The Netherlands has so called rush-hour lanes, which are often emergency lanes that are opened for traffic during rush hours. They are always indicated with green arrows above the highway.
I find these confusing because to enter them you may need to cross an unbroken white line, which in normal condition is indication that you should stay in your lane. At the same time, Dutch road laws require drivers to stay on the right and only use the other lanes (middle, left, etc) to overtake.
So how should these rush-hour lanes be used? Should I only get on them where there is an intermittent dividing line, and stay on the rush-hour lane until there is another intermittent line, or should I ignore the continuous line and just change lanes as if it didn't exist?
