You're approaching an Oregon roundabout. What's the entry rule?
-
A.
Stop at the entry line, then merge into traffic.
-
B.
Yield to traffic inside and exiting the roundabout, then merge during a gap. Correct
-
C.
Accelerate to merge with circulating traffic at speed.
-
D.
Traffic entering the roundabout has the right of way over circulating traffic.
The answer is "Yield to traffic inside and exiting the roundabout, then merge during a gap."
Before entering a roundabout, you must yield to traffic already inside the circle as well as to traffic exiting the roundabout. Wait for a gap and merge. Roundabouts are not stop-controlled at entry; you only stop if needed to yield. Once inside, do not stop unless you must, and follow the counterclockwise flow to your exit.
The traps in the wrong answers
A. Stop at the entry line, then merge into traffic.
Roundabouts are yield-controlled at entry, not stop-controlled. You only stop if needed to yield to a gap. Misreading: Treats the roundabout entry as stop-controlled when the manual says you must yield, stopping only if necessary.
C. Accelerate to merge with circulating traffic at speed.
You slow down on approach, look, and yield; you do not accelerate to force a merge. Misreading: Confuses freeway on-ramp merging with roundabout entry; the manual says slow down and yield, not accelerate.
D. Traffic entering the roundabout has the right of way over circulating traffic.
The opposite is true: traffic already inside the roundabout has priority over entering vehicles. Misreading: Inverts the yield rule; the manual requires entering drivers to yield to traffic already inside the circle.
