Are you obliged in the visible situation to exercise special caution?

In the photo you are driving at dusk, in poor visibility, along a wide city street behind a dark car that is braking; on both sides there are signs B-23 "no U-turns", on the right there is sign D-1, and you can see a junction ahead of you. You are obliged to exercise particular caution. The answer is: yes.

The Road Traffic Act requires a driver to exercise particular caution when approaching a junction, and also when driving in conditions of reduced visibility caused by fog, precipitation or other causes; it also requires you to keep the distance needed to avoid a collision if the vehicle in front brakes. Particular caution is more than ordinary attention - it means increasing your alertness and adapting your behaviour so that you can react quickly enough to changing conditions. The cars in front of you are already braking, and the twilight and haze reduce visibility. You slow down, increase your following distance from the dark car and make sure that your dipped headlights are on.
