Earlier quoted context omitted.
Basically it means that pedestrians are allowed to cross the road anywhere, anytime, but they still have to yield to car traffic except at pedestrian crossings without a semaphore or at the Walk signal. It's a very common-sense law.
> they still have to yield to car traffic except at pedestrian crossings without a semaphore or at the Walk signal. This isn't true. Car traffic must yield to pedestrians. Pedestrians don't always have the right of way, but you (hopefully obviously) can't just arbitrarily mow them down. The only time this would matter is if you hit someone and it went to court. Thus in practice, you have to yield to pedestrians whene…
The same is true with pedestrians crossing where they have to yield to cars. It's their responsibility to check that no cars are passing before crossing. At a crosswalk, drivers will slow down if they see a pedestrian heading towards the crossing; they don't need to (and won't) at other places. Of course, if they see a pedestrian in the middle of the road, they are not allowed to hit them, just like they're not allowed to hit a car.
