DUI vs. DWI in Maryland: What Is the Difference?

Maryland law draws a clear legal distinction between DUI and DWI, and that distinction matters enormously for the penalties you face.

DUI (Driving Under the Influence) is the more serious charge. It applies when your blood alcohol concentration (BAC) is 0.08% or higher, or when evidence shows you were substantially impaired by alcohol or drugs. Under Md. Code, Transportation § 21-902, a DUI conviction carries significantly harsher penalties than a DWI.

DWI (Driving While Impaired) is the lesser charge. It applies when your BAC is between 0.07% and 0.08%, or when an officer observes signs of impairment even without reaching the DUI threshold. DWI charges often rely heavily on field sobriety test performance and officer testimony.

Important: Maryland’s implied consent law (Md. Code, Transportation § 16-205.1) means that by driving on Maryland roads, you have legally consented to breath or blood testing. Refusing a test triggers its own separate MVA penalties, and refusal can still be used as evidence against you in court.

What’s at Stake If You Are Convicted of a DUI or DWI in Maryland

Maryland law treats DUI and DWI charges as distinct offenses with different consequences. Both are misdemeanors, but both carry the potential for jail time, substantial fines, license suspension, points on your driving record, mandatory ignition interlock, and a permanent mark on your criminal record that can affect employment, housing, and professional licensing for years to come.

The specific consequences you face depend on a number of factors, including:

  • Whether you are charged with DUI or DWI. DUI is the more serious charge and carries heavier penalties
  • Your blood alcohol concentration (BAC) at the time of the stop
  • Whether this is a first offense or you have prior convictions within the past five years
  • Whether a minor was in the vehicle at the time of the alleged offense
  • Whether anyone was injured as a result of the alleged impaired driving
  • Whether you refused a breathalyzer or blood test, refusal carries its own additional penalties
  • How the Maryland Motor Vehicle Administration (MVA) handles the administrative license case alongside the criminal case

Criminal Penalties

Under Md. Code, Transportation § 21-902, both DUI and DWI convictions can result in imprisonment, substantial fines, and a permanent criminal record. Penalties increase significantly for repeat offenses within five years of a prior conviction, for offenses involving minor passengers, and for third or subsequent offenses. Maryland also imposes mandatory minimum jail sentences for certain repeat DUI offenses — minimums that cannot be suspended or reduced to probation.

License Suspension and Points

A DUI conviction adds 12 points to your Maryland driving record — enough to make you eligible for license revocation. A DWI conviction adds 8 points, making you eligible for suspension. The MVA handles this administrative process separately from the criminal case, and the 10-day window to request an MVA hearing after your arrest is critical.

Ignition Interlock Requirements

Under Maryland’s Noah’s Law, ignition interlock device (IID) requirements apply to virtually all DUI and DWI convictions — including first-time offenders who receive a Probation Before Judgment. Depending on your BAC and the specifics of your case, the interlock period can range from several months to several years.

Collateral Consequences

Beyond the statutory penalties, a DUI or DWI conviction can affect your life in ways that are often not obvious at the time of arrest:

  • Significant increases in auto insurance premiums — often for years
  • Employment consequences, especially for commercial drivers, healthcare workers, and licensed professionals
  • Immigration consequences for non-citizens
  • Difficulty renting housing or securing certain types of credit
  • Restrictions on travel to certain countries, including Canada
  • For a second offense, required to complete an alcohol abuse assessment and treatment program
Because every case is different, the best way to understand what you are actually facing is to speak with a defense attorney who can review the specific charges and circumstances. Contact Walsh-Little Law for a free consultation.

The MVA Hearing: Why the 10-Day Deadline Is Critical

When you are charged with a DUI or DWI in Maryland, two separate legal processes begin simultaneously: your criminal case in court, and an administrative license suspension through the Maryland Motor Vehicle Administration (MVA). Many people focus only on the criminal charge and lose their license before ever stepping into a courtroom.

Here is what happens immediately after a DUI arrest in Maryland:

  • Your license is confiscated, and you are issued a temporary paper license valid for 45 days
  • You have 10 days from the date of the traffic stop to request an MVA hearing if you want to prevent your license from being suspended before your hearing
  • If you miss the 10-day window, your driving privileges are automatically suspended on day 46
  • If you miss the 30-day window entirely, you permanently waive your right to contest the MVA suspension
Do not wait. If you have been charged with a DUI in Baltimore, contact Walsh-Little Law immediately. Missing the 10-day MVA deadline is one of the most common and costly mistakes DUI defendants make, and it cannot be undone.

DUI Defense Strategies in Baltimore

Every DUI case is different, and the right defense depends on the specific facts of your arrest. As an experienced Baltimore DUI defense attorney, David Walsh-Little examines every angle of the prosecution's case, including:

Challenging the Legality of the Traffic Stop

Police must have reasonable suspicion to pull you over. If the stop was unlawful, no traffic violation, no reasonable basis, any evidence gathered after that stop may be suppressed. This can effectively end the prosecution's case.

Questioning Field Sobriety Test Reliability

Field sobriety tests (FSTs) are notoriously unreliable. Environmental conditions such as uneven pavement, poor lighting, or inclement weather can affect performance. So can medical conditions, fatigue, footwear, and anxiety. David scrutinizes how these tests were conducted and whether they were properly administered.

Challenging Breathalyzer and Blood Test Accuracy

Breathalyzer equipment must be properly calibrated and maintained. Officers must follow strict protocols when administering breath and blood tests. Errors in calibration records, improper testing procedures, or mishandled blood samples can render BAC results inadmissible.

Disputing the MVA's Grounds for Suspension

At an MVA hearing, the administrative law judge can only consider a narrow set of facts: whether the officer had reasonable grounds to believe you were impaired, and whether proper procedures were followed. A well-prepared challenge at the MVA hearing can preserve your license while your criminal case proceeds.

Negotiating a Reduction to DWI or Pursuing PBJ

In appropriate cases, David works to negotiate a reduction from DUI to DWI, or to secure a Probation Before Judgment (PBJ), a disposition that keeps a conviction off your permanent record. These outcomes depend on the evidence, your prior record, and the skill of your attorney in negotiating with the prosecution.

Ignition Interlock Requirements: Noah's Law

Maryland's Noah's Law, updated in October 2024, now requires an ignition interlock device (IID) for virtually all DUI and DWI convictions, including first-time offenders who receive a Probation Before Judgment (PBJ). Previously, PBJ recipients could avoid the interlock requirement entirely. That loophole is now closed.

An IID is a camera-enabled breathalyzer connected to your vehicle's ignition. Your car will not start if alcohol is detected above 0.025% BAC. Depending on your offense and BAC level, mandatory enrollment in the Ignition Interlock System Program (IISP) ranges from 180 days to several years.
