Discription of Events: This driver was following the other driver of a black Acura extremely close from Double Bridge Rd onto Hwy 42. The Acura slowed down quickly and he swerved around in a non passing zone then slammed on brakes in front of the Acura. The driver then proceeded to drive slow and straddled two lanes so the Acura couldnt go around and flipped the driver off after turning on Fielder Rd.
