This morning I was parked up next to the curb on a long straight 30mph urban road which is moderately busy. I needed to drive off in the opposite direction. The road is wide, but wide enough to U-turn meaning I had to do a three point turn in the road.
I waited until I had a reasonable amount of space clear of traffic in both directions - nothing visible behind me, and a car approaching about 300m away in front of me.
I completed two points of the three point turn and was ready to execute the third point as the approaching car reached me.
At this point, who should give way?
I fully expected the approaching car to adjust their speed so I could drive off ahead, but the car continued without slowing and went ahead of me, which gave me a bit of start.
YABU - the car turning in the road should give way to the approaching car, letting them pass before completing the 3 point turn
YANBU - the approaching car should slow to allow the car turning to complete the manoeuvre.
