In this situation, should you exercise special caution and, if necessary, stop?

In the video you are driving in fog along a road outside a densely built-up area; in front of you a cyclist is riding at the right-hand edge, a car is coming from the opposite direction, and in the distance you can see the posts and signals of a level crossing. With visibility this limited, you must exercise particular caution and, if necessary, stop. The answer is: yes.

The Road Traffic Act requires you to exercise particular caution when driving in reduced visibility caused by fog, and also when approaching a level crossing, and to drive at a speed that allows you to stop when a safety device or a signal prohibits entry. In fog you see the cyclist and the level crossing signals only from close up, so you slow down, switch on your dipped headlights (low beam) or fog lights, stay behind the cyclist without overtaking while the car from the opposite direction is passing you, and are ready to stop before the tracks.
