Click on the following links for how to use a roundabout while:
Turning right or exiting at the first exit around the roundabout:
Use only the right–hand lane if there are multiple approach lanes.
Use your right–turn signal.
Going straight ahead (then exiting halfway around the roundabout):
Turning left or making a U-turn (i.e., exiting more than halfway around the roundabout):
If you approach a roundabout in a car, do not overtake trucks and buses. Large vehicles swing wide on the approach or within the roundabout. Watch for their turn signals and give them plenty of room, since they may obscure other drivers' views.

To negotiate a roundabout in a truck, you may need to use the full width of the roadway, including mountable aprons if provided. Be mindful of all other users in the roundabout. Before entering the roundabout, note that you may need to occupy both lanes. Signal well in advance and make sure that others see you and are giving you consideration.
Well-designed, low-speed, single-lane roundabouts do not present difficulty to bicyclists. On the approach to the entry, signal and merge into traffic. It is safest for you to claim the lane. Keep in mind that drivers in the roundabout should travel at 15 to 20 miles per hour, close to the speed you ride your bicycle.
Roundabouts give you three options:
If you are a pedestrian you have the right of way within crosswalks at any intersections, including roundabouts. Do not suddenly leave a curb or other waiting place into the path of a vehicle if it is an immediate hazard.
