Chapter 4 — Your Driving 57 How You Travel Through  A Roundabout Single-Lane Roundabout Multi-Lane Roundabout A roundabout is easy to  travel through once you  understand how it works.  As you approach it, you’ll  see a yellow roundabout  ahead sign, indicating you  should slow down. Drivers  yield to any vehicles or  bicyclists already in the  roundabout. Everyone using the roundabout moves in a counterclockwise  direction, and those already in it do not yield to approaching vehicles. Drivers  should use turn signals when exiting and yield to pedestrians using the  crosswalk at the roundabout. Once inside the roundabout, simply exit at the desired street. You go: Remember to give larger trucks and buses extra room as they may need to  straddle the lane. Big trucks should use the concrete island — called the truck  apron — to help drivers maneuver around the roundabout. Pedestrians should use marked crosswalks along the outside of the roundabout,  and not walk through the middle of it. Bicyclists should pick the appropriate lane before entering a multi-lane  roundabout and stay in the middle of their chosen lane. Do not ride along the shoulder of the roundabout. Drivers should not pass a bicyclist while inside  the roundabout. Never enter a roundabout while an emergency vehicle using flashing lights and  sirens is passing through. If drivers are already in the roundabout, exit first,  then pull over to let the emergency vehicle pass. Tips & Reminders • As you approach, observe signs and pavement markings to choose the  appropriate lane before entering the roundabout. • Typically you will be in the right lane to exit right out of the roundabout. • You stay in the left lane to go straight through the roundabout or make a left  turn or U-turn. • Do not change lanes while in the roundabout • Full circle to make a U-turn • Three-quarters around before exiting to the right, instead of making a  traditional left turn • Halfway around to continue straight • A quarter of the way around to turn right at the next street
