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

Answer 1 is correct because on a motorway on-ramp you must adapt your speed to the traffic on the right-hand lane and merge without forcing anyone there to brake or swerve. If you are at least 20 km/h faster than the green truck, you can normally merge in front of it safely because you will quickly create a larger gap after merging, which reduces risk.

The key rule of thumb for these questions is: use the acceleration lane to reach motorway speed and then “zipper” into a suitable gap. Choose the gap that requires the smallest speed change and does not make motorway traffic react. If you have a clear speed advantage, merging ahead is usually the safer, smoother option than braking hard to go behind.

The other actions are typical traps: braking to go behind is only necessary if you cannot merge safely ahead; stopping at the end of the acceleration lane should be avoided and is only a last resort if merging is impossible, because it makes joining fast traffic extremely dangerous.
