Why do some roundabouts have these markings?
 

There are a few roundabouts that have the inner lane marked with yellow lines in some areas seemingly to guide traffic out of the inner lane. Something like the attached picture. This doesn't make any sense to me. Anyone know the reasoning?

Good question?

So you don’t drive there and make a single lane at that point.

Which immediately forces two lanes into one and seems rather dangerous. My question was what is the reasoning behind this.

Oh no! Another round about thread.

Here’s a couple hundred answers.

No, if you look at the lane markers, the outside lane instructs you to go straight...

Outside lane should only be going straight.
Before you get to the roundabout, READ THE LARGE GREEN SIGN AND NOTE THE ARROWS!

The question is why do some roundabouts transition to a single lane for a left turn but not others?

I believe that it has to do with a one lane exit. Posting #2 has two pictures.
The left picture has the yellow markings at 12 o'clock and 6 o'clock. The exits right after that (at 3 o'clock and 9 o'clock) have a one lane exit. The picture on the right (without the yellow markings) has two lane exits at all four exit posts.

I think it forces traffic into the outer lane if you are planning on taking the one lane exits.

See the link to posting #7.

These are "A striped channelization island is present in several roundabouts, which reduces the circulatory roadway to
one lane approaching a single-lane exit."

Useless post: None of those links answered the specific question.

outside lane should only be going straight?
Which lane should I be in if I wish to turn and exit the roundabout?

I think the answer to the specific original question is that the orange lane marker squeezes the traffic into one lane because the road at that exit point is a one lane road.

Where they don't have the orange lane marker, you can exit from the left lane of the roundabout into the left lane of the road you are entering (e.g. Morse or Buena Vista).

However, for example, at the Morse-Bonita roundabout, Bonita has only one lane to accept traffic from the roundabout, hence the roundabout has only one lane at that exit point.

EDIT: the diagram doesn't display that, but the aerial photo posted in a subsequent post does illustrate it.

Outside lane: 90 degrees or straight
Inside lane: straight or 270 degrees.

perhaps they made the one lane configuration to eliminate the idiots that insist on going 270 degrees around in the outer lane----and that includes the president of the idiots club that previously posted that he always uses the outside lane to go 270 degrees because HE believes it is "safer". Like Judge Judy says, "you can't fix stupid".

The roundabouts without the hash marks indicate that the exit off the main thoroughfare is a two-lane exit. The ones with hash marks indicate the next exit is a single lane.

My question was a rhetorical question, in response to the first above quoted post.

Realized that, my response was general, not directed to your post, but it was convenient.

:coolsmiley:

OK, I see the one lane exit is the answer. Still, it seems like a clumsy way of doing this. Would it not be better to have a solid yellow line between the two lanes at these areas, with arrows pointing straight on the inside lane, indicating you can't make the right turn from the inner lane? Forcing one lane inside the roundabout seems like a dangerous move.

the net of it all is the lane markings of the roundabouts in TV are for the most part poorly lined. I say this as compared to many other municipalities I have traveled through. I also hestiate on this because as I (and many) have seen the driver has no idea the difference between a dashed and solid white line either.....

Roundabout
 

It just means what everyone does….close your eyes and keep going like you always have…no clue how to enter and leave a roundabout!!!!

That was my first guess but there are exceptions.

They also don't have shoulders and the high vertical curbs risk directing a vehicle back towards the other lane if the vehicle goes more than a foot off lane.

Probably why the posted speed limit is 15.

What are you talking about? The outside lane should continue straight. You never continue to go left from the outside lane, just like at a normal intersection you'd never make a left hand turn from the right lane. The inner lane has the option to go straight or left.

It maybe like that because most Villagers don’t know how or refuse to drive correctly in a roundabout!

Notice the dashed lines. There is always the possibility the car in the outside lane will continue and not exit. They should exit if they entered two streets before, but if they just entered at the previous street they can certainly continue. This is why you should never travel with another car beside you.

100)% correct. I've seen dozens of times the kamikaze inside lane car speed up to pass the outside lane car to exit into his/her gate

Welcome back !

Thanks! These "vacations" are getting ridiculous"...

I'm beginning to feel like this guy...

Simple. They are trying to stop the people in the outside lane from cutting off people in the inside line

Roundabouts are an engineering marvel!
 

I have full faith in those who engineered the roads here in the villages. Roundabouts do a great job of keeping traffic moving. I came from a city where there are either traffic lights or a stop sign at every corner. And it’s the last place in America where a right turn on a red light is still illegal.

Not too many things are annoying, to me, as waiting at red light when there is absolutely zero traffic on the cross street. Travel time wasted. When the light eventually turns green one is forced to stop again a block or two away for another red light (let’s not forget the wasted gas and added exhaust fumes added to the air). A seemingly simple drive to the supermarket 3 miles away can take upwards of a half hour! I had to accept this a fact of life for living there. After 3 years here in the Villages going driving in my hometown seems painful.

These roundabouts are a blessing to me! The forced merger mentioned is far better that waiting for a light to turn green.:BigApplause:

Because the next right in the roundabout is a single lane and not a 2 lane road like most of the others.

I've read several times that it is illegal to change lanes in a roundabout even though there are broken lines.

In the https://www.districtgov.org/communit...t-02-08-12.pdf example a car entering from 12:00 in the left hand lane that wants to turn left, (or exit at 3:00), must change lanes. If it actually against the law to change lanes, then the car entering from 12:00 in the left hand lane would only have the option of going straight.

We have a roundabout close to my house with two of these single lane barriers. I've always wondered what the point is.

These are marking meant to help navigate the roundabout safely. This isn't really needed if the driver just looked at the sign before you enter the circle. They feel the markings will keep cars in one lane at the most dangerous park of the circle. Where the person thinks it will be okay makings a right hand turn from the left lane and so forth.

Useless post adding nothing, are you bored?

The "outside lane" should not "only" be going "straight."

In fact, if you were to go "straight" you'd drive right into the island in the middle of the circle.

The outside lane is for taking the very next exit, after entering the circle. It is also for taking the second exit, which would normally be directly across from your entry point on the other side of the circle.

HOWEVER

If there are only 3 exits, and the second exit after entering is 3/4 of the way around the circle, then you should enter the inner lane in order to take that third exit.

(there are a couple of circles that only have 3 exits/entrances - the rest have four)

All exits are right turns. Even that one 3/4 of the way around the circle. When you get to that exit, if that's the one you want to take, you will be exiting the circle by turning right. It's called a left exit, which is ridiculously confusing to anyone who's never had to deal with traffic circles before. It's also ridiculously confusing to anyone who HAS had to deal with them in other states, where those exits are referred to by their directionals, or by numbers (northeast exit, or third exit). Elsewhere, the process of exiting a traffic circle is referred to as "taking a right" or "exiting the circle to your right."

It is because the exit only has one lane. You are correct, they force to lanes into one before the exit. Otherwise, two cars exiting would have a conflict. Even more dangerous.

No such animal as a left turn from a roundabout.

I think this is generally the correct answer. But there are exceptions. The inner circle markings do indicate stay left.

And the other rule that is getting ignored more often----never enter a RB when a car is coming around IN EITHER LANE, for the very reason you just mentioned.
