Md. electric car drivers may use HOV lanes in the state regardless of number of passengers

Drivers of electric vehicles, and some plug-in hybrid vehicles, in Maryland can once again use HOV lanes on Interstate 270 and Route 50, as long as they get and display a Maryland HOV permit. Because of legislation passed in Annapolis in the last session of the Maryland General Assembly, owners of electric vehicles who display their permits can begin using HOV lanes even when driving by themselves.
