Roundabouts

A roundabout replaces the stop-and-go of a normal intersection with one continuous, counterclockwise flow — and one rule: yield before you enter.

Roundabouts unsettle a lot of new drivers — no light to tell you when to go, cars flowing past continuously. But a roundabout actually has fewer rules to remember than a signalized intersection: yield before you enter, and everything else follows from there.

💡
The big idea: A roundabout is yield-controlled, not stop-controlled: vehicles already circulating inside always have the right-of-way over vehicles entering, traffic moves counterclockwise around the center island, and you signal your exit the way you would any turn.
🎯 By the end, you'll be able to
  • Yield correctly on entry to a roundabout instead of stopping unnecessarily
  • Travel counterclockwise around the central island and choose the correct lane for your exit
  • Signal your exit and avoid stopping inside the circle without cause
  • Yield to pedestrians in the crosswalks at each entrance and exit

A yield-controlled circle, not a stop-controlled intersection

Unlike a 4-way stop, you generally do not need to come to a full stop to enter a roundabout — you only need to yield to traffic already circulating. If the circle is clear, you can enter without stopping at all; if it isn't, you slow or stop at the entry line and wait for a gap.

The entering car (highlighted) yields to the car already circulating — inside the circle always has priority over entering it.
🔑 Three rules cover almost every roundabout
  1. Yield on entry. Traffic already inside the circle always has the right-of-way over traffic entering — look left (the direction traffic is coming from) before you enter.
  2. Travel counterclockwise. All roundabouts in the U.S. circulate counterclockwise around the central island — never enter against that flow.
  3. Signal your exit. Use your right turn signal just before the exit you're taking, the same as leaving a highway.

Multi-lane roundabouts: pick your lane before you enter

Larger roundabouts have two or more circulating lanes. As a rough guide: use the right lane if you're exiting soon (the first exit or going right), and the left lane if you're going straight across or taking a later exit. Choose your lane before entering — signs and pavement arrows at the entry point will confirm which lane serves which exits — and stay in it through the circle rather than changing lanes mid-roundabout.

⚠️ Don't stop inside the circle
Once you're circulating, keep moving — stopping inside a roundabout (outside of yielding to a pedestrian or an emergency vehicle) creates a hazard for everyone behind you. And never enter or travel in the wrong direction around the island, even to make a shortcut turn.

Pedestrians still come first

Every entrance and exit of a roundabout typically has its own crosswalk, just outside the circle. Pedestrians there have the same right-of-way they'd have at any other crosswalk — yield to them before you enter or as you exit, even if circulating traffic is clear.

Check your understanding

1. You approach a roundabout and the circle is completely clear of traffic. What should you do?
A roundabout is yield-controlled, not stop-controlled. If the circle is clear, you can enter without a full stop — you only need to stop if there's traffic to yield to.
2. Which direction does traffic travel around a U.S. roundabout's central island?
All U.S. roundabouts circulate counterclockwise around the central island — entering or traveling clockwise would put you head-on into oncoming traffic.
3. You're already circulating in a roundabout when another car is waiting to enter. Who has the right-of-way?
Vehicles already circulating inside a roundabout always have the right-of-way over vehicles waiting to enter.
4. As you're about to take your exit from a roundabout, you should:
Signal before your exit just as you would for any turn — it tells drivers waiting to enter that you're about to leave the circle.
✅ Key takeaways
  • A roundabout is yield-controlled — enter without stopping if the circle is clear, yield if it isn't.
  • Traffic already circulating always has the right-of-way over traffic entering.
  • U.S. roundabouts always travel counterclockwise around the central island.
  • Signal your exit, avoid stopping inside the circle, and yield to pedestrians at every crosswalk.
➡️ Roundabouts settle who enters the intersection. The next lesson covers what happens once you're inside one, making a turn: left turns, and the T-intersections where one road always has priority.

Frequently asked questions

Do you have to stop at every roundabout?
No. A roundabout is yield-controlled, not stop-controlled — you only need to slow or stop if there's circulating traffic to yield to. If it's clear, you may enter without stopping.
Which direction do cars go around a roundabout?
Counterclockwise around the central island, in every U.S. roundabout — the same direction you'd expect from any right-hand-drive traffic pattern.
What if I miss my exit in a roundabout?
Stay in the circle and simply continue around to take the same exit again — never stop or reverse inside a roundabout to correct a missed exit.
