A crack could be triggered by washing a car with cold water during a sweltering day or by trying to defrost an icy windshield with hot water. Using a defroster or a car heater does not prevent this from happening either. Thermal expansion and contraction are one of the most common reasons for a cracked windshield.
What causes a windshield to crack on its own?
Stress and Pressure
Windshields are made of glass and plastic components, so naturally, they can only withstand so much pressure. Too much pressure applied in any one area of the windshield’s surface can be enough to cause cracks to form in or around that particular area.
Can a windshield shatter on its own?
While a windshield usually won’t fall in on itself or burst like a side window from actors like temperature or pressure, a crack can expand, splinter out, and shatter (typically) the outer layer of glass. It usually falls out in small shards.
How does a windshield get broken?
The cold weather will quickly cool the windshield’s surface temperature. Then, when you switch on the defroster to clear the windshield before you drive to work or you park the car in the sunlight, the uneven heating of the window adds stress to the weak spot which can rapidly turn into that dreaded crack.
How much does it cost to fix windshield crack?
Typical prices range from $60 to $100 for a single chip, and discounts may apply when fixing additional chips on the same windshield. Crack repair prices are similar, although fixing a longer crack may cost $125 or more.
What happens if you don’t fix a cracked windshield?
Though not an immediate danger, if the crack is large, near or touching the edge of the windshield, the glass may have to be replaced and driving the car is not recommended. Driving with a broken windshield should also be avoided whenever the damaged glass impairs the vision of the driver.
Is it illegal to drive around with a cracked windshield?
Also, no windshield cracks are allowed directly in driver’s line of sight. States are required to adhere to the federal regulations, but they have some leeway when writing their own laws. For this reason, most states mandate that windshields may not have any cracks or flaws that interfere with the driver’s view.
How can I temporarily fix a cracked windshield?
Use Super Glue or Nail Polish as a Temporary Fix
These household products should only be used to stop a windshield crack from spreading if the crack is small. Superglue: Very gently apply the glue in an even layer over the crack. Wait for it to completely dry before using your car.
Should you put tape on a cracked windshield?
Dirt that gets into a crack or chip can make it more difficult to repair. Placing a small piece of clear tape over the point of impact can help, but make sure that the tape doesn’t block your vision when you’re driving.
