At a North Carolina roundabout, approaching traffic yields to vehicles already circulating. That entry rule is different from trying to apply a general uncontrolled-intersection rule to every circular roadway design.

The statutory right-of-way rule

North Carolina G.S. 20-155(d) says that a driver approaching but not yet in a traffic circle must yield to a vehicle already within it. The same statute contains other right-of-way rules for different situations, including vehicles arriving at an intersection from different highways and left turns. The applicable instruction depends on the roadway and movement involved.

NCDOT describes modern roundabouts as smaller than older traffic circles and gives practical operating guidance for a roundabout. This guide uses the statutory traffic-circle wording and NCDOT’s roundabout guidance without treating every circular design as legally identical.

Approaching and entering a roundabout

NCDOT advises drivers to slow as they approach, look for the roundabout-ahead sign, and yield to vehicles or bicyclists already in the roundabout. Traffic moves counterclockwise. A driver should wait for a suitable gap before entering rather than assume that approaching traffic has priority.

Lane choice matters at multilane roundabouts

At a multilane roundabout, signs and pavement markings at that particular location control the appropriate lane choice. NCDOT advises drivers to select the lane before entering and not change lanes while inside. General lane examples can be useful, but they do not replace the signs and markings at the roundabout being used.

  • Use the right lane when the posted signs and pavement markings direct that movement.
  • Stay in the selected lane while circulating; do not make an unplanned lane change inside the roundabout.
  • Signal when exiting.
  • Give large trucks and buses room because they may need additional space to maneuver.

People walking, bicycling, and emergency vehicles

NCDOT directs drivers to yield to pedestrians using marked crosswalks at a roundabout. It also advises bicyclists at a multilane roundabout to choose a lane before entering and remain in that lane, and advises drivers not to pass a bicyclist inside the roundabout. If an emergency vehicle is approaching with flashing lights and sirens, a driver already in the roundabout should exit first and then pull over when it is safe.

Keep the operating rule separate from a collision conclusion

An entry conflict, circulating-lane conflict, exit conflict, or crosswalk conflict may involve different facts. The operating guidance here does not determine speed, fault, injury cause, insurance coverage, or damages for a particular event. Information about Charlotte car-accident claims involving roundabout collisions is available when a roadway collision requires a fact-specific review.
