Multi-lane Roundabouts

How to drive multi-lane roundabouts

• Slow down to 15 to 20 mph when approaching the roundabout.
• Choose the appropriate lane. Just like a standard intersection, you must choose the proper lane for your destination based on lane markings prior to entering the roundabout intersection. Do not change lanes in the roundabout.
• Yield to pedestrians in crosswalks . . .It's the law!
• Yield to traffic that is already in the circle approaching from the left. Never merge. Wait for a gap in traffic, then carefully proceed into the roundabout.
• Proceed based on the lane you have chosen and exit appropriately. Do not change lanes in the roundabout.

• For right turns, travel in the right lane and exit based on the exit lane markings.
• For left turns, travel in the left lane.
• For continuing forward, remain in the same lane you entered.

By understanding what a modern roundabout is and how it works, motorists, bicyclists and pedestrians can travel through intersections easier and more safely.
