When using a roundabout, drivers should:
- Stop in the middle of the roundabout.
- Yield to traffic already in the roundabout. ✓
- Yield to entering traffic.
Answer: B. Yield to traffic already in the roundabout.
When you use a roundabout, you yield to traffic that is already circulating in it.
Why this is the answer
The handbook's step-by-step directions say to slow down on approach and then yield to all traffic already in the roundabout, entering only when there is a big enough gap to merge safely. Traffic inside has the right of way, so entering drivers wait for that gap. The same passage also tells you not to stop once you are in the roundabout, which is why halting in the middle is not part of using one.
Why the other answers are wrong
- A. Stop in the middle of the roundabout. — The handbook says not to stop while traveling in a roundabout, so coming to a stop in the middle goes against the rule.
- C. Yield to entering traffic. — It works the other way around: drivers entering the roundabout yield to those already in it, not the reverse.
Remember it
Think of the circle as the other drivers' lane: you wait for a gap before you join it.
