Officer approached vehicle (I'm alone) after I was asked to pull to side of road. He said he smelled alcohol. He asked me to take a voluntary field sobriety test so he would know I was OK to drive. I told him I was OK. He asked again and I told him I was OK. He then said it's either yes or no? I said I'm OK and am I free to go. The officer said no and immediately opened my door, unbuckled my seat belt and pull me out of the vehicle handcuffed me as several other officers rushed over. The officer said if I moved he would taser me. Several officers begin to search my vehicle as he was moving me to the back of the patrol car. Another officer began to check my license and everything (license,insurance,registration) was good. I was never asked to exit vehicle or if they could search vehicle.
