Sobriety checkpoints are police stops, or checkpoints, where officers are set up on a roadway to randomly stop vehicles to check for impaired drivers. These are usually set up during times when impaired driving is known to happen, such as holiday weekends.

Due to legal issues surrounding their use, not all states conduct sobriety checkpoints. Some states have laws authorizing their use. Although the U.S. Supreme Court has found sobriety checkpoints to be constitutionally permissible, ten states, Idaho, Iowa, Michigan, Minnesota, Oregon, Rhode Island, Texas, Washington, Wisconsin, and Wyoming have found that sobriety roadblocks violate their own state constitutions or have outlawed them.
