In Maryland, what’s the difference between DUI and DWI?

In Maryland, the crime of “drunk driving” is distinguished by the level of impairment. DWI means “driving while impaired.” The maximum penalty is sixty days in jail (and 8 points). DUI means “driving under the influence.” The maximum penalty for a DUI is one year in jail (and 12 points). Obviously, DUI is the more serious offense.

If you receive a DUI in Maryland, the State must prove a higher level of impairment or that you were “substantially” impaired. In order to prove a DWI, the State must show that your ability to drive was “somewhat” imparied.

There is also a crime in Maryland called “DUI Per Se.” More on that later…
