A roundabout is a circular intersection engineered to maximize safety and reduce traffic congestion. Vehicles travel counter-clockwise around a raised center island with entering traffic yielding the right-of-way to circulating traffic. Slow speeds aid in the smooth movement of vehicles through the roundabout.
Benefits of roundabouts
Optimized traffic flow
Slower vehicle speeds
Improved safety for cyclist and pedestrians
Reduced greenhouse gas emissions
Tips for drivers
Approaching a roundabout
Slow down enough that you can stop at the yield sign if necessary.
Yield to all pedestrians at each approach of the roundabout. If there is a clearly marked pedestrian crosswalk, it will be located in advance of the yield line.
Do not block the pedestrian crossings.
Entering a roundabout
Yield to traffic already inside the roundabout (including cyclists). They have the right-of-way.
Inside the roundabout
Do not stop, except to avoid a collision or to yield to the crosswalk. You have the right-of-way over entering traffic.
Continue until you reach your exit.
Dealing with emergency vehicles
Do not enter a roundabout with an emergency vehicle behind you. Pull over to the right and wait until the emergency vehicle has passed.
Do not stop inside the roundabout; you may block the emergency vehicle.
Exit roundabout at your exit and drive past the traffic island before pulling over.
Tips for pedestrians
Pedestrian crosswalks are clearly marked and located before the traffic yield line. Only at these marked locations.
Do not cross to the center island.
Wait to cross until there is a big enough gap in traffic or all approaching vehicles are stopped.
