Philadelphia City Parking
The PRCL has had several threads on the topic of street parking motorcycles in Philly.
According to the City's Mayor's Office of Strategic Planning they have no on street motorcycle parking policy. The City considers an automobile as far as parking meters, and other parking regulations. Parking on sidewalks is dealt with on an ads hoc basis: if the abutting property owner shows no concerns and there is no undue disruption to pedestrian traffic, then motorcycle parking is condoned. Most motorcycle parking in Center City is handled by off-street lots and garages, each of which has its own policies in that regard. According to the Mayor's Office, the bottom line is that motorcycle parking has never been perceived as an acute issue, and thus it "hasn't garnered much attention."
Additionally, neat piece passed in 2001 making it illegal for a subordinate government to have a low prohibiting multiple motorcycle parking per spot in parallel spots.
Passing on double yellow has been a subject of much discussion. According to Consolidated Statues Title 75, Section 3305:
No vehicle shall be driven to the left side of the center or marked center line of the roadway in overtaking and passing another vehicle proceeding in the same direction unless the left side is clearly visible and is free of oncoming traffic for a sufficient distance ahead to permit the overtaking and passing to be completely made without interfering with the operation of any vehicle approaching from the opposite direction or any vehicle overtaken. In every event the overtaking vehicle must return to an authorized lane of travel as soon as practicable and, in the event the passing movement involves the use of a lane authorized for vehicles approaching from the opposite direction, before coming within 200 feet of any approaching vehicle.
