St. Charles DUI/DWI Defense Lawyers Understanding The 15-Day Rule in Missouri

Navigating The 15-Day Administrative Hearing Rule

If you take a breath test that exceeds Missouri’s 0.08% legal limit, the officer will issue a notice that your license is being suspended for 90 days. This is an administrative action handled by the Department of Revenue (DOR), not a criminal penalty. You may request an administrative hearing to challenge the suspension and protect your driving privileges.

At Boehmer Law, you work with an experienced DWI lawyer who guides you through every step of the process. It is essential to understand the St. Charles 15‑day rule because you have a limited window to request your hearing and protect your license.

Criminal Court Vs. DOR Administrative Actions In Missouri

When you are arrested for DUI or DWI, you actually face two legal tracks. The criminal case moves through the courts and focuses on whether you violated state law. This process determines potential penalties such as fines, probation or jail time. It also involves hearings, negotiations and the possibility of taking your case to trial.

At the same time, the Missouri DOR begins an administrative action against your license. This civil process is triggered by either a failed breath test or a refusal. It operates on strict deadlines and can result in a suspension even if your criminal case is later reduced or dismissed. Understanding how these two systems interact is essential to protecting your record and your ability to drive.

What Is The 15-Day Rule After A Missouri DWI Arrest?

Under Missouri’s implied consent law, your license consequences begin when arrested or upon either failing or refusing a chemical test. An officer will issue the Notice of Suspension or Revocation, which starts the countdown. That notice serves as your temporary license. From the date it is issued, you have 15 days to make a request for an administrative hearing with the DOR.

What Happens At A Missouri DOR Administrative Hearing?

After you request a hearing, the DOR schedules it before a state-licensed attorney who works for the department. It takes place by phone or at a regional DOR location. The state has to prove two things:

• There were reasonable grounds to detain you for DWI
• Your BAC was at or above the statutory limit

Those are the only two issues on the table. If the state cannot prove either one, the suspension is canceled. If the DOR rules against you, the suspension holds and you have 15 days from the date of that written decision to appeal. You do that by formally requesting a trial de novo in the appropriate circuit court. A judge decides the case without a jury, and the state must prove its case all over again.

What If You Miss The 15-Day Deadline?

You lose your right to a hearing. Missouri courts have been clear: there are no exceptions to the 15-day rule. The DOR will deny any late request, and your license suspension takes effect automatically.

If it’s the first offense, you lose driving privileges for 30 days. After that, you get 60 days on a restricted license. If you have prior alcohol-related contacts on your record, the DOR will revoke your license for a full year with no restricted driving.

Frequently Asked Questions About The 15-Day Rule In Missouri

Here are answers to some questions our attorneys hear most often from drivers in St. Charles and the surrounding area.

Does the 15-day rule count calendar days or business days?

It counts calendar days. The 15-day clock starts the day the officer issues or serves a Notice of Suspension or Revocation (Form 4307). Weekends and holidays do not pause the clock. If you are unsure when the officer issued your notice, our DWI defense attorneys can review your paperwork and confirm the exact date.

What happens if I refuse the breath or blood test in St. Charles?

A refusal bypasses the DOR process entirely. Instead, you will need to challenge the revocation directly before the circuit court in the county where you were arrested. You have 30 days from the date of arrest to file, not 15.

The consequences are more severe as well. A refusal triggers a one-year revocation, rather than a 90-day suspension. On top of that, the prosecutor can use your refusal as evidence against you in the criminal DWI case.
