When using a roundabout or rotary island, drivers should:
- Yield to entering traffic.
- Yield to traffic already in the roundabout. ✓
- Drive in a clockwise direction.
- Stop within the rotary island.
Answer: B. Yield to traffic already in the roundabout.
When you enter a roundabout, you must yield to traffic already circulating in it.
Why this is the answer
The handbook describes a roundabout as a circular intersection with no signal where traffic moves one way in a counter-clockwise direction. It says plainly that drivers entering must yield to vehicles already in the roundabout, and that if there is no traffic you may enter without yielding. That makes giving way to circulating traffic the rule for entering, which is what the correct choice describes.
Why the other answers are wrong
- A. Yield to entering traffic. — This reverses the rule: it is the entering driver who yields, not the traffic already circulating.
- C. Drive in a clockwise direction. — The handbook says roundabout traffic travels counter-clockwise, so clockwise is the wrong direction.
- D. Stop within the rotary island. — The handbook specifically says not to stop in a roundabout, so stopping inside it is not permitted.
Remember it
Think of the circle as having the right of way: wait at the entry line, then join when there is a gap.
