ROUNDABOUT INTERSECTIONS


General Information
Roundabouts are a traffic control device that may be used as an alternative to signalized and all-way stop intersections. Statistically roundabouts are safer than traditional intersections because they reduce fatal and injury crashes by reduction of speeds and removing left-turns in front of opposing traffic. A roundabout uses a circular island in the center to control the flow of traffic through the intersection. Roundabouts feature yield traffic signs at all entering roadway legs. Yield control creates efficient traffic flow and often less delay at the intersection. They reduce pollution and fuel use due to fewer stops and hard accelerations. At a roundabout, drivers who approach the intersection make a slight right turn to go counterclockwise around a circular center island. The driver may then either exit the roundabout onto a different roadway, or continue on the same roadway. When approaching a roundabout, always yield to traffic in the circle, bicyclists, and pedestrians in the crosswalks.

Approaching the roundabout:
Slow down before entering the roundabout.
For multi-lane roundabouts, observe roadside signs and pavement markings to direct you into the correct lane.
Look to your left as you drive towards the entrance, yield to traffic already in the roundabout, bicyclists, and pedestrians in the crosswalk.
Enter when there is a gap in traffic and merge with the other flow of vehicles.
NEVER make a left turn to enter a roundabout.

Traveling through a roundabout:
Always stay to the right of the center island.
Vehicles within the roundabout have the right of way.
DO NOT stop within a roundabout unless it is the only way to avoid a crash.
DO NOT change lanes within a roundabout.
Give special consideration to trucks, trailers and other large vehicles.
They may need to utilize more than one lane within a roundabout.
DO NOT attempt to pass any vehicles especially large trucks.
If you miss your exit, continue through the roundabout until you reach your appropriate exit.
When exiting, watch for pedestrians and bicyclists crossing the street.

Exiting the roundabout:
Maintain a slow speed to avoid losing control or striking traffic islands.
Use your right turn signal to let others know you are exiting.
Do not accelerate until you are beyond the pedestrian crossing at the exit.

Emergency Vehicles
Always yield to emergency vehicles. DO NOT enter a roundabout if an emergency vehicle is approaching. NEVER stop while inside a roundabout. If an emergency vehicle approaches while you are in the roundabout, exit immediately and pull to the right.

Truck Apron
Large trucks need more space when driving in a roundabout. A truck apron, also known as off-tracking, is the paved area on the inside of the roundabout for the rear wheels of large trucks to use when turning. Truck aprons are not to be used by cars, SUVs or pickup trucks.
