This document discusses challenging the validity of a DWI stop and arrest. It lists several factors to consider, such as whether the officer had reasonable cause for the initial stop based on evidence like dashcam footage, whether field sobriety tests were conducted properly, and whether the police report merely cites generic indicators of intoxication. It also notes that an individual must be given adequate opportunity to contact an attorney before chemical testing. Finally, it outlines that the prosecution must prove beyond reasonable doubt that objective probable cause existed for the arrest and test request.
