How to Avoid and Prevent Rock Chips
Rock chips and cracks on windshields are most common in areas of the world that use rocks to add traction to slippery roads. Most rock chips and small cracks can be repaired after, but it is still better to not obtain damage at all. Here are some tips on how to avoid rock chips in your windshield. Keeping a few simple tips in mind will help protect your windshield investment.
Distance
This one is simple, if you tailgate then more rocks will hit and chip your windshield. A larger space between you, and the vehicle in front of you, gives rocks more time to fall before you get there and is a great way to protect your glass. Not tailgating is a very good idea for other reasons as well.
Wheels
If two tires can kick up a rock and make you need a repair, four tires will do it twice as often. If you find yourself following or beside a vehicle with four rear tires, try to change lanes.
Mud Flaps
Vehicles with larger wheels usually have mud flaps. This is a requirement on semi and dump trucks for a very important reason. Large wheels not only throw more rocks but they also throw them further. However, not all vehicles that should have flaps do, and sometimes the flaps they have are ripped. Try to stay away from these, they will break your windshield! (Please note that not even mud flaps completely protect you).
