The clip, recorded from inside someone's car using a dashboard camera, was posted on Reddit with the caption: "New Roundabout vs. Old Habits."
It shows the car approaching the roundabout, slowing down as it gets closer.
In the distance, another vehicle coming from the left suddenly whizzes past, driving straight across the roundabout.
Another swiftly follows, as other cars are forced to pause for a moment before knowing how to proceed.
After being shared yesterday, it has gone viral - racking up 7,500 upvotes and hundreds of comments.
One person wrote: "That's ... that's not how those work..."
Another commented: "I love how it took everyone like 5 seconds to think like 'ok weird' and then drive away. EVERYONE."
A third person said: "Time to put some bollards around the perimeter. Or a giant boulder in the middle. Or an 8" curb."
Another suggested: "Just put a ramp so at least they get some sweet airtime."
While the person who shared the video did not specify where it was recorded, it looks as though it's the same one that was causing havoc earlier this year in Rowan County, Kentucky.
A video was posted by Walker Construction back in April, which used the footage as an example of how NOT to use a roundabout - this one being the first to be installed in north-eastern Kentucky.
In the video, cars can be seen taking the wrong exits, or sometimes even heading completely the wrong way around the roundabout.
At the time, a local called Jason Whisman told news outlet WYKT: "It's going to throw them for a loop. A complete 360. No doubt about it."
According to data from the Insurance Institute for Highway Safety, roundabouts cut down on crashes by 38 percent and fatal or incapacitating crashes by 90 percent, by significantly removing the chance of a head-on or T-bone collision.
They are also greener, as cars don't have to stop or start as much when using them.
Another driver told the outlet: "I've seen a number of accidents here in the past.
"People just don't pay attention to the stop lights or signs in general. So I think this will do very well, provided people actually read the signs."
