 Hello, sir. How are you tonight? We are setting up a DUI checkpoint. Have you had any alcohol to drink at all? We have officers out here looking to identify an apprehend drivers under the influence of alcohol or drugs You'll come in contact with one of the officers the officers will conduct a quick investigation Do you mind if I check your eyes real fast? No sure. Go ahead. Are they observing any signs of impairment smelling alcohol the odor of burnt marijuana? You just had the one one joint right? If they reasonably suspect that there's something for them to investigate further they'll ask the driver to step out They'll run them through roadside maneuvers which is standard field sobriety testing If the subject doesn't perform those as a reasonably sober person would the officer would have them choose between taking a blood test or a breath test I just need to make sure that you haven't been drinking this evening If you're going to consume alcoholic beverages you get behind the wheel of a car Or you're going to smoke marijuana or take prescription drugs you could potentially be arrested
