Roundabouts keep appearing across North Carolina, and with them a new kind of fender bender. The statute that governs them is one sentence long.
Modern roundabouts replaced many four-way stops and signals because they slow traffic and turn deadly broadside crashes into glancing ones. They still produce collisions, and almost all of them come back to one question: who was in the circle first?
Joshua E. Palmer, Attorney at Law represents people injured in North Carolina crashes. This page explains the right-of-way rule, how fault is argued in roundabout collisions, and what to document if you are hit in one.
The rule is N.C. Gen. Stat. § 20-155(d): the driver of any vehicle approaching but not having entered a traffic circle shall yield the right-of-way to a vehicle already within the circle. The statute uses the older term traffic circle, but it applies the same way to modern roundabouts. Yield signs at each entry reinforce it.
Yielding means more than slowing. The entering driver has to wait for a gap that lets them enter without forcing a circulating car to brake or swerve. Pedestrians matter too: where no signal is operating, N.C. Gen. Stat. § 20-173(a) requires drivers to yield to pedestrians in a marked crosswalk or an unmarked crosswalk at an intersection, and roundabout crosswalks sit at the entries and exits.
| Crash | Usually at fault | What the insurer will ask |
|---|---|---|
| Entering car hits a circulating car | Entering driver (§ 20-155(d)) | Was the circulating car speeding or changing lanes? |
| Rear-end at the yield line | Following driver | Did the lead car stop suddenly without reason? |
| Side-swipe between two lanes inside the circle | Driver who left their lane | Which lane each car used to enter and exit |
| Pedestrian struck in a crosswalk | Driver | Was the pedestrian in the crosswalk? |
Multi-lane roundabouts add lane choice. Signs and pavement arrows tell drivers which lane to use for each exit, and the general rule in N.C. Gen. Stat. § 20-146(d) requires a driver to stay within a single lane and not move from it until the movement can be made safely. A driver who exits from the inside lane across a car in the outside lane, or drifts between lanes while circulating, is usually the one who breached that duty.
Signals matter as evidence but not as a legal shortcut. Under N.C. Gen. Stat. § 20-154(a) a driver must signal and make sure a movement is safe, but a violation of that section is not negligence per se, so the insurer will weigh it with everything else.
Yes, and in North Carolina that question can decide the whole claim. Having the right of way does not excuse driving too fast for a roundabout’s tight curve; N.C. Gen. Stat. § 20-141(a) requires a speed that is reasonable and prudent under the conditions. Under contributory negligence, if the circulating driver’s own negligence contributed to the crash, the entering driver’s insurer can refuse to pay at all.
Expect the adjuster to look at video, the damage pattern, and statements for any sign of speed or inattention by the driver with the right of way. If the entering driver pulled out so close that a careful driver could not have avoided the collision, that argument should fail.
Move to safety, call police if anyone is hurt or the damage may reach $1,000, and photograph the entry you and the other driver used, the lane markings, the yield signs, and the damage. Ask nearby homes and businesses about cameras. Then talk with a North Carolina car accident lawyer before giving the other insurer a recorded statement.
