Waving at the bus
If the traffic conditions allow it and there is more than 600 meters between the bus stops, it is possible to get on and of the bus even if there is no busstop.
If you want to get on the bus you have to wave at the bus. At night you have to use a flashlight to get the attention of the driver.
If you want to get of the bus between stops you have to let the driver know in advance. Be aware that the driver solely determines if it is safe to stop at the desired location.
