Roundabouts are generally a good idea when it comes to easing traffic flow, as they eliminate traffic lights by keeping cars moving more often. They are not, however, great if you're the driver of a semi with a particularly oversize load. Depending on the length of the trailer, in fact, a roundabout may be a wildly difficult obstacle, requiring its own degree of special equipment.

Sort of like this oversize load, which is attempting to traverse a fairly large roundabout. Now obviously, the larger the diameter of the roundabout, the easier it's going to be for a semi to get through, but even this big traffic circle is a challenge. It looks like the trailers each feature their own steering system, and it seems like they can actually pivot independently of the truck's payload (anyone familiar with oversize loads, though, please share your wisdom in Comments).

We have video of the process down below. Have a look and let us know what you think.

      Bah. Idiots in the US think they know something about modern roundabouts because they have seen an archaic old rotary intersection or two. Moderns roundabouts are great and their use in the US is growing rapidly, even as older and totally useless traffic calming rotaries are eliminated.

      Round abouts are generally a good idea? Where the hell did you get that idea. In NJ they have been systematically doing away with them over the years and that's a good thing. They confuse drivers and during very busy traffic times are extremely hard to get through or into. Can't wait until they are all gone.

        Roundabouts work perfectly well in countries where people generally have an aptitude for driving. In the US, roundabouts aren't the problem; poor lane discipline and complete lack of respect for other road users are by far the major issues.

        If a roundabout confuses you then you shouldn't be allowed to drive. We really need to get those kinds of drivers off public roads.

          You speak as if they are all the same. They are not, i spend alot of time on the roads and there are more than one type or style. 1 lane, 2 lanes and even worse 3 lanes. Some have 1,2,3,4 and 5 entrances and exists. Some can literally take minutes to get into if you are coming off of a side road in rush hour. Better yet they are poorly designed to handle any vehicle that isn't completely wrapped in windows. I can see them working in low volume situations, but they just don't on busy roads that typically have 45+ mph. While i manage them fine, i'm also very aggressive. Get a few layed back or cautious drivers and they are a major traffic jam.

        To be fair, I dont think Jcar is talking about normal roundabouts like the one you see here. There are some serious cluster F roundabouts in NJ. The whole NJ road system is a mess the further north you go in NJ. If you're familiar with the exact intersection then its no issue. Not so easy if it's your first pass. They seem to be adding these more and more in my area. Most are fine but its a bit much when they stack them one after the other or when they try to cram two lanes into a small circle and drivers just plow through both lanes.

        Roundabouts have pros and cons. They cost more than lights, but cost less than an overpass. They have more accidents than lights, but the fatality rate of the accidents is very low. They are designed for specific traffic flows. The biggest problem with roundabouts is that municipalities go crazy with them and put them in traffic areas where roundabouts are not advantageous or make them the wrong size for the traffic flow (or the flow changes). The result is frustrating. Lights can have the same problem, but lights can handle a larger variance and can be more easily modified.

          "No matter where you stand in the traffic circle debate though, one thing I think we can all agree on is that traffic circles WITH stoplights are an abomination" HAHA so true waetherman. I'm looking at you Dupont circle roundabout in DC!

        I don't know about the rest of the world, but Houston drivers have a difficult enough time with straight roads.

          upvoted. Originally from Jersey now in Houston. No doubt, Houston drivers are far worse.

      Mounting the gigantic cylinder just at the front & back was a good idea, never seen it done but looks like that's what made the round-about circus possible.

      If round-a-bouts are so great, why doesn't the autobahn have them instead of exit/enter ramps?

        That is absurd, but it's worth noting that both roundabouts and cloverleaf-type entrance/exit ramps share the feature of not requiring anyone in the intersection to stop unless necessary due to traffic conditions. Roundabout is appropriate for low traffic speed, cloverleaf for high traffic speed but it takes more land space. Roundabouts are a substitute for 4-way stop signs and traffic signals, not for motorway ramps.

        People that don't know how to use things most likely blame the things instead of themselves.

      Looks like with all the care they took to just make a turn they should just have gone straight thru the circle and be done with it.
