This is an old question that is no longer in use.
Images may be missing and the information may be dated.
You are driving the car from which the picture is taken and have just overtaken a car. Should you change back to the right lane?
All types of manoeuvres entail increased risks. If you change to the right lane, you must check the car behind that you overtook. You then have to complete a lane change again after a few metres. It is true that you normally have to keep to the right lane, but in this situation it is clearly better to stay in the left.
The railway crossing does not have any direct regulatory impact on changing lanes.
