If you are suspected of being drunk at a DUI checkpoint, the police officer may ask you to pull over to the side for further evaluation. They will likely conduct a series of tests, such as a breathalyzer test or a field sobriety test, to determine your level of impairment. If you fail these tests or show signs of intoxication, you may be arrested for driving under the influence. It is important to remain calm and cooperative during this process, as resisting or refusing to comply with the officer’s instructions can result in additional charges.
