Louisiana Failure to Obey Traffic Signals Lawyer

Louisiana law requires every driver to obey traffic control devices under La. R.S. 32:231 and La. R.S. 32:232, and a violation of those statutes is direct evidence of negligence in a personal injury case. La. R.S. 32:232 defines what each signal color means: green means proceed, and red means stop.

Trey Morris Injury Lawyers has handled Louisiana automobile injury cases for over 20 years, including many intersection crashes caused by drivers who ignored traffic controls.

Why Drivers Run Red Lights and Ignore Traffic Signals in Louisiana

negligence per se

A doctrine some states use to treat breaking a safety statute as automatic proof of negligence. Louisiana courts reject it: a violation is evidence of fault, but liability still depends on whether the rule was meant to prevent this kind of harm and whether the violation caused it.

Louisiana law requires every driver to obey traffic control devices. La. R.S. 32:231 and La. R.S. 32:232 set out that obligation clearly. A driver who violates those statutes has done more than make a bad decision. They have broken a safety law, and that violation is evidence of fault in the civil case.

The causes of signal-running break into several categories. Distraction is first. Cell phone use, eating, conversations, and dashboard screen interactions all pull a driver’s attention away from the intersection ahead. Impairment is second. Alcohol, drugs, and prescription medications all slow reaction time and impair the judgment needed to process a changing signal. Fatigue matters too. A drowsy driver entering an intersection may not register the red until it is too late. Road rage is a distinct category. Some drivers run signals deliberately, choosing speed and anger over compliance.

Louisiana enacted a hands-free driving law effective August 1, 2025. Full fines became enforceable January 1, 2026. The law prohibits holding a phone while driving and doubles fines for violations that occur in construction zones or involve a crash. This matters for your claim. If the driver who hit you was holding a phone, that violation is evidence of distracted driving layered on top of the signal violation.

The data on signal-running is consistent. The Insurance Institute for Highway Safety (IIHS) reports that red light running kills approximately 1,000 people per year nationwide. AAA research estimates at least two people die daily in the United States from crashes caused by drivers who ignored traffic signals. Intersection crashes are not random. They are caused.

Evidence at intersections disappears fast. Surveillance footage gets overwritten. Signal timing records are not preserved automatically. We send a preservation letter once the facts give us a legitimate basis for one, and moving as promptly as the law permits helps keep the proof in a signal case intact. The letter asks the other driver and their insurer to keep the vehicle and its event data recorder, and asks nearby businesses to keep their camera footage, because speed, braking and the state of the light when each car entered the intersection are what show who ran the signal.

Types of Intersection Crashes Caused by Signal Violations

T-bone collisions, rear-end crashes, left-turn impacts, and pedestrian strikes are all common consequences of signal violations. The type of collision determines the injury pattern, the vehicle damage analysis, and the sequence of events that liability reconstruction must establish.

T-bone collisions are the most severe consequence of running a red light. One driver proceeds with a green signal; the other enters the intersection against the red. The result is a side-impact at full travel speed. Car doors provide significantly less crash protection than front and rear vehicle structures. The occupant on the struck side absorbs the full impact with minimal crush distance between them and the striking vehicle. Injury severity in angle impacts is consistently higher than in rear-end crashes at comparable speeds.

Rear-end collisions at signals happen when a driver stops for a red light and the vehicle behind fails to stop in time. These are common at high-speed approaches where following distances are short. The stopped driver did nothing wrong. The driver behind failed to maintain a safe distance. Left-turn crashes occur when a driver proceeds through a green light while a turning driver runs a yellow or red. Pedestrian and cyclist strikes at intersections are particularly serious. A person on foot or on a bicycle has no protective structure around them when struck by a signal-runner.

Multi-vehicle crashes happen when one signal-runner triggers a chain reaction. The at-fault driver strikes one vehicle, and that vehicle is pushed into another. Identifying the original signal violation as the cause of all downstream impacts is essential for proper liability attribution. Crash geometry matters. Which side of your vehicle was struck, at what angle, and at what estimated speed all inform what injuries are likely and what evidence to look for.

How Do You Prove the Other Driver Ran a Red Light?

Liability in a signal-violation crash rests on proving that the other driver entered the intersection against a red light. When the at-fault driver disputes this, the case becomes an evidence contest.

Traffic camera and red light camera footage is the strongest evidence available. It is timestamped, objective, and shows the signal state at the moment of entry. Not every intersection in Louisiana has a camera, but many urban and suburban intersections do. This footage is typically overwritten within 30 to 90 days. Preserving it requires prompt action. Dashcam footage from your vehicle, from a bystander’s vehicle, or from a nearby business can serve the same function.

The Louisiana Uniform Motor Vehicle Traffic Crash Report documents the officer’s observations at the scene. Officer notations on point of impact, vehicle rest positions, skid mark measurements, and witness statements are all recorded here. Physical evidence is not subjective. Skid marks show where braking began relative to the intersection. The point of impact on the vehicles shows which direction each was traveling. Vehicle rest positions after impact show post-impact movement.

EDR

Event Data Recorder. An electronic module in most modern vehicles that captures pre-crash speed, braking application, throttle position, and seatbelt status in the seconds before impact. Sometimes called a black box.

Signal timing records are another tool. Traffic signal phasing is programmed and recorded by city traffic engineering departments or LaDOTD. A public records request can obtain the signal timing plan for that intersection and confirm that the other driver could not have had a green when they entered. The EDR captures speed, braking, and throttle data in the seconds before impact. If the at-fault driver never braked, the EDR shows it.

Expert accident reconstruction is used when evidence conflicts or the defendant’s account is inconsistent with the physical evidence. Reconstructionists analyze crush depth, vehicle kinematics, skid patterns, and sight lines to establish what actually happened.

Obtaining signal timing data through public records is specific, technical work that requires knowing who to ask and how. Our car accident lawyers know what the evidence preservation checklist looks like for intersection crash cases.

Louisiana Laws Governing Traffic Signal Violations

Louisiana law (La. R.S. 32:231 and La. R.S. 32:232) requires every driver to obey traffic control devices, and a violation of these statutes is direct evidence of negligence in a personal injury case. Understanding the full legal framework matters for your claim.

La. R.S. 32:231 is the baseline rule: every driver must obey traffic control devices unless directed otherwise by a police officer. La. R.S. 32:232 defines what each signal color means. Green means proceed. Yellow means the signal is about to change to red. Drivers are required to prepare to stop when they can do so safely. Red means stop. Louisiana law also addresses red arrow signals specifically. A driver facing a red arrow signal is prohibited from entering the intersection until a green arrow is displayed. This matters for turning-lane crashes, which are a common pattern at signalized intersections with dedicated turn phases.

La. R.S. 32:233 covers pedestrian signals and the obligations of drivers when pedestrians are present. La. R.S. 32:393.1 governs automated red light cameras. A camera citation is a civil penalty only. It does not carry license points and is separate from the civil injury liability analysis. A driver can receive both a camera citation and be held civilly liable for injuries they caused.

Negligence Per Se

A doctrine some states use to treat breaking a safety statute as automatic proof of negligence. Louisiana courts reject it: a violation is evidence of fault, but liability still depends on whether the rule was meant to prevent this kind of harm and whether the violation caused it.

Louisiana courts do not apply the negligence per se doctrine (Faucheaux v. Terrebonne Consol. Gov’t, 615 So.2d 289 (La. 1993)). A violation of La. R.S. 32:231 or 32:232 is evidence of negligence. It does not automatically resolve the case, but it strengthens the injured party’s position on liability when the violation caused the crash.

Comparative Fault

A legal rule that reduces your recovery by your percentage of fault. In Louisiana, if you are 51% or more at fault, you recover nothing. If you are 50% or less at fault, your damages are reduced proportionally.

La. C.C. Art. 2323 governs Comparative Fault in Louisiana. The 51% bar took effect January 1, 2026 as part of tort reform. A driver who ran a red light will almost always hold the majority of fault. But insurance adjusters will look for any evidence that you were speeding, distracted, or failed to take evasive action to push your fault percentage up.

Louisiana also imposes headlight requirements under La. R.S. 32:301 and La. R.S. 32:322. Headlights are required from sunset to sunrise and during rain or low visibility. In Louisiana, where rain and fog are common, failure to use headlights in poor conditions can be raised as a concurrent negligence factor. If the at-fault driver claims they could not see the signal clearly, their visibility obligations cut both ways.

Prescriptive Period

Louisiana’s term for the legal deadline to file a lawsuit. For personal injury claims, it is two years from the date of injury under La. C.C. Art. 3493.1, effective July 1, 2024.

You have two years from the date of the accident to file a personal injury lawsuit in Louisiana under La. C.C. Art. 3493.1. This Prescriptive Period became effective July 1, 2024 when the legislature extended the deadline from one year.

Injuries Common in Red Light and Signal Violation Crashes

Side-impact crashes at intersections produce specific injury patterns that differ from rear-end collisions. The lateral force of a T-bone impact transfers through the vehicle door and frame directly into the occupant. The door offers minimal crush distance.

Cervical spine injuries are common. The head moves laterally with the impact and then rebounds, producing hyperflexion and hyperextension in combination with rotation. Thoracic spine fractures occur when the chest wall is compressed against the seatbelt during lateral deceleration. Both injury types require MRI imaging to document. X-rays will not show soft tissue or disc injuries.

TBI

Traumatic Brain Injury. A disruption in normal brain function caused by a blow or jolt to the head. Severity ranges from concussion to diffuse axonal injury. Symptoms can include headache, cognitive impairment, memory loss, mood changes, and sleep disruption.

TBI is a significant risk in angle impacts. The brain is not designed to absorb rotational forces. When the head snaps laterally, the brain undergoes rotational acceleration that can cause diffuse axonal injury even without a direct blow to the skull. Symptoms of TBI are not always immediate. Headaches, cognitive fog, and emotional changes that develop in the days after a crash can indicate a brain injury that was not apparent at the scene.

Rib fractures, sternal fractures, and pelvic injuries result from seatbelt loading and door intrusion. Internal organ injuries (spleen, liver, kidney) occur when the abdominal cavity is compressed during a side impact. Lower extremity injuries happen when the door and frame intrude into the passenger compartment. These are particularly severe in narrow-vehicle collisions and in crashes involving commercial vehicles or trucks.

Soft tissue injuries require thorough documentation. An MRI is essential for establishing the severity of disc injuries, muscle tears, and ligament damage. Physicians who rely on X-ray alone will miss findings that matter for your case. When you work with Trey Morris Injury Lawyers, we coordinate with your treating physicians to ensure the imaging protocol captures everything relevant. If you need to see a specialist, we can help identify appropriate providers.

What Compensation Does Louisiana Law Allow After a Traffic Signal Violation Crash?

Loss of Earning Capacity

The difference between what you could have earned over your working lifetime before the injury and what you can earn now. Calculated by vocational and economic experts and presented as a present-value figure.

Loss of Consortium

A claim by the injured person’s close family for the loss of companionship, affection, and support caused by the injured person’s condition. Louisiana gives it to the same relatives who could bring a wrongful death claim, starting with the spouse and children. It is a separate damage category and is filed alongside the injured person’s claim.

Louisiana law divides compensable damages into two categories. Economic damages are calculable: past and future medical expenses, lost wages from time missed at work, Loss of Earning Capacity, property damage, and the cost of future medical care. Non-economic damages cover pain and suffering, mental anguish, loss of enjoyment of life, and Loss of Consortium.

General damages for personal injury are not subject to a dollar cap in most Louisiana automobile cases. This is unlike medical malpractice, where non-economic damages are capped. Insurance company limits, not statutory caps, are typically the practical ceiling on recovery in auto cases.

Two statutory provisions affect the recovery calculation in signal-violation cases. The first is Louisiana’s No Pay No Play statute, La. R.S. 32:866. If you were uninsured at the time of the crash, you cannot recover the first $100,000 in bodily injury damages and the first $100,000 in property damage from the at-fault driver’s insurer, even if the at-fault driver is 100% responsible. This is a penalty for operating a vehicle without insurance. If you were insured, it does not apply to you.

UM/UIM

Uninsured/Underinsured Motorist coverage. A provision in your own auto policy that pays your damages when the at-fault driver has no insurance (UM) or has insufficient insurance (UIM) to cover your losses. A Louisiana auto policy generally includes this coverage unless a named insured rejected it on the form the insurance commissioner prescribes.

The second is UM/UIM coverage under La. R.S. 22:1295. If you accepted it, your own policy provides an additional recovery layer when the at-fault driver has minimum limits or no insurance. UM/UIM limits do not stack across the vehicles on a policy.

If the crash caused a death, the available damages expand to include wrongful death and survival action claims. See our wrongful death claims page for more on how those claims are structured under Louisiana law.

We review UM/UIM coverage on both sides so we know the full recovery landscape.

How Insurance Companies Handle Red Light Accident Claims

Insurance adjusters are not neutral. They work for the insurance company. Their job is to pay as little as possible on claims. Understanding how they work in signal-violation cases helps you avoid the most common mistakes.

The first tactic is the liability dispute. Even when a driver was clearly cited for running a red light, the insurer may argue that the signal phasing was ambiguous, that you entered the intersection on a stale green, or that you had time to avoid the collision. They commission their own investigations. They interview their own insured. They look for any argument that shifts fault to you.

The second tactic is the recorded statement. Questions are phrased to elicit answers that establish your awareness of the signal, your speed, and your reaction time. Do not give a recorded statement to the other driver’s insurer without speaking to an attorney first.

The comparative fault tactic is specific to signal-violation cases. Adjusters know that under La. C.C. Art. 2323, pushing your fault percentage above 50% cuts off your recovery entirely. They look for any evidence you were speeding, failed to keep a proper lookout, or had a clear opportunity to avoid the collision. This is why the evidence analysis matters. An established speed reconstruction and a confirmed signal timing sequence eliminate the arguments they rely on.

Direct Action Statute

La. R.S. 22:1269, which allows an injured person to sue the at-fault driver’s insurance company directly only in limited situations, such as when the insured is bankrupt, insolvent, or deceased, or cannot be served.

Louisiana’s Direct Action Statute (La. R.S. 22:1269) allows a lawsuit directly against the at-fault driver’s insurer only in limited situations, such as when the insured is bankrupt, insolvent, or deceased, cannot be served, or when the claim is against your own uninsured motorist carrier. In most cases the suit names the at-fault driver, and the insurer stays out of the caption.

Louisiana’s minimum bodily injury liability coverage is $15,000 per person and $30,000 per occurrence under La. R.S. 32:900. Many serious intersection crash injuries far exceed those limits. When minimum limits are in play, UM/UIM coverage from your own policy becomes the primary recovery mechanism. Our Louisiana automobile injury lawyers evaluate both sides of the coverage picture before we advise you on strategy.
