I usually take roundabouts at 20 mph, as I understand that to be the speed limit. I don’t recall seeing anyone take them faster. I stay strictly in the marked lane for where I want to go. Some people try to straighten out the curve by cutting into other lanes. That’s lazy, and it’s a bad idea. I would way that it would be unsafe to take those curves faster than 20 mph, assuming people stay in their lanes.

I did see a dumped over dump truck years ago on Buena Vista going south near the entrance to Tall Trees. It took a dump.

Yes, If in right lane going to turn at first or second exit, nobody will be cutting them off, only when they try to go to 3rd exit it big problem IF traffic in circle.

Turn signals are required by law when making a turn. That is the most likely reason some people use them.
A good use is by Lane 1. When they need to exit a two lane circle, they must cross over Lane 2 to exit. A turn signal tells anyone in Lane 2 that they must slow down and let him exit the circle since Lane 1 has the right of way.
The above is for the two lane circles with both lanes having the ability to exit when "going straight".

For the same reason the older generations use glass packs and cherry bombs.

Neither lane has the right of way. Both drivers have an obligation to avoid an accident.

Importantly, if both drivers are driving properly then there will be no conflict, no right of way to yield, and no potential accident to avoid. If they are not driving properly then all bets are off.

I wonder if any research has been done to compare accidents resulting from the lack of use of turn signals with accidents resulting from trusting a turn signal that had not been turned off.

That would be a great study. While I use my turn signals in a RB, I don't trust anyone else's turn signal and I don't expect anyone to trust mine.

Maybe you could get a government grant for the study?

Vehicles in roundabout has right of way. Vehicle approaching roundabout HAS to yeild to ALL traffic in roundabout. The vehicle in right outside lane either entered roundabout without yielding to ALL traffic in roundabout or vehicle in right (outside lane was going to third exit which is wrong why got cut off. Think about it. If you yeild to all traffic and in right lane exit at first or second exit that situation will should never happen.

One way it *could* happen: Vehicle in the outside races into the circle and overtakes the vehicle already in the inside lane. The vehicle in the outside lane (the one that is overtaking) would still be at fault for causing the conflict.

I went through several roundabouts this morning. Every one of them had a sign after exiting that restored the speed limit to 35.

Broke the yield rule. Racing in not yielding and cutting off traffic in roundabout.

Thanks for the responses to my original post.

For what it's worth, I try to make sure I'm going at no more than 20 mph as I enter the roundabout (that sign is not a suggestion), but I don't daudle in the roundabout - I maintain that 20 mph until after I exit in the appropriate lane (usually the one in which I used the roundabout). Although I believe the 20 mph speed limit on the approach means 20 mph at the sign, I feel the signs are too far ahead of the roundabout entry and would slow traffic more than necessary. I also feel that the primary purpose of a roundabout is to provide equal opportunity for entry from all directions, which requires that all approaching vehicles be prepared to enter at a speed of no more than 20 mph. It seems to me as if those using the "main" roads don't observe this as much as they should.

Many folks seem so intent on getting where they're going that they somehow miss those great big green signs that tell them which lane to use. Many others change lanes as they exit. Why not change lanes after you exit?

My own simple-minded rule that I try to follow is never to be in a roundabout next to another vehicle. That has served me well so far.

I tend to signal my intentions whenever I'm going to do something I'm not already doing. I wore out the turn signal switch in my previous vehicle, but I managed to replace it without triggering the airbag.

I'm only aware of one roundabout that doesn't have a 35 mph speed limit sign after exiting (where the normal speed limit is 35 mph), and that may be an oversight or the result of not yet replacing one that was damaged.

It's interesting to see others' opinions on matters like this. We've probably beaten it to death by now.

You just described the two most common errors made by drivers in the outside lane of a RB. It happens continually every single day. I have learned to expect those things to happen and drive accordingly.

Just goes to show how many idiots there are living among us. Be afraid. Be very afraid! Drive accordingly!

This is too funny.

You caught that too….

Sums it all up really.

My favorite is the people who flatten out the circle , entering in the outside lane , move to inside lane in the circle then exit in the outside lane

What's even more fun is when they clip the inside curb with their driver's side wheels. They're the same driver's that cross 10 feet into oncoming traffic to pass a golf cart in the cart lane or come near the inside curb when making a left turn

The best thing to do is enter the roundabout at about 45 mph, change lanes several times, then act like everyone else is the problem. Just my bit of sarcasm.

I thought you were serious! I see it all the time.
