If there is no pedestrian button, don't push it.
If there are no cars (as stated) then don't follow them.
If you look around before you go to make sure it is safe, you will see if there is a police car. if there is, see @Rsob's post two posts up which completely answers the question.
First step is Always know the bike laws where you ride. They will be online and not too hard to find. (first step, IMO)
