Maine Left Turn Right of Way Rules

Left turns cause more crashes than almost any other driving maneuver, and Maine has specific right-of-way rules that determine who's responsible when things go wrong. Whether you're driving through an intersection in Portland or turning onto a rural road in Aroostook County, understanding these rules protects your safety and your legal rights. If you've already been hurt in a left-turn collision, knowing the law also helps you figure out whether you have a valid injury claim.

What Does Maine Law Actually Say About Left Turns and Right of Way?

Maine's traffic code is straightforward on this point. Under Title 29-A, §2054, a driver making a left turn must yield the right of way to any vehicle approaching from the opposite direction that is close enough to create an immediate hazard. In plain language: if you're turning left and another car is coming straight through the intersection, you have to wait.

This rule applies at intersections with traffic signals, stop signs, and even uncontrolled intersections. It also applies when turning left into a driveway, parking lot, or side road. The law doesn't give the left-turning driver a pass just because they arrived first or because they think they have enough time.

When Does the Left-Turning Driver Have the Right of Way in Maine?

There are a few situations where a left-turning driver does have the right of way:

Protected green arrow signal: If you have a green left-turn arrow, oncoming traffic should be stopped. You have the right of way during that signal phase.
Oncoming traffic has a red light: When all opposing traffic is stopped at a red light, a left-turning driver with a green light can proceed.
The approaching vehicle is far enough away: The law says you must yield to vehicles that are an "immediate hazard." If the nearest oncoming car is far enough away that you can complete your turn safely, you may proceed.
All-way stop intersections: At a four-way stop, the standard right-of-way rules apply. If you arrived first and the opposing traffic is waiting, you can turn left when it's your turn.

The gray area is that third point. "Immediate hazard" is a judgment call, and it's the exact spot where most left-turn accident fault disputes begin.

Who Is at Fault in a Maine Left-Turn Accident?

In the majority of cases, the left-turning driver is found at fault. Insurance companies and courts start with the assumption that the person turning left had a duty to yield. But that assumption can be challenged.

The other driver might share fault if they were:

Speeding well over the posted limit
Running a red light or stop sign
Distracted by a phone or other device
Driving without headlights at night

Maine follows a modified comparative fault rule. Under this system, you can still recover damages as long as you are less than 50% responsible for the crash. Your compensation is reduced by your percentage of fault. For example, if you were turning left and found 30% at fault because the other driver was speeding, your total recovery would be reduced by 30%.

What Are the Most Common Mistakes Drivers Make With Left Turns?

Understanding the right-of-way rules is one thing. Applying them correctly in real traffic is another. Here are the mistakes that lead to the most crashes and legal trouble:

Misjudging the speed of oncoming traffic. Drivers often think they have enough time to turn, but underestimate how fast the other car is traveling. A car going 45 mph covers about 66 feet per second.
Rushing through a yellow light. Trying to beat the light by making a quick left turn is one of the most dangerous habits at intersections.
Assuming oncoming traffic will slow down. Never assume the other driver sees you or will yield. The law puts the burden on the left-turning driver.
Not checking for a second lane of traffic. If the oncoming car in the near lane stops to let you turn, traffic in the far lane may still be coming. This is a common cause of T-bone collisions.
Failing to use a turn signal. Maine law requires signaling at least 100 feet before turning. Not signaling can contribute to fault.

What Should You Do Right After a Left-Turn Accident in Maine?

The steps you take in the first hours and days after a crash directly affect your safety and any potential claim:

Call 911 and get medical attention. Even if injuries seem minor, get checked. Adrenaline masks symptoms.
Document everything at the scene. Take photos of vehicle positions, damage, skid marks, traffic signals, and road conditions.
Get witness information. Independent witnesses are often the deciding factor in left-turn cases.
Do not admit fault. Stick to the facts when speaking with police. Don't say "I'm sorry" or "I thought I had time."
Report the crash to your insurance company but avoid giving a recorded statement to the other driver's insurer without legal advice.

How Do Maine Courts Handle Left-Turn Disputes?

When fault is contested, courts look at the full picture. They examine police reports, witness statements, traffic camera footage, vehicle damage patterns, and crash reconstruction reports. The physical evidence often tells the real story. For example, the point of impact on the vehicles can show exactly where each car was in the intersection at the moment of collision.

Judges and juries in Maine apply the "reasonable driver" standard. Would a careful, reasonable driver in the same situation have believed it was safe to turn? If the answer is no, the left-turning driver is usually found negligent.

This is why working with an attorney who understands Maine's left-turn accident laws matters. A skilled lawyer can gather the evidence needed to prove what actually happened.

What If the Other Driver's Insurance Denies Your Claim?

Insurance companies often deny or lowball left-turn accident claims by blaming the turning driver entirely. They know that Maine's right-of-way law appears to favor their insured. But partial fault doesn't bar your claim, and the initial determination by an insurance adjuster is not final.

An experienced Maine car accident lawyer who handles left-turn collisions can challenge the insurance company's version, bring in crash reconstruction experts, and negotiate for full compensation for your medical bills, lost wages, and pain and suffering.

Do These Rules Change at Uncontrolled Intersections or Private Roads?

The yield-the-right-of-way rule for left turns applies on all public roads in Maine, including uncontrolled intersections where there are no signs or signals. At those intersections, the driver making the left turn still must yield to approaching traffic.

On private roads, parking lots, or driveways, Maine's traffic statutes may not apply in the same way, but the general negligence principles still hold. If a driver makes a careless left turn on private property and causes a crash, they can still be held liable for damages under Maine's civil negligence laws.
