chapter 4 — rules of the road Roundabouts  driving tip 47 When you leave the roundabout, be prepared to yield to  pedestrians who may be in the crosswalk where you are exiting. If you want to turn left, make sure you are in the left lane. If you want to turn right, use the right lane. If you want to go straight, you may use either the left or right lane.  Roundabouts are usually larger than traffic circles.  Some roundabouts have more than one lane. Lane use signs  and markings may be displayed at the approaches to show  where you can go in each lane when you are in the roundabout.  Make sure you know where you want to go — and are in the  proper lane to get there — before you enter a roundabout.  Roundabouts often have a truck apron around the central island  to help large vehicles get through the roundabout.  When you use a roundabout:  Emergency vehicles  displaying flashing  lights and sirens always  have the right-of-way. If  an emergency vehicle  is approaching, avoid  blocking a traffic circle or  roundabout. Stop for the  emergency vehicle before  entering, or exit the traffic  circle or roundabout and  then stop to allow the  emergency vehicle to pass.  • Slow down as you approach the roundabout.  • Yield to pedestrians who may be crossing or about to cross in  the crosswalk located in advance of the roundabout.  • Yield to any traffic already in the roundabout.  • Go around the roundabout in a counter‑clockwise direction.  Do not change lanes in a roundabout.  • Don’t ride alongside large vehicles such as trucks and buses  in roundabouts. They may need more than their lane to go  through the roundabout.  • If you entered the roundabout in the left lane, stay in that  lane. You may either go straight or turn left from that lane.  • Signal “right” before you exit. • Know where you want to go before you enter a roundabout,  and enter the correct lane. Lane use signs or road markings  will show you which lane you need to use.
