Louisiana T-Bone Accident Lawyers

Trey Morris and Justin Dewett, Morris & Dewett Partners

Side-impact crashes are not like other collisions. The front of one vehicle strikes the side of another. There is almost nothing between the occupant and the point of impact. No one researches Louisiana T-bone accident lawyers for fun. Something happened, and now you need to know what the law says, what evidence matters, and what questions to ask any attorney you are considering.

This page explains how T-bone accident claims work in Louisiana, what changed in the law between 2024 and 2026, and how fault is established when both drivers disagree about who had the right of way. Morris & Dewett has handled Louisiana automobile injury claims for 25 years. Take your time. Do your research. Reach out when you're ready.

What Is a T-Bone Accident?

A T-bone accident is a side-impact or broadside collision. The front of one vehicle strikes the side of another at a roughly perpendicular angle, forming a shape like the letter T. The struck vehicle is hit on its door, rocker panel, or rear quarter. The driver or passenger on that side absorbs the force directly.

Most T-bone crashes happen at intersections. The typical scenario: one driver runs a red light or stop sign and plows into crossing traffic that had the right of way. They also occur in parking lots, at driveway exits, and at highway on-ramps where vehicles merge at right angles to each other. Any situation where two vehicles travel perpendicular paths creates the conditions for a broadside impact.

The structural reality makes these crashes particularly dangerous. Vehicle doors and side panels provide far less protection than the front or rear crumple zones. Federal data from the National Highway Traffic Safety Administration shows that more than 1 in 5 traffic deaths occurs in a side-impact crash. That is a disproportionate fatality rate relative to how often they happen. The terms "T-bone," "broadside collision," and "side-impact crash" refer to the same event. You will see all three used in police reports, insurance documents, and legal filings.

Why Are T-Bone Crashes So Deadly?

T-bone crashes are disproportionately lethal because the door is the only barrier between the occupant and the point of impact. In a frontal collision, the vehicle's front end crumples and absorbs energy over several feet. In a T-bone, that protection is a few inches of steel, glass, and padding.

Comparative fault analysis begins with understanding why the struck occupant is often severely injured even when the impact speed seems moderate. Lateral force at 30 mph can cause injuries that a 30-mph frontal impact would not.

Frontal airbags do not deploy in most T-bone crashes. Side curtain airbags were designed to address this gap, but they deploy only in some vehicles and only when the crash triggers the right sensor pattern. Older vehicles have no side curtain airbags at all. Even in vehicles with them, deployment timing and coverage vary by crash geometry.

The struck vehicle does not just stop. It gets pushed sideways, rotates, and often strikes something else. A secondary impact with a utility pole, guardrail, or another vehicle adds to the total force absorbed by occupants. Rear-seat passengers, children in car seats, and elderly occupants are particularly vulnerable because side reinforcement is lower on rear doors and rear body panels.

Ask any attorney you consult whether they have retained biomechanical engineers on T-bone cases. These experts translate the crash physics into clinical injury explanations that connect the impact to your specific injuries. An attorney who cannot connect crash mechanics to your injury progression will have difficulty rebutting an insurer's argument that the crash was "too minor" to cause serious harm.

For catastrophic injuries resulting from side-impact crashes, separate legal analysis applies.

Who Is at Fault in a T-Bone Accident in Louisiana?

Fault in a T-bone crash turns on right of way: who had the green light, who had the stop sign, and who bore the legal duty to yield before proceeding. Louisiana traffic statutes under La. R.S. Title 32 establish specific rules for each scenario.

The most common fact pattern is clear. A driver runs a red light or stop sign and strikes a vehicle that had the right of way. The driver who ran the control is typically found primarily at fault. Citations issued at the scene for signal violations are powerful evidence. Insurance adjusters rarely contest a case where the police report documents a red-light citation against their insured.

Left-turn T-bone crashes are more disputed. Under La. R.S. 32:122, a driver turning left must yield to oncoming traffic until it is safe to complete the turn. When the turning driver misjudges oncoming speed or proceeds without adequate clearance, they bear primary fault. The oncoming driver will often be accused of speeding, which is the standard defense. How your attorney establishes the actual speed through event data recorder analysis and accident reconstruction determines whether that defense succeeds.

Respondeat Superior applies when the at-fault driver was on the clock for an employer. If a delivery driver or company vehicle driver caused your T-bone crash, the employing company may share liability alongside the driver.

Multi-vehicle fault is also possible. A driver who pushed another vehicle into an intersection through a rear-end impact, or a vehicle parked in a way that blocked sight lines, may share responsibility. Government liability applies when a malfunctioning traffic signal or overgrown vegetation on public property contributed to the crash.

Louisiana's comparative fault rule under La. C.C. Art. 2323, effective January 1, 2026, assigns fault as a percentage to each party. The driver with the right of way may bear some fault if they were speeding or distracted. Adjusters will build the narrative around shared fault to reduce your recovery. A 10% fault increase on a significant claim is a substantial reduction.

Ask any attorney you consult how they handle comparative fault disputes in T-bone cases. Morris & Dewett retains accident reconstructionists on disputed-fault cases before the insurance company's narrative takes hold. We work backward from the physical evidence to establish what each driver was doing before impact.

Evidence That Determines Fault in a T-Bone Crash

Fault in a T-bone crash is rarely decided by a single document. It is built from multiple evidence sources, and the window to preserve the most important evidence is measured in hours, not days.

Traffic camera and dashcam footage is the most decisive evidence when it exists. Intersections in Louisiana cities are covered by municipal traffic cameras, red-light enforcement cameras, and private security systems from adjacent businesses. This footage is routinely overwritten within 24 to 72 hours unless a formal preservation demand is sent. Ask any attorney you consider how quickly they act on camera preservation. If the answer is "we'll get to it this week," the footage is probably gone.

The police report is the first document your attorney will request. It includes the officer's crash diagram, vehicle positions, witness names, any citations issued, and the officer's assessment of fault. A citation for running a red light is powerful supporting evidence. The report is not the final word, but it frames the initial insurance company evaluation.

Spoliation applies to vehicle event data recorders. These devices capture the final seconds before impact: speed, braking force, steering input, and seatbelt status. They must be preserved before the vehicle is repaired or sent to a salvage yard. If the at-fault driver's carrier arranges a quick repair, that data may be gone.

Witness statements carry weight because they come from people with no stake in the outcome. Getting names and contact information at the scene, while people are still there, is critical. A witness's recollection degrades quickly. An investigator who contacts them within 24 hours gets a far more detailed account than one who calls two weeks later.

Cell phone records establish whether the at-fault driver was distracted at the time of impact. These records are subpoenaed. Carriers retain call and data logs for varying periods, so timing matters here as well.

When no camera footage exists, fault analysis shifts entirely to physical evidence. Crush damage vectors indicate the angle of impact and relative speeds. Skid mark patterns show where braking occurred and from which direction. Preservation Letter demands must go out immediately to stop evidence from being lost. Vehicle resting positions are documented in the police report and photographs. Accident reconstructionists analyze this physical evidence to determine which account of events is consistent with the physics.

Insurance adjusters from the at-fault driver's carrier will call you within 24 to 48 hours. They want a recorded statement. That statement will be used to establish facts favorable to their insured. Do not give one without an attorney. Any competent attorney you consult will explain exactly how they handle adjuster contact after you retain them. Morris & Dewett sends a representation letter immediately, which stops the adjuster from contacting you directly.

Injuries Common in T-Bone Crashes

T-bone crashes produce a specific injury profile driven by the lateral force and door intrusion dynamics. The injuries below are not exhaustive, but they are the categories most commonly documented in side-impact cases.

Traumatic brain injury occurs when the head strikes a side window, door frame, A-pillar, or roof during the rotational phase of the crash. Even without direct contact, the rapid deceleration and rotation can cause the brain to move within the skull, producing diffuse axonal injury. Symptoms are not always immediate. Headaches, cognitive slowing, word-finding difficulty, and mood changes that appear 24 to 72 hours after the crash can be connected to the impact. Medical evaluation on the day of the crash, even if nothing is found, documents that you sought care. Follow-up evaluation when symptoms emerge establishes the progression.

Spinal injuries follow from the lateral compression and rotational forces. Cervical (neck) injuries and thoracic (mid-back) injuries are most common in T-bone impacts. Disc herniation at C4-C6 and T6-T10 are frequently documented. In severe cases, spinal cord involvement causes sensory or motor deficits. Spinal treatment costs are typically the largest component of a T-bone injury claim. Surgery, instrumentation, physical therapy, and long-term management add up quickly.

Rib fractures and internal organ damage result from lateral compression of the torso. Rib fractures can puncture a lung, producing a pneumothorax that requires emergency intervention. Spleen, liver, and kidney lacerations from internal compression are serious injuries that are sometimes missed without imaging.

Pelvic fractures occur in low-door-height impacts and in crashes where the door intrudes significantly into the passenger compartment. These are debilitating injuries with extended recovery timelines.

Arm and shoulder injuries are common because occupants instinctively brace themselves. Arm fractures, rotator cuff tears, and shoulder dislocations result from the bracing force combined with the lateral impact.

Soft tissue injuries in T-bone crashes differ from rear-end collision whiplash. Lateral cervical strain, hip ligament tears, and knee injuries from door intrusion are more typical than the neck whiplash pattern. These injuries are contested by insurance adjusters because they do not show on standard imaging. Documenting them requires thorough clinical evaluation and, in some cases, MRI.

Psychological injury is real and compensable. Post-traumatic stress following a severe side-impact crash, particularly one involving a fatality or near-death experience, is a recognized condition requiring documentation and treatment.

When a T-bone crash results in death, Louisiana law provides both survival and wrongful death remedies. See our wrongful death claims page for details on who can file and what damages apply.

Louisiana Laws That Govern T-Bone Accident Claims

Louisiana's 51% comparative fault bar and two-year prescriptive period are the two laws that most directly affect T-bone accident claims. Both changed between 2024 and 2026.

Comparative Fault under La. C.C. Art. 2323, effective January 1, 2026, is the most important rule. If you are 51% or more at fault for the T-bone crash, you recover nothing. Below that threshold, your damages are reduced by your fault percentage. A 30% fault finding on a $200,000 claim leaves you with $140,000. Insurance adjusters build their entire T-bone defense around pushing your fault percentage above 50%.

The Prescriptive Period for personal injury claims is two years from the date of injury under La. C.C. Art. 3493.11, effective July 1, 2024. If someone tells you the deadline is one year, that is the old law. The one-year rule applied to crashes before July 1, 2024. For crashes after that date, two years applies. Any attorney quoting a one-year deadline for a post-July 2024 crash is working from outdated information.

UM/UIM coverage is required by Louisiana insurers under La. R.S. 22:1295 unless you rejected it in writing. If the at-fault T-bone driver carries minimum liability of $15,000 and your injuries exceed that amount, your own UM/UIM policy covers the balance up to your policy limit. Many people do not know they have this coverage until they consult an attorney.

Louisiana's direct action statute, La. R.S. 22:1269, allows you to sue the at-fault driver's insurance company directly. You do not need a judgment against the driver first. This matters in cases where the driver is uncooperative or judgment-proof.

Louisiana's No Pay No Play rule, La. R.S. 32:866, affects uninsured drivers. If you were driving without insurance at the time of a T-bone crash, you face restrictions on recovering the first $15,000 of bodily injury damages and the first $25,000 of property damage, even if the other driver was entirely at fault. This rule penalizes driving without coverage regardless of who caused the crash.

When a T-bone crash is fatal, Louisiana allows a Survival Action under La. C.C. Art. 2315.1 and a Wrongful Death Action under La. C.C. Art. 2315.2. These are separate claims that can be filed simultaneously.

If the T-bone crash happened while you were driving for work, the employer's workers' compensation carrier may have a subrogation interest in your personal injury settlement under La. R.S. 23:1101. Ask any attorney you consult how they handle workers' comp subrogation in third-party crash claims. An attorney who does not address this may negotiate a settlement that the employer's carrier then partially reclaims.

What Damages Can You Recover After a Louisiana T-Bone Crash?

Louisiana law allows recovery for both economic and non-economic losses. The final amount depends on the nature of your injuries, how fault is assigned, and the quality of the evidence built during the case.

Medical expenses include all past and future treatment costs: emergency room care, hospitalization, surgery, imaging, physical therapy, pain management, and any anticipated future procedures. Future medical expenses require expert testimony from treating physicians or medical economists. Without this testimony, future costs are speculative and harder to recover.

Lost wages cover income you could not earn during recovery. Loss of Earning Capacity is a separate and potentially larger category. It applies when the injury permanently limits what you can earn going forward. This requires vocational expert and economic expert testimony to establish.

Pain and suffering damages compensate for the physical and emotional impact of your injuries. Louisiana does not cap general damages for most T-bone accident claims. The amount depends on the severity, duration, and permanence of the harm. Recent tort reform changes in 2024 and 2025 modified certain damages categories; whether those changes apply depends on your crash date.

Property damage covers your vehicle repair or replacement value and any other personal property destroyed in the crash.

Loss of Consortium is a separate claim available to qualifying family members when your injuries affect the relationship.

When you bear partial fault, all damages are reduced by your fault percentage. A $300,000 recovery at 25% fault yields $225,000. A contested 10% increase in your fault assignment costs you $30,000 on that same claim. This is why the fault dispute is as important as the damages figure. Ask any attorney you consult what their specific approach is to defending comparative fault percentages in T-bone cases.

What to Do After a T-Bone Accident in Louisiana

What you do in the hours immediately after a T-bone crash has a direct effect on your legal position. These steps are specific to side-impact crashes.

Stay at the scene. Leaving before police arrive can be characterized as a hit-and-run regardless of fault. If vehicles must be moved for safety, document their exact positions with photographs before moving anything.

Call 911. Even for crashes that seem manageable, a police report creates an official record of what happened, who was involved, and the conditions at the scene. Emergency medical response documents your injuries from the moment of impact.

Photograph everything before it moves or changes. Vehicle positions. The traffic signal display, if visible. Skid marks. Road conditions. Sight lines from each vehicle's approach direction. All vehicle damage. Your injuries. The other driver's license, registration, and insurance card.

Get witness contact information immediately, before people leave. Witnesses are the most perishable evidence at a crash scene. A name and phone number collected at the scene is worth far more than a request through the police report filed a week later.

Seek medical evaluation the same day. T-bone crashes are associated with delayed-onset injuries: traumatic brain injury symptoms, spinal pain, and internal injuries that are not immediately apparent. A medical record from the day of the crash establishes that you sought care. When symptoms emerge later, that record supports your account of the injury timeline.

Do not give a recorded statement to the other driver's insurer without an attorney. They will call quickly. Their job is to establish facts favorable to their insured. A recorded statement is a tool for doing that. Decline until you have counsel.

Preserve your dashcam footage immediately. Do not let the device overwrite the recording. Copy it to a separate drive now. Send preservation demands to the municipality, any business with cameras facing the intersection, and any vehicle owner whose dashcam may have captured the crash. This must happen within 24 to 72 hours.

Do not authorize vehicle repair until the preservation letter has been sent and the event data recorder has been downloaded. Repair processes can destroy or overwrite the black box data. This applies to your vehicle as well as the at-fault driver's vehicle.

Contingency Fee arrangements mean consulting an attorney costs you nothing upfront. Morris & Dewett does not charge for initial consultations and takes T-bone accident cases on contingency. Our fee comes from the recovery. If there is no recovery, there is no fee.

Frequently Asked Questions

Who is at fault in a T-bone accident in Louisiana?

Fault turns on who had the right of way under Louisiana traffic law at the moment of impact. At signalized intersections, the driver who ran the red light or stop sign is typically found primarily at fault. For left-turn T-bone crashes, the turning driver bears the duty to yield to oncoming traffic under La. R.S. 32:122 and is usually found primarily at fault. Louisiana's comparative fault rule under [La. C.C. Art. 2323](https://legis.la.gov/legis/Law.aspx?d=109376), effective January 1, 2026, assigns fault as a percentage to each party. Both drivers can share fault. If you are 51% or more at fault, you recover nothing. Below 51%, your damages are reduced by your percentage.

How long do I have to file a T-bone accident lawsuit in Louisiana?

Two years from the date of the injury under [La. C.C. Art. 3493.11](https://legis.la.gov/legis/Law.aspx?d=1092220), effective July 1, 2024. This statute replaced the old one-year prescriptive period. If your crash occurred before July 1, 2024, the one-year rule may still apply. For crashes after that date, you have two years from the date of injury to file suit. Missing the deadline eliminates your right to recover regardless of how strong your case is.

Can I recover if I was partly at fault for the T-bone crash?

Yes, if your fault is 50% or less. Louisiana's comparative fault rule under [La. C.C. Art. 2323](https://legis.la.gov/legis/Law.aspx?d=109376) reduces your recovery by your fault percentage. If you are 20% at fault on a $150,000 claim, you recover $120,000. If you are 51% or more at fault, you recover nothing. The at-fault driver's insurer will try to push your fault percentage as high as possible. How your attorney documents and defends your fault assignment directly affects how much you receive.

What is the most important evidence in a T-bone crash case?

Traffic camera and dashcam footage is decisive when it exists, but it is overwritten within 24 to 72 hours at most intersections. After footage, police reports with citations and crash diagrams are critical, followed by vehicle event data recorder data capturing pre-impact speed and braking, witness statements collected close in time to the crash, cell phone records establishing distraction, and physical evidence analyzed by an accident reconstructionist. Medical records from the day of the crash document your injuries from the outset.

What injuries are most common in side-impact crashes?

The most commonly documented T-bone injuries are traumatic brain injury, cervical and thoracic spinal injuries, rib fractures with potential lung or internal organ involvement, pelvic fractures, and arm and shoulder injuries. Soft tissue injuries such as lateral cervical strain, hip ligament tears, and knee injuries from door intrusion are also frequent and contested by insurers because they often do not appear on standard imaging. Symptoms for brain and spinal injuries frequently have delayed onset.

Does my own insurance cover me if the at-fault driver has no insurance?

Yes, if you have UM/UIM coverage. Louisiana insurers are required to offer uninsured/underinsured motorist coverage under [La. R.S. 22:1295](https://legis.la.gov/legis/Law.aspx?d=508161), and it remains on your policy unless you rejected it in writing. If the at-fault T-bone driver has no insurance or minimum coverage of $15,000 and your damages exceed that, your UM/UIM policy covers the gap up to your policy limit. Many people discover they have this coverage only after consulting an attorney. Check your declarations page or call your insurer to confirm.

What if the traffic light was broken when the T-bone crash happened?

When a traffic signal is malfunctioning or dark, Louisiana law treats the intersection as a four-way stop. All drivers must stop and yield in order of arrival. If the malfunction was known to the transportation authority and not corrected before your crash, the government body responsible for signal maintenance may share liability in addition to the at-fault driver. Documenting the malfunction requires subpoenaing signal maintenance records, outage logs, and prior complaint histories. A government liability claim against a municipal or state authority has specific procedural requirements and shorter notice deadlines, so contact an attorney quickly.

Can I file a claim if a family member died in a T-bone accident?

Yes. Louisiana law provides two separate claims. A survival action under [La. C.C. Art. 2315.1](https://legis.la.gov/legis/Law.aspx?d=109385) recovers damages the victim suffered between the crash and death. A wrongful death action under [La. C.C. Art. 2315.2](https://legis.la.gov/legis/Law.aspx?d=109386) compensates surviving family members for their own losses including loss of financial support, loss of companionship, and funeral expenses. Both claims can be filed simultaneously. The prescriptive period under [La. C.C. Art. 3493.11](https://legis.la.gov/legis/Law.aspx?d=1092220) applies.

How does Louisiana's No Pay No Play rule affect a T-bone accident claim?

Louisiana's No Pay No Play rule, La. R.S. 32:866, restricts uninsured drivers from recovering the first $15,000 in bodily injury damages and the first $25,000 in property damage, even when the other driver was entirely at fault. The rule applies regardless of fault. If you were driving without insurance at the time of your T-bone crash, these thresholds reduce your initial recovery. Coverage above those amounts is still recoverable if your damages exceed the thresholds. The rule is a penalty for driving uninsured, not a complete bar on recovery.

What happens if there are no cameras at the intersection where my T-bone crash happened?

When no camera footage exists, fault analysis relies entirely on physical evidence and witness accounts. Crash reconstruction experts analyze crush damage vectors to determine the angle and relative speeds of impact, skid mark patterns to establish where braking began and from which direction, airbag deployment data, and vehicle resting positions. Cell phone records establish whether distraction was a factor. Witness statements gathered close in time carry significant weight in the absence of footage. An accident reconstructionist's analysis can determine which driver's account is physically consistent with the evidence and which is not.

Can I still recover if I was the driver making a left turn when the T-bone happened?

Yes, but your fault percentage will likely be significant. Louisiana traffic law requires left-turning drivers to yield to oncoming traffic. If you failed to yield and caused the T-bone, you bear primary fault. However, comparative fault under [La. C.C. Art. 2323](https://legis.la.gov/legis/Law.aspx?d=109376) distributes fault as a percentage. If evidence shows the oncoming driver was speeding beyond what you could reasonably anticipate, ran a stale red light, or was distracted, their fault percentage increases and yours decreases. If your fault is 50% or less, you can still recover a reduced amount. If it is 51% or more, you recover nothing. The outcome depends directly on the evidence established for the oncoming driver's conduct.
