Before entering a roundabout, you must slow down and yield to:
- Vehicles in the roundabout.
- Bicyclists in the roundabout.
- Pedestrians in the roundabout.
- All of the above. ✓
Answer: D. All of the above.
You must slow down and yield to all of the above: vehicles in the roundabout, bicyclists, and pedestrians.
Why this is the answer
The handbook's roundabout steps say to slow down as you approach the intersection and yield to traffic already in the circle before entering when there is an acceptable gap. It also tells you to watch for bicyclists and pedestrians using the crosswalks on the roundabout approaches and exits. So the yielding duty is not limited to cars only — everyone already in or crossing at the roundabout has your respect before you enter.
Why the other answers are wrong
- A. Vehicles in the roundabout. — Yielding to vehicles in the circle is part of the rule, but stopping there leaves out the bicyclists and pedestrians the handbook also tells you to watch for.
- B. Bicyclists in the roundabout. — Bicyclists using the crosswalks are covered by the rule, yet naming only them ignores the traffic already circling and the pedestrians crossing.
- C. Pedestrians in the roundabout. — Pedestrians on the roundabout approaches and exits do have to be yielded to, but the rule also covers vehicles in the circle and bicyclists.
Remember it
Think of the circle as their space first: cars already going around, plus anyone on foot or on a bike at the crosswalks, all get to go before you.
