After a DWI arrest, the questions are personal: Will I be able to drive to work? Could I go to jail? What does an old case mean for this one? Whether this is your first arrest or you have been through the process before, understanding the differences can help you make informed decisions.

People often search for “DUI,” but Missouri generally calls the offense driving while intoxicated, or DWI. The number of prior offenses matters, but so do their dates, the underlying records, and the facts of the new allegation. A charge is not a conviction, and a penalty chart cannot tell you how your case will end.

First DWI in Missouri: Take It Seriously From the Start

An ordinary first DWI is a Class B misdemeanor. The maximum punishment is six months in jail and a $1,000 fine. Circumstances such as a passenger younger than 17 or an injury can increase the charge, even without a prior DWI.

Some first offenders may qualify for a suspended imposition of sentence (SIS), subject to statutory conditions, including at least two years of probation. A high blood alcohol concentration can restrict that option. Do not assume probation is automatic or that an SIS eliminates every consequence.

For you, the immediate task is to understand both the evidence and the practical impact of any proposed resolution. Ask what probation would require, what costs may arise beyond a fine, and how the outcome could affect your job or professional license. Discuss those concerns before deciding how to respond to the charge.

Second DWI: The Timing of the Prior Offense Matters

Missouri defines a “prior offender” to include someone found guilty of one qualifying intoxication-related traffic offense that occurred within five years of the current offense. A DWI charged and proved on that basis is a Class A misdemeanor, carrying up to one year in jail and a $2,000 fine.

If your earlier offense is older, do not assume it is irrelevant. Criminal enhancement rules and driver-license rules use different standards. Your attorney needs the actual court records and offense dates to evaluate the effect of the earlier case.

Being accused again can bring understandable fear or embarrassment. Those feelings should not keep you from getting advice. Tell your attorney about every earlier case, including cases from another state or a municipal court, and explain any treatment, work obligations, or family responsibilities that need to be considered.

Third DWI: When a Missouri Charge Can Become a Felony

Two qualifying prior intoxication-related traffic offenses committed on separate occasions can support “persistent offender” status. Unlike the ordinary prior-offender definition, this category has no five-year limit. Certain injury- or death-related histories can also change the classification.

A DWI involving persistent-offender status is a Class E felony, with exposure of up to four years in prison and a $10,000 fine. Special sentencing restrictions apply to prior and persistent offenders, including limits on SIS and probation eligibility. These maximums are not predictions of your sentence.

A felony allegation calls for careful review of both the current evidence and the records offered to establish prior offenses. Bring whatever older paperwork you have, even if it seems incomplete. Your attorney can identify what additional records are needed and explain which sentencing options may legally be available.

Your Driver's License Is a Separate, Urgent Issue

The criminal charge and your driving privileges can proceed on separate tracks. A favorable result in court does not automatically resolve an administrative license action. According to the Missouri Department of Revenue, conviction-related consequences generally include:

• First conviction: a 90-day suspension, with restricted driving potentially available.
• Second conviction: normally a one-year revocation; two qualifying convictions within five years can also produce a five-year denial.
• Three or more qualifying convictions: a ten-year denial.

Restricted or limited driving privileges depend on eligibility and conditions; they are not automatic. Reinstatement may involve SATOP, insurance filings, fees, and an ignition interlock device.

Deadlines can arrive before your court date. A request for an administrative hearing on a BAC-based suspension or revocation generally must be made within 15 days after the notice is issued. A chemical-test refusal can trigger a separate one-year revocation; a petition for review generally must be filed within 30 days after that notice is issued. Have the specific notice reviewed promptly, and confirm whether you may legally drive.

What Should You Do After a Missouri DWI Arrest?

Start by organizing your paperwork: the ticket, charging documents, bond conditions, test information, license notices, and prior case records. Write down what you remember about the stop while it is fresh, and preserve relevant messages, receipts, or video. Avoid posting about the incident online.

Make a list of practical concerns for your consultation. Do you drive for a living? Hold a commercial license? Need transportation for children or medical appointments? Have an upcoming court date? These details help your attorney explain the decisions ahead. Follow all court orders and ask before assuming a restriction has ended.
