Don’t they typically do field sobriety tests before breath tests?
Not necessarily. I think the field test is also used to determine capacity to continue to drive. So, they might use it after an acceptable blow test just to get their way AND to have court data supporting their decision. I don’t really fault the police on drunk drivers. Impaired drivers are deadly. I fault some of them for being rude and arrogant even when their numbers don’t validate their suspicions.
