How Liability Is Assigned in a T-Bone Crash at a Louisiana Intersection

T-bone crashes are among the most dangerous collisions on Louisiana roads. When one vehicle slams into the side of another at an intersection, the injuries can be severe and the legal questions complicated. If you were hit in a side-impact crash, you need to know how fault is determined and who pays for your damages. Getting liability wrong or not understanding it at all can cost you thousands of dollars in medical bills, lost wages, and vehicle repairs that should have been covered.

This article breaks down exactly how liability is assigned in a T-bone crash at a Louisiana intersection, what evidence matters most, and what steps you can take to protect your claim.

What exactly is a T-bone crash, and why is fault harder to determine?

A T-bone crash, also called a broadside or side-impact collision, happens when the front of one vehicle strikes the side of another. These crashes typically occur at intersections when one driver fails to yield, runs a red light, or makes an improper turn.

Fault in a T-bone crash is often harder to pin down than in a rear-end collision because both drivers may have had the right of way or both may claim they did. Unlike a rear-end crash where the trailing driver is almost always at fault, a side-impact collision at an intersection can involve competing versions of events. Was the light red or green? Who entered the intersection first? Did either driver make an illegal turn?

Louisiana's traffic laws and intersection accident fault determination rules provide the framework for answering these questions, but the facts of each case drive the outcome.

Who is typically found at fault in a Louisiana T-bone intersection crash?

The driver who violated a traffic law or failed to yield the right of way is usually found at fault. Here are the most common scenarios:

Running a red light or stop sign. The driver who entered the intersection against a traffic signal is almost always assigned primary fault. Red light camera footage and traffic camera evidence can be powerful proof in these cases.
Failing to yield during a left turn. Louisiana law requires left-turning drivers to yield to oncoming traffic. If a driver turns left in front of an oncoming vehicle and causes a T-bone, the turning driver is typically at fault.
Running a stop sign on a side street. A driver who blows through a stop sign and enters an intersection where cross-traffic has the right of way will usually bear full responsibility.
Making an illegal U-turn. If a driver makes an illegal or poorly timed U-turn and gets struck from the side, fault will likely fall on that driver.
Speeding through a yellow light that turned red. A driver who accelerates to beat a yellow light and enters the intersection after it turns red can be found at fault even if they believed they had the right of way.

What evidence is used to assign fault in a side-impact crash?

Insurance companies and courts look at multiple types of evidence to figure out who caused the crash. The stronger your evidence, the stronger your claim.

Traffic camera and red light camera footage. Many Louisiana intersections have cameras that record violations. This footage can show exactly who had the green light and when each vehicle entered the intersection.
Police reports. The responding officer's report often includes a preliminary fault assessment, diagrams of the crash, and whether either driver received a citation.
Witness statements. Independent witnesses people who were not in either vehicle can provide unbiased accounts of what happened.
Vehicle damage patterns. Where the damage is located on each vehicle tells a story. Front-end damage on one car and driver-side damage on the other can confirm the angle of impact and help reconstruct how the crash occurred.
Skid marks and road debris. Physical evidence at the scene can show speeds, directions of travel, and whether a driver attempted to brake.
Electronic data (black box data). Modern vehicles record speed, braking, and steering inputs in the seconds before a crash. This data can confirm or contradict a driver's version of events.
Cell phone records. If distraction is suspected, phone records can show whether a driver was texting or talking at the time of the crash.

What if both drivers share some fault for the T-bone crash?

Louisiana follows a pure comparative negligence system. This means you can still recover damages even if you were partly at fault your compensation is simply reduced by your percentage of responsibility.

For example, if you suffered $100,000 in damages but were found 30% at fault because you were slightly speeding, you could still recover $70,000. Understanding how comparative negligence works in Louisiana intersection collision claims is important because insurance companies will try to shift as much blame onto you as possible to reduce what they have to pay.

This system means that even partial fault does not bar your claim entirely. But it also means the other side has a financial incentive to argue you were more responsible than you actually were.

How do insurance companies handle T-bone crash liability disputes?

Insurance adjusters are not on your side. Their job is to minimize what the company pays out. Here is what typically happens:

Both insurers investigate. Each driver's insurance company will review evidence, talk to their own policyholder, and try to build a version of events favorable to their side.
Liability may be disputed. In T-bone crashes, it is common for both insurance companies to argue their driver had the green light. Without clear evidence like camera footage or credible witnesses, these disputes can drag on.
Lowball settlement offers. If liability is murky, the other driver's insurer may offer a low settlement hoping you will take it out of frustration or financial pressure.
Recorded statements are used against you. Insurance adjusters may ask for a recorded statement early on, before you fully understand your injuries or the facts. Anything you say can be used to reduce your claim.

Do not give a recorded statement to the other driver's insurance company without understanding your rights first.

What are the most common mistakes people make after a T-bone intersection crash?

Admitting fault at the scene. Saying "I'm sorry" or "I didn't see you" can be twisted into an admission of liability later. Stick to exchanging information and let the investigation determine fault.
Not calling the police. A police report creates an official record of the crash. Without one, it becomes your word against the other driver's.
Failing to gather evidence. Take photos of the intersection, the traffic signals, vehicle damage, skid marks, and your injuries. If there are witnesses, get their names and phone numbers.
Waiting too long to file a claim. Louisiana has a strict deadline for filing injury lawsuits. Missing the statute of limitations for intersection crash injury claims can permanently destroy your case, no matter how strong the evidence is.
Accepting the first settlement offer. Early offers are almost always far less than what your case is worth, especially before you know the full extent of your injuries.
Posting about the crash on social media. Insurance companies monitor social media. A photo of you smiling at a family event can be used to argue your injuries are not serious.

Can a left-turning driver ever avoid fault in a T-bone crash?

Sometimes, yes. A left-turning driver is not automatically at fault in every T-bone crash. If the oncoming driver was speeding excessively, ran a red light, or was otherwise violating traffic laws, the left-turning driver may share less fault or none at all. For instance, if a driver was making a protected left turn on a green arrow and the other driver blew through a red light, the left-turning driver would likely not be at fault.

The details matter enormously. Intersection signal timing, witness accounts, and camera footage all play a role in sorting out what really happened.

What should you do right now if you were in a T-bone crash at a Louisiana intersection?

Get medical attention immediately. Even if you feel okay, some injuries like internal bleeding, concussions, and soft tissue damage may not show symptoms for hours or days.
Report the crash to your insurance company. Give them basic facts, but do not provide a recorded statement to the other driver's insurer without legal advice.
Preserve all evidence. Keep copies of the police report, medical records, photos, repair estimates, and any communication with insurance companies.
Do not sign anything from the other driver's insurance company without understanding what you are agreeing to.
Consult with a Louisiana car accident attorney. A lawyer experienced with intersection crash cases can evaluate your claim, deal with the insurance companies, and make sure you do not miss any critical deadlines.

Practical checklist for protecting your T-bone crash claim:

✅ Get a police report filed at the scene or as soon as possible after
✅ Photograph the intersection, signals, vehicle damage, and your injuries
✅ Collect names and contact information of all witnesses
✅ Seek medical evaluation within 24 to 48 hours
✅ Keep a written record of your symptoms and how injuries affect daily life
✅ Do not give recorded statements to the other driver's insurer
✅ Track all expenses: medical bills, lost wages, transportation costs, and repair bills
✅ Understand the filing deadline so you do not lose your right to sue
✅ Speak with an attorney before accepting any settlement offer
