Discription of Events: Driver was tailgating in heavy traffic, would get in other lane to pass but then cut over almost intentionally hitting a car so they have to slam on their brakes to allow room for the driver to cut them off. He did this to about 5-6 other vehicles where it looked like he was intentionally trying to run people off the road and tailgated where he was inches away from the car infront of him. This was on the Gene Snyder where he got off the Taylorsville Rd exit and went toward Taylorsville. Truck is rusted on the back bumper and license plate is bent where the county would be listed. Very dangerous driver! I should have called the police but I was in shock and scared!
