What are Roundabout Rules?
Roundabout rules govern how vehicles enter, circle and exit a roundabout safely. The core principle: traffic on the roundabout has priority, so yield when entering and signal clearly before exiting.
Roundabout rules require you to yield to traffic already in the roundabout, stay in the correct lane while circling, and signal your exit. Priority goes to vehicles on the roundabout, not entering.

Step-by-step worked examples
Approaching a roundabout, a car is inside circling. Can you enter?
No, traffic inside the roundabout has priority. Yield and wait for a safe gap. Result: Only enter when the inner lane is clear for your desired exit.
Inside the roundabout, you're taking the third exit. Which lane?
Use the right lane for a third exit (right turn). Stay in that lane and signal before exiting. Result: Safe, predictable exit.
Two lanes in a roundabout. You're exiting left. From which lane?
Exit from the left lane when making a left turn. Signal before you start leaving the roundabout. Result: Clear intent, no collision risk.
