You are driving at least 20 km/h faster than the green truck. What should you do?

In German traffic rules, when you are driving at least 20 km/h faster than a slower vehicle (in this case, the green truck), you should merge into the motorway ahead of that vehicle rather than slowing down behind it. This ensures smooth traffic flow and avoids unnecessary braking or congestion on the motorway.

If you were to brake and move behind the green truck, it could disrupt traffic and increase the risk of accidents. Stopping at the end of the merging lane is not allowed unless absolutely necessary, as it can also create hazards.

The key rule is to adjust your speed and position to safely merge ahead of the slower vehicle when you are significantly faster. This approach maintains safety and efficiency on the motorway.
