Video of an individual taking the field sobriety tests in a Massachusetts OUI arrests rarely exists as most Massachusetts police departments do not have cruiser video. This is surprising to most people that meet with me to discuss an OUI charge believe that the entire encounter will be on video of their OUI arrest. In fact this assumption is not true. Most police departments do not have cruiser video. The State police does not use cruiser camera and only a small fraction of local police departments have cruiser video. You are more likely to find a cruiser video in Worcester county than most of the other counties. While this is not an exhaustive list, the following police departments have cruiser video in at least some of their police cars.
