Regardless of whether or not a glass of your adult beverage of choice was had at dinner, pulling up to a DUI checkpoint can be stressful. There are several things to know before driving through in order to make sure your rights are being protected. First, all DUI checkpoints must be established by supervisory personnel and given adequate procedure – meaning officers cannot set up checkpoints based on their own discretion. Next, the stops must be standardized and cannot be made randomly. The checkpoint should also display adequate safety precautions such as proper lighting, warning signs, and signals. In the state of Missouri, however, finding that a checkpoint did not give officers any discretion was enough to establish that the checkpoint was valid.
