One-lane traffic circle / roundabout An example of a single-lane circular intersection. Entering circular intersections: Drivers entering a one-lane circular intersection must yield to drivers already in the circle. Once in the circle, drivers must activate the right signal when preparing to exit. Exiting circular intersections: Always wait to activate your right turn signal after passing the exit that is before your intended exit. This tells other drivers that you intend to leave the circle at the next exit. When you intend to exit at the first available exit:
• Use your right signal as you approach. Leave it on until you have exited the circle.
• As you approach, scan for pedestrians and cyclists at the crosswalks at the entrance and exits of the circle.Text extracted from the PDF for reference and may contain layout artefacts. The official PDF is authoritative.
