Okay, now what about left turns where cross street has two-way left-turn lane?

Factual Questions

Okay, next question about turns and lanes.

Some streets have a two-way left turn lane in the middle. When you make a left turn from such a street, you are supposed to start it from that lane.

When you make a left turn into such a street, you are supposed to complete your turn into that lane. But I’m not sure how strictly true that is. The usual rule is, when you make a left turn, you can turn into any lane that is safe to turn into.

When I make a left turn, where the cross street has a two-way left turn lane that I could turn into, I don’t always do that. If there is no cross traffic, I often simply turn directly into one of the driving lanes. I’m not sure how legal that is, and I’m also not sure if anyone (cops in particular) take that very seriously.

Anyone have any knowledge (or experiences) with that?

I don’t think you’re supposed to turn into the shared center lane. In WI you’re supposed to turn into the closest travel lane, then signal a lane change if you need to get over to the right if there are multiple lanes in your direction. The only time I see people turn into the shared center lane is when traffic is heavy and you get an opening to clear the traffic from your left first, then wait and merge into your desired lane when you get a chance. Probably not strictly legal, but sometimes it’s the only way you can get out.
