DUI vs. DWI in Maryland: What's the Difference and What Are the Penalties?
If you have been arrested for impaired driving in Maryland, you may have heard the terms DUI and DWI used interchangeably. However, Maryland law distinguishes between driving under the influence (DUI) and driving while impaired (DWI), and understanding these differences is important when facing criminal charges.
Both offenses can carry serious consequences, including fines, possible incarceration, points on your driving record, and restrictions on your driving privileges. Whether you were stopped in Rockville, Bethesda, Silver Spring, or elsewhere in Montgomery County, understanding the allegations is an important first step toward protecting your rights.
Understanding DUI vs. DWI in Maryland
Under Maryland law, DUI generally involves driving while under the influence of alcohol, while DWI involves driving while impaired by alcohol. Maryland also has separate provisions addressing impairment by drugs and controlled dangerous substances.
A blood alcohol concentration (BAC) of 0.08 or higher can establish that a driver was under the influence of alcohol per se. A BAC of 0.07 may create a presumption of impairment. However, prosecutors may also rely on officer observations, driving behavior, field sobriety tests, and other evidence.
The distinction matters because DUI and DWI offenses can carry different criminal penalties and administrative consequences.
What Are the Penalties for DUI and DWI in Maryland?
For a first offense, Maryland law generally provides the following maximum criminal penalties for standard alcohol-related charges:
DUI: Up to one year in jail and a $1,000 fine.
DWI: Up to two months in jail and a $500 fine.
Enhanced penalties may apply depending on prior convictions, whether a minor was transported, and other circumstances.
A conviction may also result in points assessed by the Maryland Motor Vehicle Administration (MVA), along with potential license suspension or revocation. Separate administrative consequences may arise from chemical testing results or a refusal to submit to testing.
Because criminal proceedings and MVA actions are separate, addressing one does not necessarily resolve the other.
How Can a DUI Defense Attorney Challenge the Evidence?
An arrest does not automatically mean that the prosecution can establish guilt beyond a reasonable doubt.
A defense attorney may review several important aspects of the investigation, including:
Whether law enforcement had a lawful basis for the traffic stop.
Whether field sobriety tests were administered and interpreted appropriately.
Whether breath or blood testing complied with applicable requirements.
Whether officer observations are consistent with other available evidence.
Whether constitutional or procedural issues affect the admissibility of evidence.
