The Difference between “Driving While Impaired” and “Driving Under the Influence”
The terms DWI and DUI often are used interchangeably, but in Maryland, they actually are two different offenses:
- DWI, or driving while impaired—In Maryland, driving while impaired is considered a less serious offense than driving under the influence. You can be charged with DWI if your blood alcohol concentration (BAC) is between .07 and .08. Often, a person charged with DWI will pass the BAC test but exhibit physical indications of impairment, such as slurred speech or erratic driving.
The penalties for DWI include up to 60 days of incarceration and a $500 fine for the first offense. Subsequent convictions can lead to up to a year in jail and additional fines. A DWI conviction also results in an 8-point penalty on your driving record, which will cause your license to be suspended. - DUI, or driving under the influence—You can be charged with a DUI only if your BAC exceeds .08. A first-time conviction for DUI can result in a year in jail and a $1,000 fine. Your second and third convictions can each lead to another 12 months of incarceration and an additional $1,000 fine. DUI adds 12 points to your driving record, leading to revocation of your license for a period of time.

Because the term “assault and battery” is heard so commonly, there can be a perception that it’s a single crime. In fact, assault and battery are separate offenses, and you can potentially be charged with both for a single incident.
In Maryland, when a police officer pulls you over, regardless of the reason, the officer may ask if you have been
When police pull you over and suspect you’re driving under the influence or while impaired, it’s common for them to administer a breath test and use the results in a criminal prosecution. However, a 2019 study by the New York Times found that those tests, long considered an essential tool in

Furthermore, certain professionals and third parties, such as social workers and medical personnel, are required by law to report actual knowledge or even reasonable suspicion of child abuse.
In the state of Maryland, unlike many states, there’s a legal distinction between DUI,or driving under the influence, and DWI—driving while intoxicated. Conviction on charges of driving under the influence of alcohol requires evidence of a blood alcohol content (BAC) of .08% or higher. To be charged and convicted of the lesser offense of driving while intoxicated, there’s no requirement of a specific BAC—prosecutors must show only that you were impaired by alcohol and that it affected your ability to drive. It’s also important to understand that you need not be operating a motor vehicle on the road to be charged with DWI; you need only be in “actual physical control” of the vehicle while the car’s engine is running.
In Maryland, as in all states, the possession of certain controlled substances is a violation of the law. That includes not only “street drugs,” such as marijuana, meth, cocaine, and heroin, but also prescription medication. Maryland has decriminalized possession of small amounts of marijuana, treating the offense like a moving violation. Accordingly, marijuana is no longer classified as a controlled dangerous substance under Maryland law.
Under Maryland law, certain criminal acts can be prosecuted as domestic violence when committed against a household or family member. Those crimes which can qualify as domestic violence include:
