Introduction
Being arrested for a DUI (Driving Under the Influence) or DWI (Driving While Impaired) in Maryland can be a daunting experience. Whether this is your first offense or you’ve faced charges before, the consequences of a DUI or DWI conviction can have a long-lasting impact on your life. From heavy fines and license suspension to the potential for jail time, it’s crucial to understand your rights and the legal process.
However, just because you’ve been arrested for DUI or DWI in Maryland doesn’t mean you’re automatically guilty. There are a number of defense strategies available that can help reduce or even dismiss the charges. In this article, we’ll explore what DUI and DWI are, the differences between them, the legal penalties, and the most effective defense strategies that a Maryland DUI lawyer can use to help you fight your charges.
What is DUI and DWI in Maryland?
In Maryland, the terms DUI and DWI are often used interchangeably, but they refer to different levels of impairment. Understanding the distinction between the two is important for your defense.
DUI (Driving Under the Influence)
A DUI charge is typically given when a driver is caught with a blood alcohol concentration (BAC) of 0.08% or higher. This level of intoxication is considered legally impaired and can significantly affect your ability to drive safely.
If you’re arrested for DUI in Maryland, it means the officer believes you were driving while under the influence of alcohol or drugs and that your BAC is above the legal limit. DUI offenses are considered more severe than DWI offenses and carry more severe penalties.
DWI (Driving While Impaired)
A DWI charge is generally given when your BAC is between 0.04% and 0.08%, which means you’re impaired but not to the level of being legally intoxicated. While it’s a lesser charge than DUI, it still carries serious consequences and can result in fines, license suspension, and other penalties.
You can be arrested for DWI even if your BAC is below the legal limit if the officer observes signs of impairment, such as swerving, slow reactions, or erratic driving.

Penalties for DUI and DWI in Maryland
If convicted of DUI or DWI in Maryland, the penalties can vary depending on whether it’s your first offense or if you have prior convictions. The state takes impaired driving seriously, and the consequences can have significant effects on your life.
Penalties for DUI
- First Offense: A first-time DUI conviction can result in up to 1 year in prison and/or fines up to $1,000. Additionally, your driver’s license may be suspended for 6 months. You may also be required to complete an alcohol education program or treatment.
- Second Offense: If you’ve been convicted of a DUI before, a second offense can lead to up to 2 years in prison and fines of up to $2,000. Your license may be suspended for 1 year or longer.
- Third or Subsequent Offenses: A third or subsequent DUI offense can lead to a mandatory prison sentence of up to 5 years, in addition to fines and a lengthy license suspension.
Penalties for DWI
- First Offense: A first-time DWI conviction may result in up to 60 days in jail and/or a fine of up to $500. Your license could be suspended for 2 months.
- Second Offense: A second DWI conviction could lead to up to 1 year in jail and/or fines of up to $500, along with a 1-year license suspension.
- Third or Subsequent Offenses: Multiple DWI convictions may lead to increased jail time, fines, and longer license suspensions, depending on the circumstances.
In addition to these legal penalties, both DUI and DWI convictions can result in higher car insurance premiums and difficulty obtaining certain jobs, particularly those that involve driving.
Common DUI and DWI Defenses in Maryland
If you’ve been charged with DUI or DWI in Maryland, it’s important to know that there are several defenses your attorney might use to challenge the charges. The success of these defenses depends on the details of your case, the evidence presented, and the expertise of your Maryland DUI lawyer.
1. Invalid or Inaccurate Breathalyzer Test Results
One of the most common defenses in DUI and DWI cases is challenging the accuracy of the breathalyzer test. Breathalyzer devices are not always reliable, and their readings can be affected by several factors, including:
- Improper Calibration: If the breathalyzer device wasn’t properly calibrated, the results could be inaccurate.
- Improper Use: If the officer did not properly administer the test or didn’t follow the required procedures, the results could be challenged.
- Medical Conditions: Certain medical conditions, such as acid reflux or diabetes, can affect breathalyzer readings. If you have a condition that could interfere with the accuracy of the test, it could be used in your defense.
If your DUI lawyer can show that the breathalyzer test was faulty or improperly administered, it may lead to the dismissal of the charges or a reduced sentence.
2. Illegal Traffic Stop
For the police to pull you over and conduct a DUI or DWI investigation, they must have a valid reason for the traffic stop. If the police did not have probable cause or reasonable suspicion to stop you, any evidence they gathered afterward may be deemed inadmissible in court.
For example, if the officer stopped you without a legitimate reason—such as swerving in your lane or running a red light—your lawyer may argue that the stop was illegal, and therefore, the evidence obtained (such as field sobriety tests or breathalyzer results) should be excluded.
3. Field Sobriety Test Failures
Field sobriety tests, which include tasks like walking in a straight line or standing on one leg, are subjective and can be influenced by a variety of factors unrelated to alcohol or drug impairment. If you were not given proper instructions or were affected by conditions such as fatigue, anxiety, or even weather, your DUI lawyer may argue that the results of these tests are unreliable.
Moreover, field sobriety tests have a high failure rate among sober individuals, especially when the officer does not administer the test properly.
4. Lack of Evidence
Another potential defense is to argue that the prosecution doesn’t have enough evidence to prove beyond a reasonable doubt that you were impaired while driving. For instance, if the officer did not observe any signs of impairment (such as erratic driving or slurred speech), or if the breathalyzer or blood test results are inconclusive or inaccurate, it may be possible to argue that the evidence is insufficient to support a conviction.
5. Prescription Medication or Medical Conditions
Sometimes, individuals may appear impaired due to prescription medications or underlying medical conditions, even if they were not under the influence of alcohol or illegal substances. If you were taking a legal medication that caused drowsiness or affected your coordination, this could be used as a defense to show that you weren’t impaired by alcohol or drugs.
How a Maryland DUI Lawyer Can Help
A Maryland DUI lawyer plays a critical role in protecting your rights and defending you against DUI or DWI charges. They can:
- Evaluate the Evidence: Your lawyer will thoroughly review the evidence, including breathalyzer results, witness statements, and the circumstances of your arrest, to identify any weaknesses in the prosecution’s case.
- Challenge the Evidence: Based on the review, your lawyer may challenge the legality of the traffic stop, the accuracy of the breathalyzer test, or the way field sobriety tests were conducted.
- Negotiate a Plea: In some cases, your lawyer can negotiate with the prosecution to reduce your charges or secure a more lenient sentence, such as probation or alcohol education programs.
- Represent You in Court: If your case goes to trial, your Maryland DUI lawyer will represent you in court, making arguments on your behalf and cross-examining the prosecution’s witnesses.
It’s important to seek legal representation as soon as possible after a DUI or DWI arrest. Early intervention can help protect your rights and increase the likelihood of a favorable outcome.
