Right-of-Way Rules: Who Has to Yield and When

Most of us learn these rules once for the permit test, then guess. Below are the most common situations, most with a scene you can play. Pick who goes first, then watch the cars drive.

What does right-of-way mean?

It means who should go first when two road users want the same space. Here's the odd part: the law doesn't really give anyone the right-of-way. Manuals in states like Connecticut, Iowa and Missouri say the law only tells you who must yield.

So having your turn doesn't mean you can just go. If another driver doesn't yield, let them go. You still have to do everything you can to avoid a crash.

Right-of-way is given, not taken.

Who has the right of way at a 4-way stop?

The car that stopped first goes first. If two cars on different roads stop at the same time, the car on the left lets the car on the right go. Ties, left turns and three-car standoffs each have their own answer, so we gave them a full guide: 4-way stop rules.

Who has the right of way at a two-way stop or yield sign?

The traffic without the sign. At a two-way stop, only one road has stop signs. Stop, then wait for cross traffic, because it won't be stopping. At a yield sign, slow down, and stop if you need to, so you don't get in the way of cars on the other road.

Who has the right of way at an intersection with no signs?

Some intersections have no stop signs or lights. These are called uncontrolled intersections. Slow down and be ready to stop. The car that gets there first goes first. If you arrive at the same time, give way to the car on your right.

Some manuals, like those in Texas and Massachusetts, put it more simply: yield to any car entering or coming from your right. So don't race a car on your right, even if you think you got there first.

And if the car on your left should wait for you, make sure it's actually slowing down. That's Texas's advice: you may legally have the right-of-way, but be sure the other driver yields before you go.

Who has the right of way at a T-intersection?

With no signs or signals, the road that keeps going wins. If your road ends at the T, you wait for traffic on the through road. California says this about T-intersections with no signs, and Texas tells drivers on the road that ends to stop and yield.

At a T, the road that ends gives way.

Who has the right of way when turning left?

Oncoming traffic, even on a green light. A plain green light lets you turn left, but only once it's clear. Wait for cars going straight or turning right. If you have any doubt about the gap, wait. New York's manual says the same, and adds that this applies when you're turning into a driveway or parking lot too.

Turning left? Let oncoming traffic go first.

Who has the right of way in a roundabout?

Cars already in the roundabout go first. Slow down, let anyone in the crosswalk cross, wait for a big enough gap, then enter to the right and go counterclockwise. Don't stop or pass once you're in. If you miss your exit, go around again.

Entering? Let the cars already in it go first.

Who goes first when you pull out of a driveway or merge?

You wait, in both cases. Coming out of a driveway, parking lot or private road, stop and let traffic on the road and people walking go first.

Merging onto a highway works much the same way. Use the ramp to get up to speed and look for an opening, but traffic already in the lane goes first. California puts it simply: when entering traffic, yield to the traffic already in the lanes.

Do pedestrians always have the right of way?

Drive as if they do. California's handbook says it flat out: pedestrians always have the right-of-way. New York says drivers must yield to people using marked or unmarked crosswalks, and must take care to avoid hitting people walking or riding bikes. So there doesn't have to be paint on the road.

This matters most when you're turning, even on a green light. Check the crosswalk you're turning into before you go.

What do you do for an ambulance, police car or fire truck?

When one is coming with its lights or siren on, pull to the right edge of the road and stop until it passes. On a one-way road, Minnesota says to pull to the nearest side. In an intersection when you see it? Don't stop there. California tells you to keep going through the intersection, then move right as soon as it's safe and stop.

If you can't pull over, Texas says to slow down and leave a clear path. New York's manual warns that emergency drivers can legally pass red lights and go the wrong way on one-way streets, so keep an eye on where they're going.

When do you have to stop for a school bus?

When a school bus has its red lights flashing, you stop, whether you're behind it or, on a two-lane road, coming toward it. Stay stopped until the lights go off, and watch for kids after you start moving. Yellow lights usually mean the bus is about to stop, so slow down and get ready.

On wider roads or roads with a median, traffic going the other way may not have to stop. It depends on your state. See where states differ below.

Who has the right of way at a railroad crossing?

The train, every time. As Texas's handbook says, trains do not and cannot stop at crossings. If a train is coming, stop and wait for it to pass. Illinois tells drivers to stop 15 to 50 feet from the tracks. Only start across when you know you can get all the way over.

Do you have to yield to a funeral procession?

In many states, yes. Illinois says drivers must yield to every vehicle in the procession and shouldn't drive between them. Florida says that once the lead vehicle enters an intersection, the rest may follow it through, whatever the signals say. Look for a line of cars with their headlights or hazard lights on, and don't cut in.

Where right-of-way rules differ by state

The basics above are close to the same in most states. Some details change, and those are the ones to check in your state's driver manual.

School buses on divided and multi-lane roads. This is the big one. Traffic behind the bus stops in all of these states. Traffic going the other way is where they differ:

• New York: stop even if the bus is on the opposite side of a divided highway.
• Pennsylvania and Michigan: you don't have to stop if a barrier or median separates you from the bus. Pennsylvania says to slow down and keep going with caution.
• California: you don't have to stop if the bus is on the other side of a divided road or a road with two or more lanes each way.
• Illinois: you don't have to stop if you're both on a four-lane road and the bus is going the other way.
• Utah: on a four-lane road with no median, both directions stop. On a divided road of four or more lanes with a median, or a road of five or more lanes with a center turn lane, traffic going the other way doesn't have to stop.
• Texas: stop from either direction. The handbook names two exceptions: a bus on a different road, or a bus in a loading zone on a controlled-access highway where people can't cross.

Bigger roads. Some states have extra tie-breakers. In Texas, a driver on a one- or two-lane road yields to traffic on a divided road or one with three or more lanes, and a driver on an unpaved road yields to traffic on a paved road.

Older traffic circles. Roundabouts have a clear rule, but New Jersey says there are no set rules for its traffic circles. Usually the circle's long-standing traffic pattern decides who goes first, so read the signs and take it slow.

Move-over laws. Separate from pulling over for a moving ambulance, states also tell you what to do when you pass one stopped on the side of the road, and the details differ. Texas and New York both explain theirs in their manuals.

Common questions

What is the golden rule of right-of-way?

There's no right-of-way rule by that name, but the closest thing is in the Texas and Tennessee manuals: right-of-way is something given, not taken. If going first could cause a crash, don't go.

Who is at fault in an uncontrolled intersection?

It depends on what happened, and police, insurers and courts decide that, not a driving guide. The rules above tell you who was supposed to yield. After a real crash, talk to your insurer or a lawyer in your state.

Does the car on the right always go first?

No. At a 4-way stop, it's only the tie-breaker when two cars stop at the same time. If the car on your left stopped first, it goes first. At an intersection with no signs, play it safe and let a car coming from your right go.

Who has the right of way at a flashing red light?

Treat it like a stop sign: stop, yield, and go when it's safe. New York and Pennsylvania both say it means the same as a stop sign.

What if another driver doesn't yield to me?

Let them go. Texas's handbook says it plainly: if a driver doesn't follow these rules, give them the right-of-way.
