Passing on the right is legal in two situations and only two: when the vehicle ahead is turning left, or when the road is wide enough for two or more lines of traffic moving in your direction. That’s the rule in the Uniform Vehicle Code, which most state traffic laws follow.1National Committee on Uniform Traffic Laws and Ordinances. Uniform Vehicle Code (Millennium Edition 2000) Outside those two situations, overtaking on the right is a moving violation. In a few scenarios, most notably passing a stopped school bus, the penalties are severe enough to cost you your license or your livelihood.
The Two Situations Where It’s Legal
Section 11-304 of the Uniform Vehicle Code allows a right-side pass when the driver ahead is making or about to make a left turn.1National Committee on Uniform Traffic Laws and Ordinances. Uniform Vehicle Code (Millennium Edition 2000) If the car in front has a left turn signal on or has moved into a left-turn lane, you can go around on the right rather than wait for them to clear.
The second situation is a road with unobstructed pavement wide enough for two or more lines of vehicles traveling in your direction.1National Committee on Uniform Traffic Laws and Ordinances. Uniform Vehicle Code (Millennium Edition 2000) On a four-lane highway with two lanes going each way, moving past a slower car in the left lane by using the right lane is normal legal driving. One-way streets with multiple lanes meet the same threshold.
On a standard two-lane road with one lane in each direction, there is no legal right-side pass. The road is not wide enough for two lines of traffic going the same way. Your only option is to pass on the left when the center line and oncoming traffic allow it.
Even When It’s Legal, It Has To Be Safe
The Uniform Vehicle Code attaches a condition to every legal right-side pass: it must be done safely.1National Committee on Uniform Traffic Laws and Ordinances. Uniform Vehicle Code (Millennium Edition 2000) A pass that fits the layout rule can still be cited if conditions make it dangerous.
That puts the judgment on you. The vehicle you’re passing might be stopped for a pedestrian you can’t see. The lane that looked clear might narrow around a delivery truck whose mirror extends into your path. Debris, parked cars, and shrinking shoulders all count against the maneuver even when the road markings are permissive.
Where You Can Never Pass on the Right
You cannot leave the roadway to pass. Driving onto the shoulder, paved or gravel, to get around a car waiting to turn left is a moving violation in nearly every state. Shoulders are for breakdowns and emergencies.
Bike lanes and transit-only lanes are off limits for the same reason. Solid white lines separate them from the regular travel lanes, and crossing those lines to overtake is illegal even where the surface is drivable. HOV and express lanes work the same way. You can only enter or exit at the dashed-line gaps; cutting across a solid line to use an express lane as a passing lane adds a second violation on top of the illegal pass.
Stopped School Buses
Every state, the District of Columbia, and U.S. territories prohibit passing a school bus with its red lights flashing and stop arm extended.2National Highway Traffic Safety Administration. Reducing the Illegal Passing of School Buses The right side is where children board and exit, and the area within roughly 10 feet of the bus is a danger zone where the driver may not be able to see a child.3Traffic Safety Marketing. School Bus Safety Week Fact Sheet
Penalties vary by state but are consistently steep. First-offense fines commonly run from $250 to $1,000, with three to six license points added in many states. Repeat offenders face license suspension, mandatory community service, and in some states felony charges when the violation causes injury or death. Stop-arm cameras now catch violators automatically in many jurisdictions.
States split on whether drivers in the opposite direction have to stop on a divided highway. In some states a physical median exempts oncoming traffic; in others, every direction must stop regardless of the road layout. Check your state’s rule, because the fine for assuming wrong is not small.
Passing Large Trucks on the Right
On a multi-lane road, passing a large truck on the right is legal. The Federal Motor Carrier Safety Administration still advises against it.4Federal Motor Carrier Safety Administration. Tips for Passenger Vehicle Drivers A truck’s right-side blind spot extends roughly 20 to 30 feet from the cab, far larger than the one on the left. If you can’t see the driver’s face in their side mirror, they don’t know you’re there.
The worst version of this is the right-turn squeeze. Semi-trucks need 50 to 60 feet of space to complete a turn and often swing left before turning right. A driver who reads that leftward swing as a left turn and tries to slip past on the right ends up directly in the truck’s path. When a large truck signals any turn at an intersection, hang back.
Stopped Vehicles on the Shoulder
All 50 states have move-over laws. When you approach a stationary emergency vehicle with flashing lights on the side of the road, you have to change out of the lane next to it, or slow to a reasonable speed if you can’t change lanes safely.5National Highway Traffic Safety Administration. Move Over: It’s the Law Blowing past a stopped police car, ambulance, or fire truck on the right at full speed when a left lane was open is a citable offense.
Nineteen states and Washington, D.C. apply the same rule to any vehicle with flashing or hazard lights, including tow trucks, highway maintenance crews, utility workers, and disabled vehicles on the shoulder.5National Highway Traffic Safety Administration. Move Over: It’s the Law Some states add jail time when a move-over violation injures or kills an emergency worker.
What an Illegal Pass Costs You
Improper passing on the right is a moving violation in every state. The base fine varies, but once court costs and administrative fees are added, a single ticket often runs several hundred dollars out of pocket. Your state’s motor vehicle agency will also add demerit points to your driving record, with the number varying by jurisdiction.
The expensive part comes later. Insurers treat a moving violation as a sign of higher risk, and premium increases from a single ticket typically last around three years. Drivers who already have points on their record can trigger a suspension or a mandatory defensive driving course with one more infraction. Some states let you take traffic school voluntarily to offset points, but only if you haven’t used that option recently.
CDL Holders
If you hold a commercial driver’s license, the stakes change. Federal regulations classify “making improper or erratic traffic lane changes” as a serious traffic violation. A second serious violation within three years disqualifies you from operating any commercial vehicle for 60 days; a third within the same window brings a 120-day disqualification.6eCFR. 49 CFR 383.51 – Disqualification of Drivers
The disqualification applies even when the violation happens in your personal car. Your employer is also barred from letting you drive commercially once they know or should know you’re disqualified. For a professional driver, a ticket that would be a nuisance for anyone else can mean months without work.
