After 120 posts on this thread already, I thought I'd add my two cents worth. I follow 2 rules of thumb in dealing with roundabouts.
1) Vehicles already in the roundabout have the right of way. Respect this when entering and even after entering.
2) Do not pass or pull alongside other vehicles when traveling in the roundabout.

If people followed these principles I think accidents would be minimized. But I never drive with the expectation that other people will follow my rules or that they will use common sense. I am especially wary of what others are doing when I am in these roundabouts.

Overall I think they are great for maintaining traffic flow. Just my opinion.

Agree on all counts, zonerboy.

I was wrong!
 

CF and others posted that the dotted lines mean you are allowed to change lanes. Someone else (can't find the post) said it's the law.

Not only is that correct, you are also allowed to pass. Federal highway markings.

United States Pavement Markings - FHWA MUTCD

So while the brochure says don't change lanes and everybody says never get beside another vehicle, there's no law against either in sections of the roundabout where there's a broken line, which is 50-60% or so of the time in most roundabouts.

I'll be dipped.:22yikes:

I have found it works best to use the signs to determine which lane to use and forget whether the lines are solid or dashed within the RAB.

Yes, you are right. That's what you're supposed to do.

It wigs me out that federal laws allow lane change and passing across broken lines, while federally sponsored roundabout "best practices" instructional materials tell you not to ever do it.

To help understand. Wig Out
From the Urban dictionary..............
To suddenly become unnecessarily worried, anxious, upset, or paranoid most often while under the influence of an intoxicating substance--especially marijuana.

Sometimes refers to a more favorable drug-induced mood change such as suddenly experiencing uncontrollable laughter, though the term "geek out" is more appropriate in this case.


:wave:

Are you suggesting that there should be traffic lights at every rotary or are you suggesting a few with stop signs at several? If stop signs, how would one navigate a left turn, cross 4 lanes, 2 north and 2 south. Or, would one turn right and go to the next light and make a U turn. Of course there would have to be a left turning lane. This would make BV 6 lanes total. There are 13 roundabouts on BV from 466A to 466 and there would be a total of 15 traffic lights.

LOLOL!! this from the English Daily...
wig out
Definition:
To go crazy; lose your mind.

Example:
1) Maria wigged out when she found her husband in bed with her best friend.

Etymology :
The idea behind the term is that so much activity is going on in your brain that your hair ( a 'wig' is artificial hair ) might jump off your head. The term can be positive too - you might 'wig out' when you hear really good music, for example.

Hey Bogie, I'm almost done with this topic. Hoping to get data on roundabout accidents from Sumter S.O. on Monday and then ask for review from public works engineering dept.

You may be, how do you convince others to stop posting the same thing over and over??

BONANZA Any reply?

There usually is....................

Bogie, I think you are wigged out over the fact that we are discussing this. :loco:

You think YOU have problems with round-a-bouts? Check the Swindon round-a-bout in England. AND, you have to drive it on the left hand side of the road.

This is the model being used for the new roundabout going into Fruitland Park Square, in case you missed it earlier.

We should bring the Mythbusters to a Villages roundabout.
