The Netherlands has so called rush-hour lanes, which are ofter emergency lanes that are opened for traffic during rush hours. It is always indicate with green arrows above the highway. I find it quite confusing on how to get on these rush hour lanes, because to get there you need to get over a strait white line, which in normal condition indicates 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 surpass traffic.

So how should these rush-hour lanes be used? Should you only get on them, when there is an intermittent dividing line and stay on the rush-hour lane until there is another intermittent lane, or should I ignore the continuous line and just change lanes as if it didn't exist?
