Have you ever been driving peacefully on the road and suddenly heard a 'crack!' from a flying stone hitting your windshield? If it didn't leave a sharp crack, you're lucky. If it left a sharp, jagged crack, it's bad luck.
 
Prevention methods [If the glass is already cracked] Do not immediately blast the coldest air conditioning onto the car glass, because slightly cracked glass cannot withstand rapid temperature changes, which can lead to larger cracks. Andavoid driving behind or near trucks carrying construction materials such as stones, gravel, sand, or steel without covers. If unavoidable, find an opportunity to overtake them and keep your distance. Or if an unforeseen event happens and you get hit directly, what should you do? Let's find out, just in case you hit the jackpot during a long trip>

1. Stay calm, control the car, and reduce speed. Turn on emergency lights to signal other cars to be cautious, and slowly drive to the side of the road to find a safe place to stop. Do not force yourself to continue driving as it may cause danger. 

2. In cases where the glass is so cracked that you cannot see, and cannot ask for help from others, it is necessary to remove the glass. Use a cloth or a rubber mat to cover the dashboard, car floor, and hood area to easily collect glass shards and prevent the car from being scratched by glass fragments. 

3. Use a stick or hard material to push out the cracked glass. Push the glass from the outside of the car to prevent glass shards from hitting you (remove it completely). 

4. Use a damp cloth to wipe up fallen glass shards. Absolutely do not use your bare hands to pick up or brush them away directly. 

5. If you must continue driving, drive slowly and wear glasses to help protect your eyes from glass shards, dirt, and stones from other cars. Try to find a standard glass repair shop [If your car has insurance, you can claim it with your insurance]

[If a side window breaks] Lower the window glass to reduce vibrations that could cause more glass to fall. Even if the broken glass has spiderweb-like cracks, drivers must exercise increased caution and should take the car to a standard glass shop to replace the broken glass or repair the cracks on the glass as soon as possible to prevent further cracking, which could endanger the driver and passengers.
