DUI checkpoints, also known as sobriety checkpoints, are locations where law enforcement officers stop vehicles to check for drivers under the influence of alcohol or drugs. These checkpoints are typically set up during times when impaired driving is more common, such as holidays or weekends. Officers may ask drivers to provide identification and may conduct field sobriety tests if they suspect impairment. The primary goal of DUI checkpoints is to deter impaired driving and enhance road safety. They are usually announced in advance through public notices, and their legality varies by state. Officers at these checkpoints follow specific protocols to ensure fairness and minimize inconvenience to drivers.
