Maryland law distinguishes between driving under the influence (DUI) and driving while impaired (DWI) based on a person’s blood alcohol content (BAC). DUI is more serious. Any reading above a .06 will lead to an alcohol-related charge.

Charges may be initiated if the police feel that a person is under the influence of prescription medication, a controlled dangerous substance, or both.

The potential penalties of even a first DUI or DWI-related conviction include:

• DUI – up to one year in jail and $1,000 in fines, 12 points on your driver’s license, and a six-month minimum license suspension.
• DWI – up to two months in jail and $500 in fines, eight points on your driver’s license, and a six-month license suspension.
• Underage DUI – Maryland has a zero-tolerance law for minors found driving under the influence, which means a BAC of only .02 percent is enough to be charged with DUI. This could result in a $500 fine and a 45-day driver’s license suspension.
• DUI or DWI with a minor in the vehicle – If transporting a minor at the time of arrest, a person may be sentenced to two years in jail for DUI and up to six months for DWI, and fines may be doubled.

Beyond the criminal and civil penalties associated with a DUI or DWI conviction, the collateral consequences of having a DUI or DWI on your record are severe. In many cases, for years after the incident, a DUI can frustrate your efforts to find employment, promotions, or a professional license. In addition, your insurance company could either cancel your policy or raise your rates substantially.
