I was stopped on the grounds of "straddling the fog line," was then administered three field sobriety tests, administered a PBT and was arrested for DUI. I witnessed the officer following my car for about 10 minutes before the officer initiated a traffic stop. In that time I know that I properly stayed in my lane while obeying all traffic laws, especially since I knew an officer was following me. If a dash-cam shows that my driving was not impaired, could the charges be dropped on the grounds of an illegal stop? Also how can I request police dash-cam footage without an attorney?
