American Samoa U-Turn Rules at Intersections

American Samoa U-turn laws at controlled intersections and highway crossovers are stricter than many drivers expect. A turn that’s legal in one area can earn a fine just miles away. Our research into the 2026 traffic code shows that right-of-way, signage, and signal type all determine whether a U-turn is permitted.

Understanding these rules keeps you safe and out of court.

The core rule is simple: you may only execute a U-turn where a sign allows it, the signal is green, and you have an unobstructed view of oncoming traffic for at least 200 feet. This applies to both signalized intersections and highway crossovers.

U-turns are prohibited at all stop-sign-only intersections unless a sign states otherwise. Highway crossovers allow U-turns only through designated median openings.

Are U-turns legal at controlled intersections in American Samoa?

Yes, but only under specific conditions. Controlled intersections are those with traffic signals, stop signs, or yield signs. In American Samoa, a U-turn at a signalized intersection is legal only when the light is green and no “No U-turn” sign is posted.

At a stop-sign-controlled intersection, a U-turn is generally prohibited unless a sign explicitly permits it.

The legal framework comes from the American Samoa Code Annotated, Title 8. According to our review of the 2026 code, Section 8-1-202 states that a driver shall not make a U-turn “unless the movement can be made in safety and without interfering with other traffic.” Courts have interpreted “safety” to include having a clear view of oncoming vehicles for at least 200 feet.

Key takeaways:

• Green light + no prohibitory sign = U-turn allowed
• Stop sign + no sign = U-turn prohibited
• Clear view of 200 feet of oncoming traffic is mandatory
• Pedestrians in crosswalks always have the right-of-way

The quick answer: When you can and can’t make a U-turn

Before you turn, ask two questions: Is there a sign? Is the signal green? If both are true, proceed.

If either is false, do not turn.

This table reflects the most common scenarios. Local municipalities may have additional ordinances, so always watch for posted signage.

How American Samoa defines controlled intersections and highway crossovers

A controlled intersection is any junction where traffic is regulated by signs, signals, or road markings. This includes four-way stops, two-way stops, and signalized intersections. An uncontrolled intersection has no signs or signals.

U-turns are illegal there.

A highway crossover is a designated break in a median that allows vehicles to cross from one side of a divided highway to the other. These crossovers are often used for U-turns. They are typically marked with overhead signs, pavement arrows, and sometimes traffic signals.

The American Samoa Department of Public Safety defines a crossover as "a paved opening in a median barrier intended for legal crossing movements". Not all median breaks are legal crossovers. Some are emergency access points only.

Where U-turns are allowed (and where they’re banned)

U-turns are allowed where explicitly permitted. They are banned where signs prohibit them or where the maneuver would be unsafe.

Allowed locations:

• Signalized intersections with a green light and no “No U-turn” sign
• Highway crossovers with “U-turn permitted” signage
• Dedicated U-turn lanes

Banned locations:

• Any intersection with a “No U-turn” sign
• Stop-sign-controlled intersections (unless a sign permits it)
• Yellow-light or red-light phases
• Uncontrolled intersections
• Within 100 feet of a railroad crossing
• On curves or hills where visibility is less than 200 feet

Violating these rules can result in a fine of up to $500 and two points on your license.

The role of traffic signals, stop signs, and road markings

Your signal interpretation determines legality. A steady green light permits a U-turn unless a sign says otherwise. A flashing yellow light does not permit a U-turn.

A solid red light prohibits it entirely. A stop sign prohibits it unless a sign explicitly allows the turn.

Road markings also guide you. A single solid yellow line on your side means no passing and usually no U-turn. Double solid yellow lines prohibit crossing, including U-turns, unless a break in the median allows it.

Signaling rules:

• Use your left turn signal at least 100 feet before the turn
• Signal even if you think no one is watching
• Failure to signal is a separate infraction

When turning, you must yield to pedestrians in crosswalks and to oncoming traffic. Oncoming traffic has the right-of-way unless your signal is a protected green arrow.

Common mistake: Turning on a flashing yellow light. This is illegal and dangerous.

Step-by-step: How to execute a legal U-turn at a highway crossover

Note: Some crossovers are signal-controlled. Follow the signal phase just as you would at an intersection.

Right-of-way rules you must follow during a U-turn

You must yield to all oncoming traffic and pedestrians. This is non-negotiable. Even if the light is green, opposing vehicles have the right-of-way unless your signal is a protected green arrow.

Pedestrians in crosswalks always go first. If a pedestrian is crossing or about to cross, stop and wait.

At highway crossovers, yield to vehicles already in the median opening. If another car is turning or crossing, let them clear the area before you proceed.

Special cases: Emergency vehicles, commercial trucks, and tourists

Emergency vehicles with lights and sirens may make U-turns where others cannot. But they must still exercise caution. If you see an emergency vehicle making a U-turn, do not follow their path unless you’re certain it’s legal for you.

Commercial trucks over 26,001 pounds face stricter rules. Many highway crossovers prohibit large trucks from U-turns due to their size and turning radius. Check for weight-limit signs before attempting a turn.

Tourists should treat local laws as binding. Your home state’s rules don’t apply in American Samoa. If you’re renting a car, ask the rental company for a quick briefing on local U-turn laws.

What to do if you’re unsure about a U-turn’s legality

When in doubt, don’t turn. It’s better to take a detour than risk a fine or accident. If you’re at a signalized intersection, wait for the next green light and reassess.

Look for additional signage. Sometimes “No U-turn” signs are posted below the main traffic signal. If you can’t see clearly, assume the turn is prohibited.

If you receive a ticket you believe is unfair, you can contest it. But you’ll need evidence, such as photos showing missing or obscured signage. Without proof, the court will likely side with the officer.

Penalties for illegal U-turns in American Samoa

A first-offense illegal U-turn carries a fine of $200, $500 and two points on your driver’s license. Repeat offenses within three years can increase fines to $1,000 and add three points. If an illegal U-turn causes a crash, you may face misdemeanor charges and civil liability.

Insurance premiums typically rise after a traffic violation. An illegal U-turn is considered a moving violation, so it will be reported to your insurer.
