If this quote in the article below is accurate, it is now legal everywhere except VT.
"Virginia will become the 49th state to accommodate two-abreast riding. Vermont remains the only state to prohibit the practice."
Here is a link to the article I pulled it from.

well, the timing of the passage for the law change, occurred just after I moved back to Ohio...
I do know the whole ridiculous law was being voraciously opposed to by my attourney's firm, as they spearheaded numerous law changes in the last 15+ years... extremely good attorneys, that cared about motorcyclists more than just making a $$$$ on it.
https://motorcyclelawgroup.com/Tom's brother Joe, represented me in another case, and in talking with Tom, he did tell me they were actively pushing for the 'two bikes / one lane' repeal...
that was in 2010-2011.
they did push thru the 'm/c allowed in H.O.V. lane' law revision, which was another stupid restriction on m/c riders travelling the D.C. corridor on Rt 95.
I do know for a fact tho, that prior to my move, it WAS a moving violation to be paired up at a stop light/sign/intersection; I was sitting in the right half of my lane (left lane, for left turn on arrow signal) at a light, waiting for a clear shot to turn left, correctly positioned, and had some Pirate roll up next to me on the left, so he could take advantage of the turn when I turned, simultaneously... and when we both turned, about 200 feet down the road we were stopped by a local LEO, who was sitting at the intersection..watching it all happen..while talking on his cell phone....
(who by the way, turned on his lights, and siren, just so he could run the red light he was sitting at, to catch us, and ticket us..)..
I talked my way out of it, as I explained "I did nothing wrong... ticket the other guy....I don't know him from Shirley Temple, and as you clearly watched him roll up in place, and complete the turn, and pursued to accommodate, it's a no brainer", which he promptly did... and I lucked out... I guess being fully geared up, and older, and on a quiet proper motorcycle may have played in also...
I've never been a proponent of side by side riding, even here in Ohio, and I can count the number of times where after stopping behind someone I was riding with, slowly rolled up adjacent to let them know something, but never pulled away from a light simultaneously. I still stop behind a stopped rider, set off to the side so I can see their face and eyes in their mirror (so I know they can see me), every time I come upon this scenario.
