I thought it was 100', but regardless, yes, there is a zone of "no lane change approaching an intersection". Former member APS reminded us a few times. Sometimes you will see the lane markers change from dashed to solid near the intersection, but I haven't seen that around here.
Maybe actually getting some facts on the table would help.
The Maryland Driver's Handbook
says "You should avoid drifting across lane lines and making lane changes within an intersection." First of all, the Handbook is not a legal document, and you cannot be charged with violating the Handbook; you can only be charged with violating the law itself. (You could be charged with doing something unsafe, but that's a separate aspect of the law.) Second, even if the Handbook were legally binding (which it's not), "avoid" is not the same as "may not" or "shall not".
From TrafficSchoolOnline.com, "Lots of drivers don't change lanes while driving in the middle of the intersection because they believe it is against the law. Even though this is good practice, as changing lanes mid-intersection can be dangerous, a lot of states don't consider it an unlawful act. Still, some states, like Ohio, do consider it illegal."
As an example, Virginia marks most intersections with solid white lines approaching the signal, but Maryland typically does not. Naturally, in any state you must obey these lane markings where they do exist.
Note also that nothing in the Driver's Handbook OR the law says how to use a median crossover intersection.
You may also be surprised that changing lanes without using a turn signal is NOT illegal in Maryland, although in 2009 an attempt to make it illegal was attempted and failed in the state legislature.
You are, however, required to signal at least 100 ft before TURNING at an intersection.

If you disagree, feel free to quote "chapter and verse" of the MD Transportation Code to support your opinion. I suggest the Justia.com website as the most useful. I've searched extensively; I always do before entering into these discussions. I'd love to know if I'm wrong based upon the law itself. But your personal opinion or logic will not sway my trust in the law's specifics, because the law is what can convict me, not your opinion.
