I see these every time a bicycle path intersects with any kind of car or train infrastructure. It just seems really patronizing, as if we’re not capable of slowing down without getting off the bike; it also shifts responsibility onto the cyclists if there is a crash based on something arbitrary (mounted vs dismounted).
I like the ones around here which say, “Bicycles may use full lane.”
May? I don’t need your damn permission; that’s already the law on every square inch of road in the state that’s not an interstate highway. Yes, I know that’s more of a reminder for motorists than anything else, but the lack of education there is rather astounding. Plenty of people labor under the misapprehension that bicycles aren’t allowed on the “real” road somehow, and get frothingly butthurt every time they see one.
Our state is a bit archaic on that front. Unless something has changed recently, last I looked our interstate/controlled access highway restrictions still assume that all vehicles will be combustion powered; Bicycles, animals, and any form of conveyance without an engine of at least (IIRC) 55cc is prohibited. So presumably this also lassos all electric vehicles, which don’t have any engine displacement to measure whatsoever. But nobody seems keen to do anything about it.
Beyond that restriction, anything with wheels here is a vehicle. I could roll my office chair down the street and would be entitled to the full set of rights and responsibilities of operating it on the road, including my space in a lane.
Ah, the cities that feel putting up a few ‘share the road’ signs (in seemingly random locations) is a suitable replacement for having protected bike lanes.
