Is a small chip in the windshield caused by a stone a serious issue? A small chip in the windshield caused by a stone is not a serious issue. Here is some relevant information: Function of tempered glass: Tempered glass is made by quenching ordinary glass to create internal stresses, thereby strengthening the glass. When impacted and shattered, the glass breaks into small, blunt-edged fragments, reducing the risk of injury to passengers. Function of zone-tempered glass: Zone-tempered glass is a new type of tempered glass that undergoes special treatment. When impacted and cracked, it maintains a certain level of clarity in the cracks, ensuring the driver's field of vision remains unaffected. Currently, most car windshields are made of laminated tempered glass or laminated zone-tempered glass, which can withstand strong impacts.
When my car's windshield got a small chip from a rock, I initially thought it was nothing and kept driving for a few days. But later, I noticed it gradually grew larger. The reason is that there might be micro-cracks inside the chip, and factors like water pressure during car washes or temperature changes caused the cracks to slowly expand. The location is crucial—if the chip is directly in the driver's line of sight, not addressing it promptly could affect safe driving. Even chips on the sides can spread into cracks. Once during winter, a sudden cold snap turned the chip into a long crack, which startled me. The repair method is simple: find a professional glass shop to inject resin and fill the hole, costing less than 200 yuan with good results. My advice is not to overlook such small issues—safe driving is no trivial matter, and fixing it early brings peace of mind.
