Can they use my not wearing a seatbelt against me in Texas?

The rule that changed in 2015

For forty years, Texas juries never heard the word seatbelt: the old cases reasoned that failing to buckle did not cause the crash, so it could not reduce the recovery. In 2015, the Texas Supreme Court overruled that line and held that relevant evidence of seatbelt use or nonuse, and of a plaintiff's injury-causing conduct generally, is admissible for apportioning responsibility under the proportionate-responsibility statute, reasoning that a system built to weigh every cause of the injuries could no longer ignore one. The seatbelt defense is therefore real, and anyone telling you otherwise is practicing last century's law.

What the defense actually has to prove

Admissible is not automatic. The nonuse must be proven, and, decisively, it must be causally connected to the injuries: the defense needs reliable expert testimony, typically biomechanical, that wearing the belt would have prevented or reduced the specific harm claimed, testimony that must survive the same reliability gatekeeping as any science in a Texas courtroom. That burden has edges worth pressing, a belt does nothing for the arm shattered against the door, the injuries from intrusion into the occupant's space, or countless harms a buckle never touches, and a generic expert opining that belts are good is not proof that this belt would have changed this spine. Even where the argument lands, it lands as percentage points in the comparative-fault machinery, reducing recovery below fifty-one percent and barring it only above, with the underlying negligence of the driver who caused the crash still carrying the heaviest weight in the room.

The flip side: proving you were belted

The decision cuts both ways, and belted plaintiffs should now prove it affirmatively rather than assume it: the vehicle's event data recorder logs belt status at impact, the bruising a belt leaves across chest and hip is medicine's receipt, and the responding officer's notation matters, all reasons the preservation letter on the vehicle, described on the black-box page, went from good practice to essential in every serious crash. A plaintiff who can open with data showing the belt latched has taken the defense's favorite new toy off the table before it is unwrapped.

If the adjuster has already mentioned your seatbelt

Then the file is being built for an apportionment fight, and yours should be too. Silver Key Law works both sides of the belt question, the data and the biomechanics, and the consultation is free.
