A T-bone, or side-impact, collision happens almost entirely at intersections, and it puts an occupant closer to the point of impact than any other crash configuration. The legal fight that follows is rarely just about who ran the light. It is just as often about whether the injuries were really caused by the crash at all.

A side-impact collision puts very little structure between an occupant and the vehicle that strikes them, which is why T-bone crashes produce a disproportionate share of serious chest, pelvic, and neck injuries relative to their frequency.
The intersection where it happened usually settles who ran the light or the stop sign, but that is only the first fight. The second, and often the harder one, is an insurer arguing that the injuries were not really from the crash: that they were already there, or that they were caused by age rather than force.
The most straightforward T-bone pattern: a driver enters an intersection against a red light or a stop sign and strikes a vehicle with the right of way. Both drivers sometimes insist the light was in their favor, which is why signal timing and any camera footage matter so much.
A driver turning left across oncoming traffic misjudges a gap and is struck broadside, or strikes an oncoming vehicle broadside. Missouri generally requires a left-turning driver to yield to oncoming traffic, and that duty does not depend on the turning driver's honest belief that the gap was large enough.
Some intersections have limited sight lines from parked vehicles, signage, or terrain, and some signal timing creates ambiguity at the changeover between phases. Where the intersection design itself contributed to a crash, a government entity's design and maintenance choices can become relevant, alongside the drivers involved.
A vehicle's front and rear are engineered with crumple zones designed to absorb energy before it reaches an occupant. A door has very little room to do the same thing, which is why side-impact crashes translate more of the collision's force directly into the people sitting closest to the point of impact.
An active grandmother was T-boned and left with permanent chronic neck pain. The insurance company's argument was not that the crash did not happen or that the impact was minor. It was that her injuries were a product of her age rather than the collision, and it offered $14,937.
The case was tried. The jury heard the age argument and returned $2.5 million.
Insurers reach for age and pre-existing degeneration constantly in intersection cases, because nearly every adult's imaging shows some wear consistent with their age. Missouri law holds a defendant responsible for aggravating a condition someone already had, and this verdict is what that principle looks like applied by a jury rather than argued in a settlement letter.
Past results do not guarantee a future outcome, and every case depends on its own facts. These are public-record results that show what trial-prepared representation can produce.

Signal-phase and approach footage is often the single clearest evidence of who had the light or the right of way, and it is also some of the fastest evidence to disappear. Request it within days, not weeks.
Where exactly each vehicle was struck helps establish the angle and sequence of the collision, which matters when both drivers describe the intersection differently.
Insurers use any prior imaging or degenerative finding to argue the crash changed nothing. A documented change in function and symptoms from before the crash to after it is what answers that argument.
An adjuster pointing to age or a pre-existing condition in an early call is making an argument, not stating a fact. In one of our T-bone cases that argument was made to justify a $14,937 offer, and a jury returned $2.5 million.
Generally, the driver who failed to yield the right of way: the one who ran a red light or stop sign, or who turned left across oncoming traffic without an adequate gap. Establishing which driver actually had the right of way often depends on signal timing, camera footage, and physical evidence at the scene rather than either driver's account alone.
This is common, and it is resolved with evidence rather than the drivers' conflicting accounts: intersection camera footage, signal timing records, the vehicles' final positions, and any independent witnesses. Reconstruction can often establish which vehicle entered the intersection first and from which direction.
A vehicle's front and rear are built with crumple zones designed to absorb impact energy before it reaches the occupants. A door provides very little of that protection, so a side-impact collision transmits more force directly to the people seated closest to the point of impact, which is why chest, pelvic, and neck injuries are common even in moderate-speed T-bone crashes.
It will try to. Missouri law holds a defendant responsible for aggravating a pre-existing condition, so a prior degenerative finding or someone's age is not a defense in itself. In one of our T-bone cases, the insurer offered $14,937 by arguing our client's injuries were caused by her age; a jury returned $2.5 million.
Not automatically. While a left-turning driver generally must yield to oncoming traffic, an oncoming driver who was speeding, ran a red light, or was otherwise violating the right of way can still bear some or all of the fault. Missouri's pure comparative fault rule means fault can be apportioned between both drivers based on the evidence.
Yes. We represented an active grandmother left with permanent chronic neck pain after a T-bone collision. The insurance company offered $14,937 and argued her injuries were caused by her age. The case was tried, and the jury returned $2.5 million.
