Making it hard for drivers to find an answer

I took a long drive to Philly on Monday night in order to exhibit at the Manayunk Arts Fest this weekend and on the way there my darling girlfriend and I had a driving question – what’s the difference between a solid white line marking and a double solid line marking? Checking the Virginia driver’s manual confirmed what we thought about the solid single white line: lane changes are discouraged, but not prohibited. No mention of double white lines, but then again we saw them in Maryland – in Fort McHenry Tunnel, to be exact – so perhaps the MD driver’s handbook is the place to check.

Well, I came up with a goose egg on that one too, but not before noticing something annoying. I opened up the PDF and searched for “white line” and got no results. Okay, “white” then. Zip. Hmm. “Yellow” was also zero, as was a word I could see in front of me on the page I was looking at. They’ve published the handbook with no search ability at all. Hope you want to read it front to back, not find something specific.

Anyway – anyone have a definitive answer on the double white line? I assumed it meant lane change prohibited but it would be nice to have a canonical answer…

    Not an official answer but my understanding has always been double lines mean lane changes prohibited. The reason the double lines are white in that tunnel is because travel in both lanes is in the same direction. Yellow lines are only used when travel is in opposite directions.
