DUI checkpoints, a.k.a. sobriety checkpoints, are handled on a state-by-state basis. Some jurisdictions allow them. Others do not. In other words, the constitutionality of DUI checkpoints is somewhat unsettled, at least on the national level.
DUI checkpoints significantly increase over the Christmas and New Year's holidays in Vista, Oceanside, Carlsbad, Encinitas and throughout California. These checkpoints not only result in helping to keep impaired drivers off the road by arresting them, but their mere existence also has a psychological effect on people deciding whether to drive after drinking. Many people will think twice about getting behind the wheel after drinking alcohol or using drugs for fear they might drive get stopped at a checkpoint. The costs of being arrested, vehicle towed, insurance, Court as well as the anxiety involved and possible impact on your future, far outweigh the inconveinence and minor expense of a taxi or other arrangement.
