This is not a typical roundabout. You can only go left or right in the example you provided. In a typical roundabout the right hand lane is not a right turn only.

That’s because there is nowhere else to go on those roundabouts yet.

Insane!!
 

So I am traveling straight thru and approach the roundabout. The vehicle in the inside lane decides to take the first exit (might even signal his intent). I now need to be wary of that vehicle. Understand but would love to know why they changed to this signage.

Those two roundabouts are right turn or U-turn only. Once roads get connected allowing driving straight through or exiting to the left you will see those signs replaced.

A two lane into a two lane, the only exit apart from a U-turn, what is so complicated or the problem?
This is a wind up posting.

At the RAB in the original post there is no straight thru. It appears to be a one-lane RAB with the left lane entering the RAB and the right line being a right turn only.

With only a single lane in this RAB there is no inside lane. The ONLY lane of this RAB is allowed to exit to the right or continue around.

In "normal" two-lane RABs, vehicles entering from the left lane/inside lane are not allowed to take the first exit. It would be no different from making a right turn from the left lane of a four-lane highway. If they attempt this then they will possibly cause an accident.

With high traffic and unfamiliar roads and the signs posted so close to the roundabout, there is no leeway to choose the lane you need in time (nor should you change lanes while in a busy roundabout). Why aren't the signs also placed further back to help unfamiliar drivers. Not all roundabouts are the same. Arrows in each lane would be beneficial also.

Personally, I like that system better than what happens (confusion) in the central and northern Villages. I have often maintained that the road should merge into ONE lane BEFORE entering the ONELANE roundabout. Some people say that that would slow things to a crawl. I say that as long as there is vehicle movement (not stopping) then the roundabout is BETTER than a RED light. And we would have less accidents with my proposal. AND since we are most all retired we should be able to mentally handle a slow and safe roundabout EXPERIENCE. People know HOW to MERGE, but a 2-lane roundabout is FOREIGN AND AWKWARD to new arrivals.

Nice example OP - thanks!

There are several special roundabouts throughout TV - gotta look at the signs for each.

44A Eastbound at Buena Vista is another - left lane must turn left - only right lane can go straight.

There’s a roundabout in Jacksonville that is one lane like you described. It backs up for miles. People get so frustrated waiting 20-30 minutes just to reach the roundabout that they start taking way too many chances pulling into the circle so close to the other cars that accidents still happen. This, being your solution isn’t as great as you think it is and accidents still happen.

Apples to Oranges
 

It seems like this is an apples to oranges debate. This is not a typical roundabout. If you obey the traffic signs and enter when there is no traffic coming, you should be good.

Thats because there is no going straight. You go to the right with both lanes, the lane on the right can only go right. The lane on the left or inside lane cane go right or left. Try going left from the right and your in for trouble.

Maybe you’re the one that confused?:pepper2:

There are no other exits!!!

I believe it because Jacksonville is a pretty wacky overcrowded city. Even so, I would SUGGEST that if ANY kind of roundabout backs up that MUCH then it is time to put in a RED light. I think of roundabouts as being BEST suited to small towns without much traffic. They become LESS useful here in the high population times like Dec through Feb.
