous when driving at night. Second, the strength of the glass decreases, and in the event of a collision, it might shatter entirely. Third, the probability of leaks—both water and air—increases. I specifically consulted a friend at an auto repair shop, and they said if the crack exceeds the size of a credit card or reaches the edge of the glass, it’s basically time for a replacement. Looking back now, safety is definitely not something to compromise on.
