DUI checkpoints (sobriety checkpoints) are legal in most states. Here's what you need to know about your rights.
States Where Checkpoints Are Illegal
12 states don't conduct DUI checkpoints: Alaska, Idaho, Iowa, Michigan, Minnesota, Montana, Oregon, Rhode Island, Texas, Washington, Wisconsin, and Wyoming.
Your Rights at a Checkpoint
You must stop and provide your license and registration. You do NOT have to answer questions about where you've been or whether you've been drinking. You can refuse field sobriety tests in most states.
Chemical Test Refusal
Refusing a breathalyzer or blood test triggers implied consent penalties (automatic license suspension) in all states, but the length of suspension varies.
Recording the Encounter
You generally have the right to record your interaction with police at a checkpoint, which can be valuable evidence for your defense.
