A first-time DWI is usually a misdemeanor, and most first offenders are not looking at lengthy jail time -- but there is more going on than the criminal charge alone. A DWI triggers two separate processes at once: the criminal case and a civil license action under the implied consent law. They run on different tracks and different deadlines, and the license side often moves faster than people expect.
The single most common mistake after a first DWI is treating it as one problem when it is really two, and missing a deadline on the side nobody warned you about.
The Two Tracks
- The criminal case. A first DWI with no aggravating factors is generally charged as a misdemeanor. Penalties can include fines, probation, and possible jail, though many first offenders receive probationary outcomes. The presence of "aggravating factors" -- such as a very high alcohol concentration, a child in the vehicle, or a test refusal -- can raise the degree.

- The license (implied consent) case. Separately, your license can be revoked administratively, and there is a limited window to challenge that revocation. Missing that window can forfeit the challenge regardless of what happens in the criminal case. [VERIFY: confirm the current deadline and procedure to challenge implied consent revocation (Minn. Stat. 169A.53) before publishing.]
Other Consequences to Expect
- Possible license plate impoundment or ignition interlock requirements in certain situations. [VERIFY: confirm current interlock/plate-impoundment triggers for a first offense.]
- Insurance impacts and a record that can enhance any future DWI within the look-back period.
- A chemical-use assessment and related conditions in many cases.
Where a Defense Focuses
First DWIs are frequently more defensible than people assume. Common focal points include whether the traffic stop was lawful, whether the arrest was supported by probable cause, how field sobriety and chemical testing were conducted, and whether the implied consent advisory and procedures were followed. Any of these can affect both tracks. [VERIFY: confirm current suppression and testing-challenge standards before relying on specifics.]
What this means for you: act on both tracks, and act early -- the license deadline in particular does not wait for the criminal case. Even a first offense is worth a close, prompt look rather than an assumption that pleading is the only option.
Key Terms
- Implied consent: The civil license process that runs parallel to the criminal DWI case.
- Aggravating factor: A circumstance (high test result, child passenger, refusal) that can raise the offense degree.
- Ignition interlock: A device that may be required to keep driving in certain cases.
- Look-back period: The window during which a prior DWI enhances a new one.

Frequently Asked Questions
Will I go to jail for a first DWI?
A first DWI is usually a misdemeanor, and many first offenders receive probationary outcomes rather than significant jail, though it depends on the facts and any aggravating factors. This is general information, not a prediction about any specific case.
Why is there a separate license case?
Minnesota's implied consent law creates a civil license process that runs alongside the criminal case. It has its own deadlines, and the license side often moves faster.
How long do I have to challenge the license revocation?
There is a limited window, and missing it can forfeit the challenge. Because the exact deadline is time-sensitive, confirm it and act quickly.
Can a first DWI be challenged or reduced?
Often yes. The lawfulness of the stop and arrest and how testing was conducted are common focal points that can affect the outcome on both tracks.
Will a first DWI affect a future one?
Yes. A prior DWI can enhance a later offense within the look-back period, which is one reason a first case matters more than it may seem.
