A DUI or DWI charge in Maryland can affect both the criminal case against you and your ability to drive. Metzner & Houpt represents clients facing DUI and DWI charges in Hagerstown and throughout Washington County, Maryland.

The court case is only part of the process. Depending on the circumstances, an arrest can also lead to separate action by the Maryland Motor Vehicle Administration (MVA), including suspension of driving privileges or participation in the Ignition Interlock System Program. Some MVA deadlines arise shortly after an arrest, so it is important to review your citations, testing paperwork, and any Order of Suspension promptly.

DUI and DWI Are Different Offenses in Maryland

Maryland law distinguishes between driving under the influence of alcohol (DUI) and driving while impaired by alcohol (DWI). Both are prohibited by Maryland Transportation Article § 21-902, but DUI is the more serious of the two offenses and carries greater potential criminal penalties.

A blood or breath alcohol concentration of 0.08 or higher is considered being "under the influence of alcohol per se" under Maryland law. However, a result below 0.08 does not necessarily rule out an alcohol-related driving charge.

Maryland's evidentiary rules provide that:

  • An alcohol concentration of 0.08 or higher constitutes being under the influence of alcohol per se.
  • An alcohol concentration of at least 0.07 but less than 0.08 is prima facie evidence of driving while impaired by alcohol.
  • A result above 0.05 but below 0.07 creates no presumption either for or against impairment, although it may be considered together with other competent evidence.
  • A result of 0.05 or less creates a presumption that the person was not under the influence of alcohol and was not driving while impaired by alcohol.

For that reason, DUI and DWI should not be described simply as two different "legal limits." The circumstances of the traffic stop, the officer's observations, test results, and other evidence can all matter.

What Happens After a DUI or DWI Arrest?

An impaired-driving case can involve two separate processes: the criminal charge handled through the courts and driver's-license issues handled through the MVA.

During an impaired-driving investigation, an officer may ask a driver to perform field sobriety tests and may request an alcohol test. If a Maryland-licensed driver refuses the requested chemical test or takes a test showing an alcohol concentration of 0.08 or more, the officer may confiscate the Maryland driver's license, serve an Order of Suspension, and issue a temporary license.

The criminal case and the MVA process are related, but they are not the same proceeding. As a result, driver's-license deadlines may arise before the criminal case reaches court.

The Maryland MVA provides current information about driving under the influence.

MVA Hearing Deadlines Can Come Quickly

For an Order of Suspension arising from a chemical-test refusal or an alcohol concentration of 0.08 or more, Maryland law generally permits a driver to request an administrative hearing within 30 days after the Order of Suspension is issued.

Timing within that period matters. If the hearing is requested at the time of the suspension order or within 10 days, the timing can affect the driver's temporary driving authorization while the hearing process is pending.

A hearing may still be requested after the first 10 days and within 30 days, but a request made after 10 days does not extend the 45-day temporary license issued by the officer.

Because the available options depend on the circumstances and the paperwork issued in the individual case, drivers should read their Order of Suspension carefully rather than assuming that the court date is the only deadline that matters.

Ignition Interlock and Driving Privileges

Maryland's Ignition Interlock System Program permits or requires participating drivers to operate only vehicles equipped with an approved ignition interlock device.

Under current Maryland law, participation in the program is required following a conviction or probation before judgment for driving under the influence of alcohol or driving while impaired by alcohol. Ignition interlock may also be available as an alternative to certain administrative license suspensions when the driver is eligible.

The length of participation and the options available can depend on the circumstances of the case, test results or refusal, the driver's record, and the basis for participation. The MVA administers the program and issues restricted licenses to eligible participants.

How a DUI or DWI Case Can Be Evaluated

Every impaired-driving case depends on its own facts. Relevant evidence may include the circumstances of the traffic stop, the officer's observations, field sobriety testing, breath or blood testing, police video, paperwork generated during the arrest and testing process, and the driver's prior record.

An attorney can review the available evidence, explain the criminal and MVA processes, identify issues that may affect the case, and advise the client about the options available under Maryland law.

Frequently Asked Questions

Maryland law treats DUI and DWI as distinct alcohol-related driving offenses. DUI means driving under the influence of alcohol, including being under the influence per se based on an alcohol concentration of 0.08 or higher. DWI means driving while impaired by alcohol. DUI is the more serious offense and carries greater potential criminal penalties.

Yes. In Maryland, an alcohol concentration of at least 0.07 but less than 0.08 is prima facie evidence of driving while impaired by alcohol. A result above 0.05 but below 0.07 creates no presumption either for or against impairment, but it may be considered along with other evidence. An alcohol-test result is therefore not the only evidence that can matter in an impaired-driving case.

That depends on the circumstances. If a Maryland driver refuses a requested chemical test or has a test result of 0.08 or higher, the MVA administrative process can begin. The officer may confiscate the Maryland driver's license, serve an Order of Suspension, and issue a temporary license. The criminal court case and MVA driver's-license process are separate matters.

Maryland law generally permits a written hearing request within 30 days after the Order of Suspension is issued. Requesting the hearing at the time of the order or within the first 10 days is important because a request made after 10 days does not extend the 45-day temporary license issued by the officer.

It can be required in several circumstances. Under current Maryland law, participation in the Ignition Interlock System Program is required following a conviction or probation before judgment for DUI or DWI. Ignition interlock may also be available or required in connection with certain MVA license actions. The applicable requirements depend on the circumstances of the case.
