Driving behind the heavy vehicle in the given road conditions, obligate you to:

- The road conditions do not require any special conduct.
- Drive closely behind the heavy vehicle ahead.
- Keeping distance is not necessary because the speed is anyway slow.
- Correct answer: Keep your distance, drive slowly and patiently.
Why this is the answer
The correct answer in the official bank: Keep your distance, drive slowly and patiently.
A heavy, loaded vehicle drives slowly and blocks your view ahead. Keeping your distance lets you see the road and stop safely if it slows down or brakes, and this holds true even when the speed is low. In such conditions, drive slowly and patiently, and do not try to overtake when visibility is insufficient.
