Seatbelt defect cases don’t always start with a dramatic, obvious failure. In the real world, people commonly report behaviors like:
- The belt didn’t lock when it should after sudden braking or impact
- The belt retracted poorly, leaving slack at the moment it mattered
- The retractor or webbing appears jammed, twisted, or misrouted
- The belt deployed unexpectedly or behaved inconsistently
- Injuries suggest restraint forces were abnormal (for example, belt-positioning issues)
In Alton, those details can be especially important when crashes involve stop-and-go traffic near commercial corridors, sudden lane changes, or roadway conditions that increase unpredictability.
