When someone says "DUI enforcement," what is the first thing that comes to mind? For many it is the traditional DUI checkpoint, where officers stop passing vehicles at random and determine if there is reasonable suspicion of intoxication by alcohol or drugs. If so, the driver performs field sobriety tests. If those fail, a chemical test is requested.
DUI checkpoints aren't the only method of planned enforcement, however. If you've seen our regular checkpoint posts, you'll notice that both checkpoints and saturation patrols are listed. The latter is a different approach to the same problem. Instead of a stationary sobriety checkpoint, the same officers overload an area with patrol cars and stop drivers who show signs of intoxication or violate traffic laws. The same process is then used to evaluate sobriety.
