I was driving down the road recently and I got hit in the windshield with a rock that was thrown from a pickup that didn’ t have any mud flaps.  It cracked the windshield and if I dont’ do something soon, I will not be able to save the windshield and will have to get a new one. I just bought Custom Mud Flaps for my truck within the last week.  They have my company name and website and  the company logo. It is great advertising since I needed new mud flaps anyway but they also will prevent rocks being thrown in someone Else’s window.
