If I were to come to a T-juntion in Doha I would give way to traffic coming from my left until a space to either turn right and go with the flow of the traffic from the left, or to wait for a space to cross the road and turn left and so join traffic flowing to the left, surely!

So I guess, in theory, you should give way to traffic coming from the left.

If by intersection you mean a cross road, then I guess just keep your eyes peeled to the left primarily then put your foot down lol
