What is the purpose of a roundabout and how do you navigate it safely?

• A. To regulate fast, continuous flow; enter at speed and hurry through.
• B. To regulate slow, continuous flow; yield to traffic inside the circle, stay to the right, and signal when exiting.
• C. To create opportunities for pedestrians to cross without vehicles changing speed.
• D. To serve as a decorative roadway feature with no traffic rules.

Answer: (B)

Roundabouts are designed to slow traffic and keep it moving smoothly by creating a circular path where you yield to vehicles already in the circle and then proceed once there’s a safe gap. The goal is to create a steady, low-speed flow rather than stopping and starting, which reduces crashes and confusion at intersections.

To navigate safely: approach with caution and look for pedestrians at crosswalks; yield to traffic inside the circle and to those crossing at entrances or exits. When there’s a safe gap, enter the roundabout by moving to the right and circulating at a careful, steady pace. Stay to the right side while inside the circle and do not stop inside unless absolutely necessary. Signal your intention to exit as you pass the exit you plan to take, then merge smoothly onto the road after you’ve left the circle. If you miss your intended exit, continue around to the next one. Large vehicles may require more space or multiple lanes, so be mindful of their movement as well.
