Since "jaywalking" has been brought up. I would like to clearly clarify:
#1 ~ If your a pedestrian in a crosswalk and it is a pedestrian dominant crosswalk (no signal light and cars must always stop for pedestrians always, usually mid-block or no signal light intersection and my favorite type of crosswalk) ~ YOU ARE NOT JAYWALKING, period no but's and's or maybe's.
#2 ~ If your a pedestrian in a crosswalk and you have the walk signal, or in the case where there is no separate pedestrian walk/don't-walk signal or it is not working you are crossing with the green light ~ YOU ARE NOT JAYWALKING, period no but's and's or maybe's.
#3 ~ If your state recognizes "invisible" unmarked crosswalks between the corners of every intersection (some state laws do, others don't) and your crossing with the green light on a signaled intersection ~ YOU ARE NOT JAYWALKING, period no but's and's or maybe's. Laws do differ from state to state as to how "invisible" unmarked crosswalks without signal lights are treated if the state in question recognizes them. In some states on non-signal light intersections the unmarked crosswalks are always pedestrian dominant crosswalks, in others it goes with the traffic signs (for example cross street intersection with a stop sign for the cross street but not the main road the two unmarked crosswalks from corner to corner across the cross street with the stop sign are pedestrian dominant where as the unmarked crosswalks across the main road are not).
#4 ~ Simply the act of crossing the street as a pedestrian where there is no crosswalk (marked or unmarked) is NOT jaywalking, its only jaywalking if you fail to yield to vehicle traffic on the road.
#5 ~ In areas where sidewalk cycling is legal and you choose to do so check your state laws and local ordinances. In some areas you are by law required to dismount and walk your bike when using a crosswalk and if you fail to do so you have no legal protection as normally encoded in law for vulnerable crosswalk users. If its not legal to sidewalk cycle in an area you have no legal protection as normally encoded in law for vulnerable crosswalk users for sure unless you dismount and walk your bike in the crosswalk.
That said, I personally really don't have anything against "jay-walkers" although I won't engage in that behavior myself. It's the "jay-runners" that annoy me especially when they run out from between two parked cars at like only ten to fifteen feet in front of me !!! I've had to lay my bike down or deliberately swerve and slam into a parked car on my bike riding VC style keeping up with cars in the middle of the lane in in-town 15-25mph traffic more then once to avoid hitting them; very obnoxious. When riding VC style in-town in traffic like that I stop for peds. in the crosswalk just like a car or motorcycle should and I don't mind that one bit and the ones that just walk out I can usually swerve into the left part of the lane quick enough if they are really close or brake and slow if they don't walk out right in front of me, but the ones that run out in front of me at point blank range are the ones that are the bad ones because they are like squirrels and you don't know if they are going to continue or stop in the middle of the lane or try to turn and run back so you can't try to dodge them otherwise you and them might dodge the same direction and you still hit them and if the run out so close in front of you you can't stop in time with just the brakes other more drastic means of stopping right away become necessary, as in a controlled crash either laying the bike down or hitting a parked car instead of them. Neither of which are a good option.
