- Correct answer: The road tanker driver doesn’t keep to the right of the roadway, even though he can not see the vehicles coming from the opposite direction.
- The road tanker driver is driving far from the “soft shoulders” and in this way avoids risks.
- The marking on the roadway is not clear enough.
- The road tanker driver is driving correctly in the middle of the road, so that he can see better the vehicles coming from the opposite direction.
Why this is the answer
The correct answer in the official bank: The road tanker driver doesn’t keep to the right of the roadway, even though he can not see the vehicles coming from the opposite direction.
Drivers must keep to the right of the roadway, especially before a bend where they cannot see oncoming traffic. The tanker is driving close to the centre line, so a vehicle coming around the curve could hit it head-on. Soft shoulders are no reason to drive in the middle. Stay on the right side of the lane without going onto the shoulder. The road marking is clear.
