T-Bone Accident in St. Louis: Your Rights After a Side-Impact Crash

Call 911 immediately after a T-bone accident. T-bone crashes produce severe injuries — the side of your vehicle absorbed the full force of the other car. Even if you feel okay initially, the impact forces in a side-impact crash can cause internal injuries that are not immediately apparent. Request emergency medical services if anyone is hurt.

In St. Louis City, SLMPD responds to intersection crashes. Call the non-emergency line at (314) 231-1212 for non-injury crashes. The police report is especially important in T-bone accidents because fault is often contested — both drivers may claim they had the green light. The officer will document traffic signal status, witness statements, vehicle positions, debris patterns, and any traffic camera systems at the intersection.

Do not move your vehicle until police document the scene, unless it is creating a safety hazard. The position of the vehicles after a T-bone crash — which side was struck, the angle of impact, where the vehicles came to rest — is critical evidence for determining who had the right of way. Take photos of the vehicle positions, intersection layout, traffic signals, and all damage before anything is moved.

The central question in every T-bone accident is: who had the right of way? This usually comes down to who ran the red light, who failed to yield at a stop sign, or who violated a right-of-way rule. Evidence that answers this question wins or loses your case.

Look for traffic cameras at the intersection. Some St. Louis intersections have red light cameras or city-operated traffic cameras that capture signal status and vehicle movements. MoDOT cameras cover highway on/off ramps where T-bone crashes are common. Nearby businesses may have security cameras that caught the crash. Dashcam footage from your vehicle or any other vehicle at the intersection is invaluable. Request or preserve this footage within 24-48 hours before it is overwritten.

Witness testimony matters enormously in T-bone cases. Drivers waiting at the intersection, pedestrians on the sidewalk, passengers in nearby vehicles, and workers at nearby businesses may have seen which vehicle had the green light. Get names and phone numbers immediately — witnesses leave and become difficult to find later. If the other driver made any statement at the scene acknowledging fault — 'I didn't see the light' or 'I thought I could make it' — write it down verbatim.

T-bone accidents typically involve one driver who had the right of way and one who violated it. Common fault scenarios include: running a red light, failing to stop at a stop sign, failing to yield when making a left turn, pulling out from a side street into oncoming traffic, and failing to yield at an uncontrolled intersection. The driver who violated the traffic signal or right-of-way rule is generally at fault.

Missouri's pure comparative fault rule (Mo. Rev. Stat. §537.765) is especially important in T-bone cases because fault is rarely clear-cut. Maybe you entered the intersection on a yellow light that turned red. Maybe you were going slightly over the speed limit when the other driver ran their stop sign. In most states, being even partially at fault could eliminate or severely reduce your recovery. In Missouri, your damages are reduced by your fault percentage but never barred entirely. If you are 20% at fault and your damages total $100,000, you recover $80,000.

Left-turn T-bone accidents are particularly common. The driver making the left turn generally must yield to oncoming traffic. However, if the oncoming driver was speeding, ran a yellow-to-red light, or was otherwise difficult to see, comparative fault may shift some responsibility. Missouri courts analyze each driver's conduct to assign fault percentages.

Side-impact crashes produce a distinct pattern of severe injuries because the door and window are the only barriers between the occupant and the striking vehicle. Common T-bone injuries include traumatic brain injuries from the head striking the window or door frame, broken ribs and sternum from the door caving inward, pelvis and hip fractures, spleen and liver lacerations from blunt abdominal force, shoulder and arm injuries on the impact side, and cervical spine injuries.

For serious T-bone crash injuries, St. Louis has Level I trauma centers at Barnes-Jewish Hospital (BJC) in the Central West End and SSM Health St. Louis University Hospital in Midtown. These facilities provide 24/7 trauma surgery, neurosurgery, and orthopedic surgery. If you are conscious and mobile at the scene, still go to the emergency room or see a doctor within 24 hours — internal injuries from side-impact forces can be life-threatening even when external symptoms are minimal.

Follow your doctor's full treatment plan. T-bone crash injuries often require surgery, extended hospitalization, physical therapy, and long-term rehabilitation. Do not skip appointments or discontinue treatment — gaps in your medical record give the insurance company ammunition to argue your injuries are not as serious as claimed.

When fault is disputed in a T-bone accident, insurance companies dig in. The other driver's insurer will likely argue that their driver had the green light or that you failed to yield. They will look for any evidence that shifts fault to you — your speed, whether you entered the intersection late, whether your view was obstructed.

Do not give a recorded statement to the other driver's insurance company without consulting an attorney. In T-bone cases with disputed fault, every word you say can be used to increase your fault percentage and reduce your recovery. Let your attorney handle communications with the opposing insurer.

If the other driver's insurance denies liability, you may need to file a claim under your own collision coverage for vehicle damage and your UM/UIM coverage for injuries (if the other driver was uninsured or underinsured). Missouri law requires UM coverage unless you rejected it in writing (Mo. Rev. Stat. §379.203). Your attorney can pursue the at-fault driver's insurer through negotiation or litigation while your own coverage addresses your immediate needs.

T-bone accidents with severe injuries — TBI, spinal injuries, pelvic fractures — can result in six- and seven-figure claims. Your compensation can include medical bills (past and future), lost wages, lost earning capacity, pain and suffering, emotional distress, loss of enjoyment of life, and property damage. In cases involving egregious conduct like running a red light at high speed, punitive damages may be available.

Missouri's 5-year statute of limitations (Mo. Rev. Stat. §516.120) applies, but do not wait. Traffic camera footage is overwritten quickly. Witnesses forget. Physical evidence at the intersection is cleaned up. An attorney can send preservation letters to the city and MoDOT to save camera footage, and can begin investigating the intersection's crash history to strengthen your case.
