First-Degree vs. Fourth-Degree DWI in Minnesota: What’s the Difference?

Minnesota’s DWI laws operate on a tiered system, with penalties increasing based on prior offenses, aggravating factors, and the severity of the incident. The contrast between a Fourth-Degree DWI and a First-Degree DWI demonstrates just how wide the range of consequences can be. While a Fourth-Degree DWI applies to first-time, low-level offenses, a First-Degree DWI is a felony that can lead to lengthy prison sentences and long-term restrictions. Many individuals start by reviewing Minnesota’s classification for First Degree DWI in Minnesota to understand how serious the charge can be.

Understanding these distinctions is essential for protecting your future and knowing what to expect if you or someone you know faces a DWI charge. Below is a clear breakdown of what separates these two degrees, what penalties apply, and why these differences matter.

Minnesota’s DWI Degree System: An Overview

Minnesota categorizes DWI charges into four degrees, with First-Degree being the most severe. The level of the charge depends on multiple factors, including blood alcohol concentration (BAC), prior offenses, chemical test refusals, and other aggravating circumstances. The purpose of this tiered system is to impose greater penalties on repeat offenders or those who present elevated risks to the public.

A Fourth-Degree DWI represents the least severe category, while a First-Degree DWI reflects multiple prior offenses or past felony convictions. Because the consequences differ so drastically, knowing the distinctions can help you understand legal exposure and potential outcomes.

What Is a Fourth-Degree DWI?

A Fourth-Degree DWI is Minnesota’s lowest-level impaired-driving charge. It typically applies when the following conditions are met:

  • It is the driver’s first DWI offense

  • BAC is below 0.16

  • No aggravating factors apply

  • There is no chemical test refusal

Because it’s the least serious charge, many people research guidelines for Fourth-Degree misdemeanor DWI to gain clarity about the process and expected penalties.

Penalties for Fourth-Degree DWI

Even though it is the least severe charge, a Fourth-Degree DWI still carries meaningful consequences:

  • Up to 90 days in jail

  • Fines of up to $1,000

  • Possible probation

  • Temporary license suspension

  • Mandatory chemical dependency evaluation

For many first-time offenders, jail time may be replaced with probation or treatment requirements. Still, the incident becomes part of your driving record and can affect insurance rates for years.

What Is a First-Degree DWI?

A First-Degree DWI is Minnesota’s most serious impaired driving charge, classified as a felony. This level applies when a driver has:

  • Three or more prior DWI offenses within 10 years

  • A prior felony DWI

  • A past felony conviction for criminal vehicular operation involving alcohol

Unlike lower-degree DWIs, First-Degree charges are not based solely on BAC. They reflect patterns of repeated impaired driving or serious past offenses.

Penalties for First-Degree DWI

The consequences of a First-Degree DWI are severe and long-lasting:

  • Up to seven years in prison

  • Fines up to $14,000

  • Mandatory minimum prison or jail sentences for repeat offenders

  • Felony record

  • Vehicle forfeiture

  • Long-term license cancellation with strict reinstatement rules

A felony DWI impacts employment prospects, voting rights, firearm ownership, and future driving privileges. The consequences extend far beyond the courtroom.

Key Differences Between First-Degree and Fourth-Degree DWI

  1. Severity of Charge
    Fourth-Degree DWIs are misdemeanors; First-Degree DWIs are felonies. This difference alone creates drastically different life outcomes.
  2. Aggravating Factors
    A Fourth-Degree DWI involves no aggravating factors. The presence of any one—such as a high BAC, child in the vehicle, or prior offenses—can raise the charge to a higher degree.
  3. Jail or Prison Exposure
    Fourth-Degree DWI: Up to 90 days in jail, often suspended.
    First-Degree DWI: Up to seven years in prison, with mandatory minimums.
  4. License Penalties
    Fourth-Degree DWI results in a temporary revocation.
    First-Degree DWI often leads to complete cancellation and substantial barriers to reinstatement.
  5. Vehicle Consequences
    Vehicle forfeiture is common in First-Degree cases but rare for Fourth-Degree offenses.
  6. Long-Term Impact
    First-Degree DWIs carry lifelong consequences, including a felony record. Fourth-Degree DWIs, while serious, generally offer more opportunities for rehabilitation.

How Charges Escalate

Charges escalate quickly based on:

  • A BAC of 0.16 or higher

  • Prior DWIs

  • Refusal to take a chemical test

  • Presence of a child passenger

A single aggravating factor can elevate a Fourth-Degree charge to Third-Degree. Two factors or a high BAC with a prior offense may raise it even further. Three prior offenses trigger the First-Degree charge automatically.

Which Charge Is More Common?

Fourth-Degree DWIs are most common because they apply to first-time offenders. First-Degree DWIs represent a much smaller group of cases but carry severe outcomes. Minnesota’s system is designed to offer leniency to first-time offenders while imposing harsher consequences for repeat or dangerous conduct.

Steps to Take After a DWI Arrest

Regardless of the degree, it is important to take immediate action:

  • Review the charges and their implications

  • Request a hearing to challenge your license revocation

  • Follow court and administrative deadlines

  • Begin addressing treatment or evaluation requirements

  • Seek legal guidance early

The sooner you act, the more options you typically have.

First-time DWI defendants often benefit from learning about the options available to new arrestees that may reduce the long-term impact of the charge, frequently turning to the American Bar Association  for reliable guidance.

Conclusion

Understanding the difference between First-Degree and Fourth-Degree DWI is essential for anyone navigating Minnesota’s impaired driving laws. Fourth-Degree DWIs are serious but generally manageable, with limited long-term effects when addressed promptly. First-Degree DWIs, on the other hand, involve felony penalties that can reshape a person’s future for years to come.

Knowledge of the distinctions helps individuals make informed decisions, protect their rights, and take the right steps during what is often a stressful and confusing process. If you need help, more information, or additional articles written in this style, feel free to ask.
