What Should You Do If You're Stopped at a DWI Checkpoint?
The odds are that at least once in every driver’s lifetime they will encounter a DWI checkpoint. These checkpoints are randomly placed on main roads in the St. Louis and St. Charles counties, oftentimes around holidays or later at night. Typically, law enforcement makes several arrests for DWI while conducting these checkpoints. However, there are a variety of legal issues associated with these checkpoints.
If you’re stopped at a checkpoint, remember your rights. You’ll need to provide your driver’s license, registration, and proof of insurance. Beyond that, you don’t have to answer additional questions. Field sobriety tests can be refused, but refusing a chemical test such as a breathalyzer can trigger immediate penalties, including a suspended driver’s license.
If you have been arrested for DWI at a sobriety checkpoint, it is important that you immediately speak with an attorney who understands the legal issues associated with them.
Legality & Procedural Guidelines
What Happens During DWI Checkpoints in St. Charles, MO?
DWI checkpoints are legal in Missouri and are authorized under both federal rulings and state standards. However, to be constitutionally valid, they must meet key procedural requirements. Despite the fact that you haven’t done anything wrong, a police officer will likely approach your car and begin speaking with you. The officer will typically ask questions concerning how much alcohol you have been drinking, where you are coming from and where you are going.
Throughout this conversation, the officer is really observing your behavior while noting any signs of intoxication. You are being investigated for driving while intoxicated even though you technically didn’t do anything besides being in the wrong place at the wrong time. The nature of this investigation brings up numerous legal issues.
- Public notification: Checkpoints must be announced in advance to discourage drunk driving.
- Neutral stopping criteria: Vehicles must be stopped based on a predetermined, impartial pattern (e.g., every third vehicle).
- Supervision and planning: Senior officers must oversee checkpoint operations.
- Location & timing rationale: The checkpoint's placement should be supported by DUI-related data (areas with high incidences of impaired driving).
