Police officials will crack down on drunk drivers Friday night with a roaming DWI enforcement initiative.

The effort will take place across the city from 8 p.m. until 6 a.m. Saturday morning, police said in a statement. They said they plan to stop motorists to ensure their ability to drive has not been hampered by alcohol or drug use.

The maximum penalty for a DWI conviction in Virginia is a 12-month jail sentence, a $2,500 fine and a yearlong driver’s license suspension. There are also mandatory minimum jail sentences in place for different blood alcohol content levels.
