A)Stopping before the sign.
B)Accelerating because I am not obliged to give way.
C)Giving way to vehicles travelling on the dual carriageway.Correct
When joining a dual carriageway or motorway, it is mandatory to give way to vehicles already travelling on the main road. You must use the acceleration lane to reach an appropriate speed that allows you to merge safely. You should only stop at the beginning of the lane if strictly necessary due to traffic conditions.
