Since it's not marked at that intersection, I would be safe and turn into the outer right lane if I was in the right turning lane. If you're trying to get on MoPac from that intersection, you should really be in the left turning lane anyway (There's a reasons it's more congested.) My advice is to take the left turn lane and wait a little longer to avoid this conflict you seem to be having.

Also, don't you have to change lanes fairly quickly after the turn to get onto MoPac if you're turning from the right turn lane?

On another note, I too wish the city would mark more of these odd turn intersections. William Cannon westbound turning left onto Southwest Parkway doesn't have a stripe either. I always follow the stripes (if there are any) and avoid turning into the center lane.

Just about 2 miles from the intersection in question is the Southwest Pkwy/Mopac intersection which is also part of my daily commute. There are two turning lanes there that turn into a two lane road and they are marked with dotted lines to keep the left turn lane in the left lane and the right turn lane in the right lane. All the double turn lanes in the Mopac/290 cluster have dotted lines in fact. I'm confused I suppose as to why it would be any different at a similar intersection just a couple miles away.

Do you know any marked intersection in town where the leftmost left turn lane is forced into the left lane and the rightmost left turn lane can choose center or right? Like I said I can only think of the opposite... when there are two left turn lanes, and markings in the intersection, the right turning lane always goes to the rightmost lane, and the left turning lane can choose. I'll admit it's ambiguous when unmarked if there's no law, I'm just trying to guess what an informal convention would be or what people should expect.
Two lanes turning left from Great Hills Trail on to Jollyville road....

Two lands turning right from Bee Caves Rd. to SH71....

Paint on both of these intersections indicate what lanes to follow but not all drivers do.

That perfect world wouldn't have big rigs who necessarily need the longer radius and more sweeping arc in order to turn safely. It would be great if all the intersections could be effectively marked; but as others have mentioned, drivers will do what they want to do. I don't see the necessity of encouraging the oncoming right turn folks to roll the red light so they can pull into traffic turning off a >50mph access road or highway.

ok, that's definitely one


I just found a tidbit from the Texas driver's handbook: "Making a Left Turn From a Two-Way Into One-Way Street: If you are turning left onto a one-way street enter the street in the left lane." So there you go. OP is correct by that metric. But still, the drivers handbook is advice and not law, so if two left-turners crash in the center lane it may be a tough fight with insurance about assigning blame. Hopefully someone can turn up something more legally concrete.

The 'two lanes turning into three available lanes' is its own "kettle of worms"(or is that "can o' fish"?). The two lanes turning into TWO available lanes is pretty self-explanatory; but folks can't even seem to get that one right
The very clearly marked turn lanes from 620 eastbound access road to northbound Parmer Ln have absolutely NO effect on the drivers who just simply want to change lanes or cut the corner or whatever the heck it is they are doing .

That double left turn lane is relatively new and a few people that do not use it frequently may not have noticed the change. Also, the traffic that is making that left turn basically has three options - enter Mopac continue on the frontage road, or stick to the right and enter BC mall. Some animosi probably arises from cars that take the outer left turn lane into the center lane and then 'force' their way into the line of traffic entering the almost immediate Mopac entry ramp. There really isn't much room and two lanes of traffic is a bit tight entering mopac.

That said, any common sense would indicate that the inside left turn lane really should only be people planning to enter mopac and not for people planning to change lanes to their right.

My assumption is that it is safest to cross as few lanes as possible, so the left-most should turn into the left-most to avoid crossing any lanes (other than the oncoming lanes, which should have a red in this case.) But I can't quote the law.

Has anyone gotten any concrete information on this? I am curious to know who has the right to take the middle lane if there are no dotted lines to guide.

Thanks,
Ryan

I have had that happen a lot too, especially at West bound William Cannon turning onto Hwy 71/290. I have gotten where I expect it anymore. There are simply too many morons on the road that don't pay attention to the signs and simply assume there is only one left turn lane where there are actually two. I usually either try to get the jump on them turning if I am first car at the light so they can clearly see me, or hang back a bit and be ready to brake so they can't turn into my car. You can't control the morons on the road, all you can do is try to drive defensively.

Just checked the Texas Drivers Manual on this and I can see what part of the problem is. It indicates when there is only one left turn lane into a road with two lanes going in your direction that it is OK for the driver to turn into either the left turn or the right turn lane. It says on Page 6-6 How to make a Left Turn: "4. Complete the turn to the right of the centerline of the road into which you are turning by entering the lane in which you will interfere the least with other traffic."

and it has a diagram showing arrows indicating you can turn into either the left or right lane. I could find no separate description of what to do when there are two left turn lanes.
