Turning right or exiting at the first exit around the roundabout:
Unless posted otherwise, use only the right–hand lane if there are multiple approach lanes. Use your right–turn signal.
Going straight ahead (i.e., exiting halfway around the roundabout):
Turning left or making a U–turn (i.e., exiting more than halfway around the roundabout):

Well–designed, low–speed, single–lane roundabouts should not present much difficulty to bicyclists. On the approach to the entry, signal your intentions and merge into traffic. It is generally safest for bicyclists to claim the lane. Keep in mind that drivers should be traveling at about 15 to 20 miles per hour, close to the speed you ride your bicycle.
Most roundabouts will give you three options:
In Maryland, pedestrians have the right–of–way within crosswalks at any intersections, including roundabouts. However, pedestrians must not suddenly leave a curb or other safe waiting place and walk into the path of a vehicle if it is so close that it is an immediate hazard.
