"(3) Pedestrians must cross roadways quickly and by taking the shortest route perpendicular to the direction of travel, taking care to avoid vehicular traffic. If traffic density, speed, visibility, or traffic flow so requires, a roadway may only be crossed at intersections or junctions, at traffic lights within markings, at pedestrian crossing aids, or at pedestrian crossings (sign 293). When crossing the roadway at intersections or junctions, pedestrian crossings or markings at traffic lights must always be used."
Maybe there's no penalty, but a 6 lane road probably has traffic density/speed/flow enough to get to the "may only be crossed at intersections or junctions"
That law isn't about jaywalking. The concept of the US-english word "jay" doesn't exist ). There is no german language equivalent.
Also, this is one of the paragraphs that is just there. It's not enforced. Do you know any German that ever get fined for it? Is the police out with cameras looking for slow pedestrians? Naa, they are out with cameras looking for too speedy cars instead!
) maybe "Landei" ? But it's never used in traffic context. We simply had a car-lobby creating vile words to modify law-makers behavior like it happened in the USA at ca. 1910.
