I was charged with a DUI and a greater than .15 alcohol percentage. I never received a "traffic enforcement stop" but rather, I had already been stopped on the side of the freeway when the officer approached behind us. Officers report stated that he pulled over because he noticed a passenger leaning out and vomiting from the vehicle and wanted to inquire whether we needed assistance. Officer smelled alcohol and administered field test and breathalyzer. However, after watching the M.V.A.R.S (video/audio) from the patrol vehicle, it is apparent that the officer had approached our vehicle before any passenger had opened their door. It seemed the officer had intentions to pull me over, but because I had already pulled over, a traffic enforcement stop was not necessary.
