Which cars are turning correctly here?
When you turn, you should cross as few lanes as possible unless signs or pavement markings indicate otherwise. That is, you should turn left from the left lane and turn right from the right lane, and you should turn into the closest lane of traffic that is moving in the right direction. Here, Car A has incorrectly turned into the far lane. Car B has turned correctly into the closest lane. [Turning, Chapter 4 â Driving Rules, Montana Driver License Manual]
