After a DWI arrest in Missouri, many people focus on the criminal charge. But for most drivers, the most immediate consequence is what happens to their license. In Missouri, that outcome depends largely on one decision: whether you submitted to a breath or blood test, or refused.
At B Block Law LLC, we regularly explain this distinction to clients because it controls which legal filing applies and what happens next.
If You Submit to a Breath or Blood Test
If you take a chemical test and your blood alcohol concentration is .08% or higher, the Missouri Department of Revenue can take action against your license.
This is known as an administrative suspension.
Common consequences include:
A 30-day suspension, followed by
60 days of restricted driving, if certain requirements are met
This license action is separate from your criminal DWI case and begins quickly after arrest. Drivers have a limited window to request a hearing to challenge the suspension.
Even if your criminal case is still pending in court, the administrative process moves forward unless it is addressed properly and on time.
If You Refuse the Test
Refusing a breath or blood test triggers a different filing and usually different license consequences.
This is known as a license revocation for refusal.
A refusal can result in:
A one-year license revocation
No automatic restricted driving privileges
Stricter reinstatement requirements
Many drivers assume refusing the test avoids consequences. In reality, refusal cases often carry harsher license penalties, and the deadlines to challenge them are just as strict.
Why Deadlines Matter
In both situations—whether you blow or refuse—there are short deadlines to request a hearing with the Department of Revenue. Missing those deadlines can mean losing the opportunity to challenge the suspension or revocation altogether.
License consequences can begin before a criminal case is resolved, which is why early legal guidance matters.
Criminal Case vs. License Case
It’s important to understand:
A DWI criminal case is handled in court
A license suspension or revocation is handled administratively
These are two different proceedings, and the outcome of one does not automatically control the other.
