Roundabouts — Oregon Permit Test

In a roundabout traffic moves in one direction, counterclockwise, around the center island, and before entering you must yield to traffic inside the roundabout as well as traffic exiting it.

Yielding to the traffic already circulating is what keeps a roundabout moving; entering into a gap that is about to close is what stops it.

Before you enter the roundabout, you must yield to traffic inside as well as exiting the roundabout.

Approaching a roundabout, slow down, look for signs to find your exit, watch for people riding bicycles who will either merge into traffic or use the sidewalk, and stop for pedestrians using the crosswalk in your lane.

The crosswalk comes before the yield line, so the first thing to stop for is on foot rather than in the circle.

When approaching the crosswalk, stop for pedestrians using the crosswalk in your lane.

Inside a roundabout, allow people riding bicycles who have merged into traffic the full travel lane, and do not pass a person riding a bicycle within the roundabout.

A cyclist taking the lane is doing the right thing, and squeezing past them inside the circle leaves nowhere for either of you to go.

Allow people riding bicycles that have merged into traffic the full travel lane. Do not pass a person riding a bicycle within the roundabout.

Indicate your plan to exit a roundabout using your right turn signal, watching for pedestrians in the crosswalk and being prepared to stop.

The exit signal is what tells a driver waiting to enter that the gap is real, and the crosswalk on the way out is the last thing drivers check.

Exit: Indicate your plan to exit using your right turn signal.

In a multi-lane roundabout, enter using the appropriate lane for your exit and maintain your lane position until you exit, avoiding lane changes inside the roundabout where possible.

The lane is chosen before the yield line because there is no room to correct once you are circulating beside another vehicle.

Enter the roundabout using the appropriate lane for your exit. Maintain your lane position until you exit.

It is illegal to pass or drive beside a truck within a roundabout, because trucks may need to straddle both lanes.

A truck taking both lanes is using the roundabout correctly, and the space beside it closes as the trailer tracks inside the turn.

Trucks may need to straddle both lanes. It is illegal to pass or drive beside a truck within the roundabout.

Do not enter a roundabout when emergency vehicles are approaching — pull over to the right; never stop inside a roundabout, but move through and exit, then pull over to the right shoulder to let them pass.

Stopping inside blocks the whole circle for the emergency vehicle, so the rule is the opposite of pulling over everywhere else.

Never stop while inside the roundabout. Instead, move through and exit the roundabout. Once you exit, pull over to the right shoulder and allow emergency vehicles to pass.

Who must a driver yield to before entering a roundabout?

Traffic inside the roundabout and traffic exiting it. Yielding to the traffic already circulating is what keeps a roundabout moving; entering into a gap that is about to close is what stops it. 2026-2027 Oregon Driver Manual, p.43: “Before you enter the roundabout, you must yield to traffic inside as well as exiting the roundabout.”
