Virginia has a great number of multi-lane divided highways. The rule is to use the left lane with on-coming traffic very carefully if at all ~ but the right hand side of the road, whether it's 1, 2, 3 or 11 travel lanes like part of I495 near me, is where you are supposed to move left to avoid traffic entering the highway at interchanges.
We can always tell those out of staters by the way they cut you off entering the road. So, a warning, we get to pack heat without a license ~ please be polite and MOVE LEFT to get out the way!
