You intend to turn left at this intersection. Are you obliged to give the right of way to a vehicle approaching from the left?

Why?

At this equal-priority junction, the give-way-to-the-right rule applies. The driver approaching from the left has you on their right and must give way to you, even when you are turning left. When turning left, however, you must give way to oncoming vehicles travelling straight ahead or turning right.
