You are driving a vehicle combination consisting of a passenger car and trailer that is more than 7 meters long. Which lanes will you use on this road outside a built-up area if you are traveling at 80 km/h?

Correct answer: The right lane and the lane immediately next to it, if circumstances allow.

Vehicle combinations longer than seven meters must normally use the right lane and may use the adjacent lane if circumstances warrant it, without obstructing those behind. A speed of 80 km/h meets the minimum of 70 km/h required for that lane.
