When Does a DUI Escalate to a Felony in Maryland?

In Maryland, most DUI charges are classified as misdemeanors. However, under certain severe circumstances, a DUI can escalate to a felony offense—bringing with it far more serious consequences, including years in prison, a permanent criminal record, and a lifetime of collateral damage.

A DUI charge can rise to the level of a felony when any of the following factors apply:

  • The DUI results in a fatal crash – Causing the death of another person while driving under the influence is the most common reason a DUI is charged as a felony. This typically results in charges such as vehicular manslaughter, which carries a prison sentence of up to 10 years in Maryland.
  • The DUI causes life-threatening injuries – If your alleged impairment led to a crash that caused another person to suffer serious bodily harm, you could face felony-level charges for causing serious injury while impaired.
  • Multiple prior DUI convictions – Although Maryland does not automatically classify repeat DUI offenses as felonies, a judge may impose harsher sentencing if you have prior convictions. Prosecutors may also pursue more aggressive charges, particularly if the prior offenses are recent or involved aggravating circumstances.
  • DUI with a child in the vehicle – Driving under the influence while transporting a minor (under 18) can significantly increase penalties. While often still a misdemeanor, prosecutors may charge it more aggressively, especially if harm results or multiple charges are present.
  • Driving with a suspended license due to prior DUI – If you were already prohibited from driving due to a past DUI and were caught under the influence again, your situation may be elevated to felony status, depending on the context and cumulative offenses.
  • Third-party property damage or reckless endangerment – While not a standalone cause for felony charges, causing major property damage, fleeing the scene, or engaging in reckless behavior (like driving at high speeds or through pedestrian zones) may be used to support a felony prosecution.

Felony DUI charges in Maryland are extremely serious and often involve additional charges layered on top of the DUI itself—such as manslaughter, assault with a vehicle, child endangerment, or leaving the scene of an accident. The penalties can be life-altering, and even a first-time offender can face felony prosecution if the outcome of the incident is severe.

Crushing Penalties for Committing a DUI Felony Offense

A felony DUI conviction in Maryland carries severe penalties that can impact every aspect of your life. The severity depends on your level of impairment at the time of the incident.

If your BAC is 0.08 or higher, or if you have drugs in your system, or both:

  • Maximum prison sentence of 5 years
  • Fines up to $5,000

If your BAC was 0.07 or higher but below 0.08, or if you had drugs in your system, or both:

  • Maximum prison sentence of 3 years
  • Fines up to $3,000

Beyond immediate penalties, a felony DUI conviction means:

  • Permanent criminal record
  • Difficulty finding employment
  • Limited housing opportunities
  • Suspended or revoked driving privileges

How Our Maryland Felony DUI Lawyers Can Help You Fight Felony Charges

At Maronick Law LLC, we dedicate ourselves to achieving the best possible outcome for you. Here's how we build your DUI / DWI defense strategy:

Challenging Breath Test Evidence

Breathalyzer results aren't infallible. Breathalyzer devices require precise maintenance and operation to produce accurate readings.

Our felony DWI attorneys in MD scrutinize machine maintenance records, calibration history, and lab accreditation status.

Overlooked maintenance checks or improper procedures can invalidate the entire test result.

Exposing Blood Test Flaws

Blood tests also undergo similar scrutiny. Even minor procedural errors can compromise results. We examine:

  • Chain of custody documentation
  • Blood draw timing and procedures
  • Sample storage conditions
  • Testing protocols
  • Test tube preservation standards

A single broken link in the chain of custody can lead to evidence suppression.

Breaking the Causation Chain

Prosecutors must prove beyond reasonable doubt that your impairment directly caused the death. That's where our experience becomes invaluable. We investigate every possible contributing factor:

  • Road conditions and design flaws
  • Actions of other drivers involved
  • Victim's medical history

Sometimes tragedy strikes due to mechanical failures beyond anyone's control. We investigate:

  • Complete vehicle maintenance history
  • Brake system integrity

Often, factors beyond the driver's control contribute to tragic outcomes.

Plea Negotiating

When evidence presents challenges, we leverage our deep understanding of criminal justice system to secure favorable outcomes:

  • Reduced charges
  • Alternative sentencing options
  • Treatment programs
  • Probation alternatives

Every case deserves a strong defense. Contact us to discuss your defense options with our Maryland felony DUI lawyers and protect your future.

Our track record, in our clients' own words:

  • ★★★★★

    I recently had Mr. Maronick represent me for my first DUI case. I was very nervous about it because of the results of the DUI incident. The outcome that I was initially looking at was jail time, high fines and a license suspension. He got me out of jail time, I got probation, and the fines were thrown out. All I ended up having to pay were court costs. He really did his job, and I am very appreciative of that. I highly recommend him to be hired for your DUI case or any others you may have.

    Late last year I found myself in a position that I clearly had no ability to get out of on my end. Yes, you guessed it right I caught a DUI. Feeling ashamed and embarrassed I immediately put those feelings to the side and contacted the Maronick Law Firm. From the initial consultation, Tom made me feel at ease about my situation and instructed me on everything to do before my court date I ended up getting the DUI charge dropped to a PB - no points on my license or charges on my record, just a fine and 2yrs probation. To anyone going through a similar scenario, I highly recommend you reach out to the Maronick Law Firm.
