How to Drive a Roundabout in Pennsylvania: Who Yields

informational·how to guide·Published April 3, 2026

Who yields at a roundabout in Pennsylvania?

In Pennsylvania, a driver who enters a roundabout must yield to drivers already in the circle. Slow down at the YIELD sign, stop if safety requires it, look left at the yield line, and enter when there is an adequate gap. Once you are in, you have the right-of-way. Drive counterclockwise, use your right turn signal before your exit, and yield to pedestrians.

Where these roundabout rules come from

This guide uses the Pennsylvania Driver's Manual pages on negotiating intersections and special circumstances and emergencies, the manual's testing and chapter 5 law pages, the 2021 Driver's Manual (PUB 95), and the Vehicle Code sections 75 Pa.C.S. 3321, 3308 and 3323 (as of 2026). The law text says "traffic circles", and PennDOT guidance applies the same yield rule to roundabouts. Confirm the rules with PennDOT Driver and Vehicle Services (pa.gov/dmv) before you drive.

How to enter and exit a roundabout step by step

1
Slow down on the approach
Each entry has a YIELD sign and a yield line painted on the pavement. Slow down and be ready to yield to pedestrians in the crosswalk.
2
Pull up to the yield line and look left
Traffic in the roundabout moves counterclockwise, so drivers already in the circle come from your left. Circulating traffic has the right-of-way.
3
Enter when there is an adequate gap
Wait for an adequate gap in the traffic that comes from your left, then enter.
4
Drive counterclockwise to your exit
After you enter, you have the right-of-way. Keep the center island on your left: every turn into and out of the circle is a right turn.
5
Signal right and watch the crosswalk
Use your right turn signal as you approach your exit. Watch for pedestrians in the crosswalk, be ready to yield, then exit.

Why drivers entering a roundabout must yield

The usual Pennsylvania rule at an intersection is that the driver on the left yields to the driver on the right. The Vehicle Code (75 Pa.C.S. 3321) sets that rule aside in traffic circles: traffic in the circle has the right-of-way. At a roundabout, the car on your left is already in the circle, so it goes first. Order of arrival does not decide either; that idea belongs to the four-way stop rules. At the YIELD sign, yield to any vehicle in the circle or close enough to be a hazard. Test yourself with the free practice question on entering a roundabout.

Which lane to use in a multi-lane roundabout

The yield rule is the same with one lane or two: you yield to the drivers already in the roundabout. For the lane, use the general rule for any intersection. As you approach, look for signs and pavement markings that show which movements each lane allows, and get into the correct lane well in advance. Most roundabouts also have a destination sign on the approach that shows where each exit road goes, so read it before you reach the yield line. The negotiating intersections page linked above has a video on single-lane and multi-lane roundabouts.

What to do when an emergency vehicle comes

You are still on the approach and an emergency vehicle is coming

Do not enter the roundabout. Pull to the side instead.

You are already in the roundabout

Exit the roundabout at once and pull to the side. Never stop in the roundabout.

The emergency vehicle has passed you

Start driving again and keep at least 500 feet away from it.

Pedestrians, bicycles and large trucks at a roundabout

Pedestrians, bicycles and large trucks at a roundabout
Road user	What you do
Pedestrians	Yield to them when you enter and when you exit. They cross each leg at the crosswalks and on the splitter islands. Always yield to a blind pedestrian with a white cane or a guide dog.
Bicyclists	A bicyclist may ride as a vehicle or cross as a pedestrian. A bicyclist who rides as a vehicle follows the same rules as you. Never overtake that bicyclist in the roundabout.
Large trucks	Trucks make wide turns and can use space from other lanes. Do not pass a turning truck until the turn is complete. Do not keep driving alongside a truck: you are in its blind spot.

Staying safe near bicycles and trucks

Slow down to a safe speed when you approach a bicycle. When you pass a bicyclist on other roads, leave at least 4 feet between your car and the bicycle. These truck tips apply on every Pennsylvania road, roundabouts included. A turning truck can look as if it goes straight or turns left when it is making a right turn, so stay put and give it plenty of room. Trucks need longer distances to stop. When you follow a truck or bus and cannot see its side mirrors, its driver cannot see you.

Common mistakes at roundabouts

The most frequent cause of crashes at roundabouts is drivers who fail to yield before they enter. If you drive past a yield sign and hit a vehicle in the intersection, the law treats the crash as prima facie evidence (evidence that stands unless it is disproved) that you failed to yield. The opposite mistake is to insist on the right-of-way once you are in the circle. The law does not give anyone the right-of-way; it only says who must yield. If another driver fails to yield, you must still stop or yield as needed to avoid a crash.

Key takeaways

A driver who enters a Pennsylvania roundabout yields to drivers already in the circle. Once you are in, you have the right-of-way.
Slow down, look left, enter at an adequate gap and drive counterclockwise around the center island.
Use your right turn signal before your exit, and yield to pedestrians when you enter and when you exit.
For an emergency vehicle, do not enter. If you are inside, exit and pull to the side. Never stop in the roundabout.

Roundabout questions in Pennsylvania

Is a roundabout the same as a traffic circle in Pennsylvania?

No. Roundabouts have a special design and special rules, such as a YIELD sign and a yield line at each entry. They are replacing large, old-fashioned, high-speed traffic circles, and many communities build them instead of intersections with traffic signals, mainly for their safety and operational benefits. The Vehicle Code uses the words "traffic circles", and PennDOT applies the same rule to both: entering drivers yield to traffic already in the circle.

Do I have to stop at a roundabout in Pennsylvania?

Not always. A roundabout entry has a YIELD sign, not a stop sign. Slow down to a speed that is reasonable for the conditions, and stop when safety requires it: before the crosswalk when a pedestrian is in it, or at the yield line when a car in the circle is close. Try the free question on yield signs and stopping.

Can I pass a bicycle inside a roundabout?

No. If a bicyclist rides in the roundabout as a vehicle, you must never overtake the rider there. Slow down to a safe speed near the rider. Some bicyclists cross as pedestrians instead, so check the crosswalks for riders when you enter and when you exit.

Do I use a turn signal in a roundabout?

Yes. As you approach your exit, use your right turn signal. Every turn into and out of a roundabout is a right turn, because traffic moves counterclockwise around the center island. After you signal, watch for pedestrians in the crosswalk at your exit and be ready to yield to them.

How do I study roundabouts for the Pennsylvania permit test?

Learn the roundabout steps in the Pennsylvania Driver's Manual. The 2021 manual (PUB 95) has a review question on roundabouts: the correct answer is that entering drivers must yield to drivers in the roundabout or traffic circle, not that the first to arrive goes first. The knowledge test has 18 multiple-choice questions, and you need 15 correct to pass. See how the permit test works.
