Once I was behind a drunk driver and called 911, I told them where was and they asked me to keep them in site as I stayed on the phone with the dispatcher. As the cop got close to me they asked me to turn on my 4 way flashers so it was easier for them to find me. The cop came up behind me and turned his flashers on and the dispatcher told me to move over so the cop could pull behind the drunk. JUST as I was moving out of the way, the car quickly tried getting off at an exit (I assumed they spotted the cops lights) but they missed the road and drove through the grass and took out the HUUGE sign for the exit!!!

I must admit, it was kind of neat, I felt like I was some cop show.
All I needed was the Bad Boys, Bad Boys what-cha gonna do.... playing in the back!!

Kimmy, I'm so glad he didn't hit you and that you had time to get out of his way. The way I look at it is that the police can't be everywhere all the time, and they can't see all the drunk drivers. So yes, I would call on a drunk driver. (again)
