At an intersection, the right of way rules come down to a simple default with a lot of exceptions: when two vehicles arrive at about the same time from different roads, the driver on the left yields to the driver on the right. What changes that default is whatever controls the intersection: a stop sign, a signal, a yield, a roundabout, or nothing at all. A vehicle already in the intersection always has priority over one that hasn’t entered yet, no matter which direction it came from.1National Highway Traffic Safety Administration. Right-of-Way Rules
No Signs or Signals
Uncontrolled intersections are common in residential neighborhoods and rural areas. Approach slowly and be ready to stop. If another car arrives at the same moment from your right, let it go first. If you got there clearly first, you can proceed, but don’t assume the other driver knows the rule or has seen you.
At a T-intersection, one road dead-ends into another. The driver on the terminating road yields to traffic on the through road, even if no sign is posted. You’re joining someone else’s road, so you wait for a gap. If a stop or yield sign is posted, follow it; the practical outcome is the same.
Four-Way Stops
At a four-way stop, every approach has a stop sign, usually marked with an “ALL WAY” plaque below it. Priority stacks in this order:
- First to come to a complete stop goes first.
- If two vehicles stop at the same time, the one on the right goes first.
- If two vehicles stop at the same time directly across from each other, the one going straight goes before the one turning left.
When it’s genuinely unclear, yield. NHTSA’s own guidance puts it bluntly: “When in doubt, bail out.”1National Highway Traffic Safety Administration. Right-of-Way Rules
Two-Way Stops and Yield Signs
At a two-way stop, only some approaches have stop signs. If you’re on the road with the sign, stop fully and then yield to all cross-traffic before pulling out. The cross street has no stop sign and no reason to slow down for you. Wait for a safe gap, even if that takes several passes of traffic.
A yield sign is not a stop sign. It asks you to slow down and be ready to stop. If the intersection is clear, you can proceed without stopping. If it isn’t, you must give way to vehicles and pedestrians already in the intersection or close enough to be a hazard, and treat the sign like a stop.
Left Turns at Green Lights
Left turns produce more intersection conflicts than any other maneuver, and the rule applies at both stop signs and green lights: a driver turning left yields to all oncoming traffic going straight or turning right.1National Highway Traffic Safety Administration. Right-of-Way Rules
Protected Turns
A green arrow pointing left gives you a protected turn. Oncoming traffic has a red light, so you can turn without yielding. When the arrow disappears and only a solid green circle remains, the turn becomes unprotected and the yielding rule returns. Some intersections use a flashing yellow arrow for this phase instead of a solid green. The flashing yellow arrow means you may turn, but you must yield to oncoming traffic and pedestrians first.2Federal Highway Administration. MUTCD 2009 Edition Chapter 4D – Traffic Control Signal Features
Unprotected Turns
On a solid green with no arrow, you may pull forward into the intersection and wait for a gap. Keep your wheels pointed straight. If you angle them left and get rear-ended, the impact pushes you into oncoming lanes. Complete the turn when a safe gap opens, or when the light turns yellow and oncoming traffic stops. If you’ve already entered the intersection on a green, you’re legally allowed to finish the turn even after the light changes.
Right Turns on Red
Every state permits right turns on red unless a sign at the intersection says otherwise. The requirements are the same everywhere:
- Come to a full stop at the red light.
- Yield to all pedestrians in the crosswalk and all cross-traffic with the green.
- Proceed only when you can do so without endangering anyone.
Some cities prohibit right on red throughout their jurisdiction unless a sign specifically allows it. New York City is the best-known example. At an unfamiliar intersection, look for a “No Turn on Red” sign before assuming the turn is legal.
Flashing and Dark Signals
A flashing red light means the same thing as a stop sign. Stop fully, yield to anyone already in the intersection, and go when it’s safe. If every direction is flashing red, treat it as a four-way stop.2Federal Highway Administration. MUTCD 2009 Edition Chapter 4D – Traffic Control Signal Features
A flashing yellow light means proceed with caution. You don’t have to stop, but slow down and watch for cross-traffic and pedestrians. The flashing yellow side typically has priority over the flashing red side at the same intersection, so if you’re facing yellow, the cross street is facing red.2Federal Highway Administration. MUTCD 2009 Edition Chapter 4D – Traffic Control Signal Features
When a traffic light is completely dark, most states require you to treat the intersection as an all-way stop. Every approach stops, then follows the standard four-way priority rules. Slow down well before the intersection, because some drivers won’t notice the signal is out until they’re nearly in it.
Roundabouts
Roundabouts reverse the usual logic. Everyone moves in the same circular direction, and the rule is simple: vehicles already in the roundabout have the right of way. Every entry has a yield sign, and drivers entering wait for a gap in circulating traffic before merging.3Federal Highway Administration. Roundabouts – An Informational Guide
Signal your exit with a right turn signal. If you’re taking the first exit, signal right on approach. If you’re going further around, turn the signal on after you pass the exit just before yours. Don’t stop inside the roundabout to let someone in; that defeats the design and creates a collision risk.
Pedestrians at Any Intersection
Drivers must yield to pedestrians in a crosswalk, painted or not. An unmarked crosswalk exists at every intersection where sidewalks or paths meet the road. In practice, any pedestrian crossing at a corner likely has the legal right of way. Fines for failing to yield to a pedestrian range from roughly $25 to several hundred dollars depending on where you are, along with demerit points on your license.
Penalties climb sharply when the pedestrian is visually impaired and using a white cane or guide dog. Many states treat failure to yield to a blind pedestrian as a misdemeanor carrying fines up to $1,000 and up to six months in jail.
Emergency Vehicles and Funeral Processions
When you hear a siren or see flashing emergency lights, pull to the right edge of the road and stop. Stay there until the vehicle passes. This applies regardless of the direction the emergency vehicle is coming from.4National Highway Traffic Safety Administration. Move Over – Its the Law If you’re already in an intersection, clear it first, then pull over. Fines for ignoring an emergency vehicle commonly run several hundred dollars with demerit points added, and if your failure to yield injures or kills emergency personnel, some states escalate the charge to a felony.
Most states give funeral processions some form of right of way. Once the lead vehicle legally enters an intersection, the rest of the procession can follow through even if the signal changes, and other drivers are prohibited from cutting through the line. Procession vehicles typically run headlights on during the day and may carry small flags or placards. Emergency vehicles are usually the only ones allowed to pass through.
What Happens If You Get It Wrong
A failure-to-yield ticket is one of the most common traffic violations. Base fines range from about $25 to several hundred dollars, with court fees and surcharges that push the real cost higher. Expect one to three demerit points on your driving record, which can raise your insurance premiums for years.
The bigger cost shows up after a crash. If you failed to yield and caused the collision, the violation creates a strong presumption of fault in any insurance claim or lawsuit. The other driver’s medical bills, vehicle damage, and lost wages become your financial responsibility. Right of way is the framework courts use to decide who pays.
