On my second test the examiner told me to take the next left at the roundabout. I signaled, positioned myself perfectly...to take a right. As we exited the juction he grabbed the steering wheel with his right hand and said "left! not right!" I took a sharp intake of breath but gained control of the vehicle. He asked me to stop the vehicle and explained he was new to the area and was following the test route on a map. I replied I still didn't think it was a great idea grabbing the steering wheel like that. He apologised and carried on with the test which went without fault.
I passed.
