If you turn left at this intersection, do you have the right of way over the vehicle approaching from the left?

Why?

The A-5 crossroads warning sign indicates a junction of roads of equal priority, where you give way to traffic from the right. The yellow vehicle approaches from your left, so you are on its driver's right and that driver must give way to you. Turning left does not change your priority over that vehicle.
