DUI checkpoints, also known as sobriety checkpoints or roadblocks, are temporary traffic stops set up by law enforcement agencies to detect and deter impaired driving. These checkpoints are typically established in locations where impaired driving is known to occur or during times when there is a higher likelihood of impaired drivers on the road, such as holidays or weekends. At a DUI checkpoint, law enforcement officers stop vehicles at random or in a predetermined pattern to assess drivers for signs of impairment. This assessment may involve observing the driver’s behavior, administering field sobriety tests, and conducting breathalyzer tests to measure blood alcohol concentration. The primary goal of DUI checkpoints is to remove impaired drivers from the road, thereby reducing the risk of accidents, injuries, and fatalities caused by drunk driving.
