Maryland U-Turn Laws: Controlled Intersections & Crossovers

Maryland U-turn laws at controlled intersections and highway crossovers trip up even experienced drivers. The rules change depending on where you are, what signs are posted, and how the road is designed. Per the Maryland Vehicle Code, a single wrong turn can mean a fine, points on your license, or worse, a collision.

The state follows the Manual on Uniform Traffic Control Devices (MUTCD) for signage, but local ordinances add layers. As of 2026, enforcement is especially strict in high-traffic areas like Baltimore and Montgomery County.

Always yield to oncoming traffic and pedestrians. Violations carry fines up to $130.

Where U-Turns Are Legal (and Where They’re Not)

U-turns are generally allowed in Maryland unless a sign or road design says otherwise. At controlled intersections (those with traffic lights or stop signs), you can make a U-turn if:

• No "No U-Turn" sign (R3-4 per MUTCD) is posted
• You have a clear view of oncoming traffic for at least 200 feet
• You don’t interfere with other vehicles or pedestrians

U-turns are illegal in these spots:

• Where a "No U-Turn" sign is visible
• At intersections with a traffic light showing a red arrow for left turns
• On divided highways unless there’s a designated crossover
• Near curves, hills, or other spots with limited visibility
• In school zones during active hours

Controlled Intersections: The Rules You Need to Know

Controlled intersections have traffic signals or stop signs, and the rules here are strict. You can make a U-turn only if:

• The intersection isn’t marked with a "No U-Turn" sign
• You’re in the leftmost lane (or the lane designated for left turns)
• You yield to all oncoming traffic and pedestrians

If the light is green, you can turn after yielding. If it’s red, you must come to a complete stop first, then proceed only when safe. Maryland treats a U-turn as a left turn followed by a right turn, so the same right-of-way rules apply.

A common mistake is assuming a green light means you can turn immediately. You must still yield to oncoming traffic, including vehicles going straight in the opposite direction.

Highway Crossovers: What’s Allowed and What’s Not

Highway crossovers are the breaks in medians that let you turn around. In Maryland, U-turns here are only legal if:

• The crossover is designed for U-turns (look for pavement markings or signs)
• There’s no "No U-Turn" sign posted
• You have enough space to complete the turn without blocking traffic

Divided highways (like I-95 or US-50) often have medians too narrow for safe U-turns. If there’s no official crossover, turning around is illegal, and dangerous. Police frequently patrol these areas, especially in high-traffic corridors.

The Maryland Department of Transportation (MDOT) confirms that U-turns across a divided highway outside a designated crossover are always prohibited.

Signs That Override Everything

Traffic signs take precedence over general rules. The most critical one is the MUTCD R3-4 sign, a white square with a black U-turn symbol and a red circle/slash. If you see this, U-turns are banned at that location, no exceptions.

Other signs to watch for:

• "No Left Turn" signs often imply no U-turns (since a U-turn starts as a left turn)
• "One Way" signs mean U-turns are illegal in that direction
• "Do Not Enter" signs prohibit U-turns into that lane

Even if no sign is posted, pavement markings can prohibit U-turns. A solid double yellow line means no passing, and often no U-turns. If you’re unsure, assume the turn is illegal until you confirm otherwise.

Step-by-Step: How to Make a Legal U-Turn in Maryland

First, check for signs. If you see a "No U-Turn" or "No Left Turn" sign, stop and find another route.

Next, position your vehicle in the leftmost lane or the lane designated for left turns. Signal your intent early so other drivers know what you’re doing.

At a controlled intersection, come to a complete stop if required. Yield to oncoming traffic and pedestrians before starting your turn. Complete the U-turn without blocking other vehicles or crossing into prohibited areas.

When U-Turns Are Always Illegal (No Exceptions)

U-turns are never allowed in these situations:

• Where a "No U-Turn" sign is posted
• Across a divided highway without a designated crossover
• Near a curve, hill, or other spot with limited visibility
• In a school zone during active hours
• Where a traffic signal explicitly prohibits left turns

Violating these rules can result in a citation. Police in Maryland actively enforce U-turn laws, especially in areas with high accident rates.

Common Mistakes That Get You Ticketed

Assuming a green light means you can turn immediately is a top mistake. You must still yield to oncoming traffic and pedestrians.

Another error is making a U-turn from the wrong lane. Always use the leftmost lane or the lane marked for left turns.

Drivers also get ticketed for U-turns at intersections with a red left-turn arrow. This signal means no left turns, and by extension, no U-turns.

Maryland U-Turn Penalties: Fines, Points, and More

A U-turn violation in Maryland typically carries a fine of $90 to $130. You’ll also receive one point on your driving record.

These points can lead to higher insurance premiums. If you accumulate too many points, your license could be suspended.

Fighting a ticket is possible, but you’ll need to prove the U-turn was legal. This usually requires evidence like photos or witness statements showing no prohibitive signs were present.

Out-of-State Drivers: What’s Different in Maryland?

Maryland’s U-turn laws can differ from neighboring states. For example, Virginia allows U-turns at more intersections unless signs prohibit them.

In Maryland, the rules are stricter, especially on divided highways. Out-of-state drivers often get ticketed for assuming the rules are the same as at home.

If you’re visiting, take extra time to check for signs and road markings. When in doubt, avoid the U-turn and find a safer, legal way to turn around.

Emergency Vehicles and Other Exemptions

Emergency vehicles with lights and sirens can make U-turns where others cannot. This includes police cars, fire trucks, and ambulances responding to calls.

Other exemptions are rare. Construction or utility vehicles may have special permits, but these don’t apply to regular drivers. Always assume standard rules apply unless you’re in an emergency vehicle.

How to Contest a U-Turn Ticket in Maryland

You can fight a ticket by requesting a court date. Gather evidence like photos of the intersection showing no "No U-Turn" signs.

Witness statements can help if someone saw the turn and confirms it was legal. The officer’s testimony carries weight, so your evidence must be strong.

If you win, the fine and points are dismissed. If you lose, you’ll pay the fine and accept the points.

Real-World Scenarios: Legal vs. Illegal U-Turns

At a four-way stop with no signs, a U-turn is legal if you yield properly. But at a red light with a "No Left Turn" sign, it’s illegal.

On a divided highway with a median crossover, U-turns are allowed if no signs prohibit them. Without a crossover, turning across the median is illegal.

In a parking lot, U-turns are generally allowed unless signs say otherwise. But on public roads, the rules are stricter.
