There's a roundabout near my house that I'm forced to circle regularly. I enter the circle with fear every time because I never know how close to an accident I may come that day. The other day I was cut off by a BMW traveling the entire circle in the outer lane when it occurred to me -- how would anybody in this country understand how to use a roundabout when there's nobody teaching it? If you are among the many who don't exactly understand the great traffic circle, check out this quick tutorial on how roundabouts work along with a long-winded monologue on traffic signals and roundabouts in history.


No one understands Roundabouts in this country, therefore the should not be used on our roadways.
That’s right, Emory – we should never do anything new whether its an improvement or not because we can’t be bothered to learn…
Roundabouts are the safest intersections you can imagine. It IS too bad so few people know how to use them.
There’s really only two critical rules:
1) In the USA, turn right onto the roundabout.
2) Vehicles on the roundabout have the right of way. Don’t enter until you see a clearing.
If it’s a multi-lane roundabout, you can add to use the inside lane until you are past the last turnoff before the one you want to use
Also I think “light turn signals” are very important also in such intersections. Not signaling your intentions may cause a little confusion
Roundabouts are better than traffic lights but the problem I have found is that the roundabout circles are too small in diameter which means that when traffic is heavy it is too hard to enter. If the circle was twice as big thing would work well.
