Approaching and entering the roundabout: Slow down and be prepared to yield. Decide as early as possible which exit you will need to take so that you get into the correct lane.
When you get to the roundabout yield line, yield to approaching traffic circulating from the left. Don't enter the roundabout next to a vehicle already in the roundabout because the vehicle may be exiting at the next exit. Wait for a gap in the circulating traffic before entering.
Within the roundabout: Always keep to the right of the center island and travel in a counter-clockwise direction. When in the roundabout, you have the right-of-way over entering traffic. Don't stop when in the roundabout except to avoid a collision.
Do not change lanes within the roundabout except to exit.
Exiting the roundabout:
Maintain a slow speed upon exiting the roundabout. Always indicate your exit using your right-turn signal. Watch for and yield to pedestrians waiting to cross or crossing the exit leg.
Motorcycles and bicycles:
Give motorcycles and bicyclists plenty of room and show due consideration when they are traveling in the roundabout. Motorcyclists and bicyclists should follow the same procedures as all other vehicles in the roundabout.
If you haven't entered the roundabout, pull to the right side of the road and let the emergency vehicle pass you. If you are in the roundabout, continue at a slow speed and exit normally. Then pull to the right side of the road and allow the emergency vehicle to pass you on the left.
