Drivers who do not understand the new rules appear to err on the side of caution, and wait to turn left. If I'm waiting to turn right I often have to wave to left waiters to indicate they have the right of way. This is getting a bit tedious but hardly dangerous.
It is a bit concerning there are large numbers of people not getting exactly how the new rule works for a free left turn but at least (it appears to me) the same people are not applying the previous rule when turning right.
Is more promotion of the new rule needed? How has the change been for you?
