How Four-Way Stops Work in South Carolina

What a four-way stop is and how to proceed through one

A four-way stop is an intersection where all four directions of traffic face a stop sign. When you arrive at one, you must come to a complete stop—your vehicle's wheels must stop moving entirely. After stopping, you yield the right of way to any vehicle that arrived at the intersection before you did. If two vehicles arrive at the same time, the vehicle on your left yields to you, and you yield to any vehicle on your right.

The key rule is this: first to arrive, first to go. If you and another driver arrive simultaneously and neither is turning left across the other's path, the driver on the right has the right of way. If you're turning left and another vehicle is going straight, the straight-going vehicle goes first, even if you arrived at the same moment.

Many drivers hesitate or wave other cars through at four-way stops, but this creates confusion and can cause accidents. Follow the arrival order and directional rules instead. If you're unsure who arrived first, make eye contact with the other driver and let them proceed—but do this through clear gestures, not by rolling down your window or honking.

Key Takeaways

• Come to a complete stop at a four-way stop, not a rolling stop or a slow creep.
• The vehicle that arrived first has the right of way; if you arrived second, wait for them to clear the intersection.
• When two vehicles arrive simultaneously, the one on your right goes first; if you're turning left and they're going straight, they go first.
• Waving other drivers through creates confusion and increases accident risk—stick to the legal right-of-way rules instead.
• South Carolina law requires you to yield to pedestrians and bicyclists in the crosswalk, even at a four-way stop.

What happens when arrival times are unclear

If you cannot tell who arrived at the intersection first, assume the other vehicle arrived before you and let them proceed. This is the safest approach and keeps traffic moving. Most drivers will recognize your caution and move through the intersection promptly.

If multiple vehicles arrive at exactly the same moment—a rare but possible scenario—the vehicle furthest to the right has the right of way. This rule prevents gridlock and gives drivers a clear hierarchy to follow. For example, if you're facing north and another car is facing east, the eastbound car (on your right) proceeds first.

Turning left at a four-way stop

Turning left at a four-way stop requires extra caution because you must cross the path of oncoming traffic. Even if you arrived at the intersection first, you must yield to any vehicle coming straight toward you. This means if you arrived first but want to turn left, and another car arrived second but is going straight, that straight-going vehicle goes first.

After the oncoming traffic clears, you may complete your left turn. If multiple vehicles are turning left from opposite directions, you may turn simultaneously as long as neither vehicle crosses the other's path. Use your turn signal well before the intersection so other drivers know your intention.

Pedestrians and bicyclists at four-way stops

South Carolina law requires drivers to yield to pedestrians in a marked or unmarked crosswalk, regardless of traffic control devices. At a four-way stop, this means you must watch for people crossing before you proceed, even if you have the right of way based on arrival order. Pedestrians have the right to cross when traffic has stopped.

Bicyclists must follow the same rules as cars at a four-way stop—they must stop and yield according to arrival time and direction. However, some riders may not stop completely or may be difficult to see. Before proceeding through a four-way stop, scan the entire intersection for pedestrians, cyclists, and motorcycles, especially in urban areas or near schools and parks.

Common mistakes that cause accidents

The most dangerous mistake is waving another driver through. When you wave, the other driver may think you're yielding to them, but a third vehicle might also be proceeding, or a pedestrian might step into the intersection. This miscommunication causes T-bone collisions and pedestrian strikes. Let the rules of the road do the communicating instead.

Rolling stops—slowing down without fully stopping—are illegal and unsafe. Your vehicle must stop completely. Many drivers in South Carolina treat four-way stops as yield signs, which leads to crashes. Come to a full stop every time, even if the intersection looks clear.

Failing to look both ways and behind you is another common error. Before proceeding, check left, right, and behind for vehicles that may be running the stop sign or turning from an unexpected direction. This extra moment of observation can prevent a serious collision.

Four-way stops versus traffic lights and yield signs

A four-way stop is different from a traffic light, where a green light gives you the right of way without needing to check arrival order. At a traffic light, you proceed when the light turns green (after checking for red-light runners). At a four-way stop, you must judge arrival time yourself.

A four-way stop is also different from a two-way stop, where only two directions face stop signs and the other two directions have the right of way. At a two-way stop, vehicles on the through street go first. At a four-way stop, all four directions are equal, so arrival order determines who proceeds.

Yield signs mean you must slow or stop if necessary to let other traffic pass, but you don't have to stop if the intersection is clear. Stop signs require a complete stop regardless of whether other traffic is present. Four-way stops are stop signs, so treat them as mandatory stops every time.

Frequently Asked Questions

Do I have to stop at a four-way stop if no other cars are around?

Yes. South Carolina law requires a complete stop at every stop sign, whether or not other traffic is present. Police can cite you for a rolling stop or failure to stop even in an empty intersection. The rule exists for consistency and safety—if you stop only when you see other cars, you may miss a vehicle approaching from a blind spot.

What if another driver doesn't stop and enters the intersection first?

Let them go. Your right of way does not protect you in a collision. Even if you arrived first, if another vehicle is already in the intersection, do not proceed. Avoid the crash, then report the incident to local police if you have their license plate and a description of the vehicle.

Can I turn right on red at a four-way stop?

No. A four-way stop is not a traffic light. You must follow the same arrival-order and directional rules as any other vehicle. You cannot turn right on red unless a sign explicitly permits it, which is rare at four-way stops. Treat it as a stop sign that applies to all directions equally.

Who goes first if three cars arrive at the same time?

The vehicle furthest to the right has the right of way. If you're facing north, a car facing east (on your right) goes first, then the car facing south, then the car facing west (on your left). If you're unsure of the exact order, wait for at least one vehicle to clear the intersection before proceeding.

Do I need to make eye contact with other drivers at a four-way stop?

Eye contact can help confirm that another driver sees you and understands the right-of-way situation, but it is not required. Rely on the legal rules—arrival order and direction—rather than assuming eye contact means agreement. If you're uncertain, wait and let the other vehicle proceed first.
