How to Navigate a Roundabout  

Open to the public airports  
When approaching a roundabout, slow down and observe advisory speed limit signs. Stop for pedestrians in the crosswalk. IT​’S THE LAW.
Takeoffs and landings 
When entering a roundabout, yield to traffic already in the circle. Look left and then enter when there is a safe distance in the circulating traffic.
When at the roundabout, drive counter-clockwise and obey signs at all times.
When inside the roundabout, DO NOT STOP. You have the right of way.​





No. Other than sharing a circular shape, a modern roundabout operates much differently than other traffic circles, including rotaries. A modern roundabout requires entering traffic to yield the right–of–way to traffic already in the roundabout. This keeps the traffic in the roundabout constantly moving and prevents much of the gridlock that plagues traffic circles and rotaries. Modern roundabouts are also much smaller than rotaries and thus operate at safer, slower speeds. The design of a modern roundabout allows capacities comparable to signals but with generally a higher degree of safety.

Roundabouts can offer a good solution to safety and capacity problems at an intersection. At intersections where roundabouts have been installed to replace existing intersections, accidents of all types have been reduced by over 35 percent, and injury accidents have been reduced by over 60 percent. Roundabouts can also offer high capacity at intersections without requiring the expense of constructing and maintaining a traffic signal.

No. GDOT evaluates each candidate intersection individually to determine which intersection type is more effective. However, roundabouts are being utilized nationally under a variety of conditions including: freeway interchange ramp terminals, high speed rural roads, “gateway” roads into lower speed municipalities, frontage roads for schools, roads with awkward geometry, and even along light rail corridors.

Not necessarily. Roundabouts might cost more to install than the actual traffic signal equipment, but if the intersection does not already include turn lanes, the construction costs for either option may be similar. The big savings on a roundabout comes with life cycle maintenance costs.

It depends on the amount of pedestrians and vehicles. In many cases, a roundabout can offer a safer environment for pedestrians than a traffic signal because the pedestrian crossing at a roundabout is reduced to two simple crossings of one–way traffic moving at slow speeds. A pedestrian crossing at a traffic signal still needs to contend with vehicles turning right or left on green, vehicles turning right on red, and vehicles running the red light.

Yes. Roundabouts are designed specifically to accommodate large vehicles. As tractor trailers approach roundabouts, they should stay close to the left side of the entry. As they pass through the roundabout, their trailer may drag over the special apron around the central island – which was designed specifically for this purpose.

It is generally best to completely clear the intersection and pull off to the side past the roundabout. However, if the roadway in the roundabout is wide enough, you may be able to pull as far to the right as possible and allow the emergency vehicle to pass.

A bicyclist has several options at a roundabout, and your choice will depend on your degree of comfort riding in traffic. The speed of cars through a roundabout are typically 15 to 25 mph, close to the speed you ride your bicycle. You can choose to either circulate as a vehicle or use the sidewalk around the roundabout. When circulating as a vehicle, be sure to ride near the middle of the lane so that drivers can see you and will not attempt to pass you. Remember that cars should be traveling at speeds similar to your speeds.

In general, approach a multilane roundabout the same way you would approach any other intersection. A roundabout should have signing and marking to show you which lane you want to be in. If you want to turn left, signal that you intend to turn left. If you want to turn right, signal that you intend to turn right. In all cases, pass counterclockwise around the central island. When preparing to exit, turn on your right turn signal as you pass the exit before the one you want to use.
