What are the white spots that appear on the windshield at high speeds?

[StCollin]

White spots that appear on the windshield at high speeds are caused by a mixture of rainwater and dust or small stone chips. Solutions for white spots on the windshield: For the mixture of rainwater and dust, use a bucket and towel with water or detergent to clean it promptly. For white spots caused by stone chips, you can go to a repair shop or vehicle detailing center to apply a layer of paint matching the glass color. Precautions for high-speed driving: Check the vehicle condition before driving, fasten the seat belt, and appropriately increase the speed to 60-70km/h at the junction of the ramp and the highway before officially entering the highway. Do not decelerate easily on the highway, and maintain a reasonable distance from the vehicle in front to ensure the safety of both vehicles.

When driving on the highway, those small white spots that suddenly appear on the windshield—I've encountered them several times myself. They're usually caused by small stones or other debris flying up from the road and hitting the glass. At high speeds, stones are more likely to be kicked up and strike the windshield. These white spots are small dents or pits, often referred to as "pit marks." If left untreated, they can gradually expand and impair visibility during rain or at night. The first time I noticed them, I was quite concerned, but I later visited a professional auto glass shop. The technician fixed it quickly and affordably using resin. I recommend maintaining a safe distance from the vehicle ahead on the highway to reduce the chance of debris being kicked up. Also, try to park in a safe spot to avoid tree sap or bird droppings, which can cause similar issues—safety always comes first. Just sharing my experience—if you encounter this, don’t panic, and get it fixed promptly.

From a maintenance perspective, white spots appearing on the windshield during high-speed driving are most commonly caused by road gravel or debris being kicked up by tires and impacting the glass, creating tiny pits that appear as white spots. These are essentially surface damage to the glass. Over time, rainwater or dirt entering these pits may expand the cracks, affecting visibility and potentially leading to larger fractures. It's advisable to first check if the damage is superficial. If shallow, DIY repair kits can be used, but for severe damage, professional repair with resin or UV-curing technology is more reliable. Preventive measures include installing stone guards, regular glass cleaning, and maintaining a greater following distance to avoid debris impacts. Though small, these spots pose cumulative risks at high speeds—never overlook safety details.

When I first learned to drive on the highway, I noticed small white dots on the windshield and got really nervous, thinking it was some major issue. Later, I asked a friend and learned that these are minor dents caused by pebbles or debris hitting the glass at high speeds, which don’t immediately affect visibility. If the dots are very small and don’t obstruct your view, you can leave them alone for now. But if they’re large or numerous, you should get them repaired at a shop as soon as possible. Actually, it’s quite common and not a serious malfunction—just stay calm and keep driving. New drivers shouldn’t worry; learning some basic knowledge helps a lot, and regularly checking your car’s condition can prevent bigger problems.
