Since 2015 a fourteen‑mile stretch of Interstate 10 through New Orleans East has seen truck‑car collisions multiply from 69 in 2004 to nearly three times that by 2017. Most crashes involve large tractor‑trailers rear‑ending passenger cars, often injuring several occupants. The surge appears isolated—no lighting flaws or steep grades explain the anomaly.

Investigators note a recurring pattern: a car sideswipes the back of a semi as the driver changes lanes, then the trailer pushes the vehicle into the shoulder. LSU professor Helmut Schneider calculated the probability of so many multi‑passenger crashes in one corridor as one in 750 trillion. A recent lawsuit cites two victims who required spinal surgery after such an impact.

Accident reconstructionist Wayne Winkler, a former state trooper, found the I‑10 incidents mirror dozens of similar lane‑change side‑swipes across New Orleans East. While Europe mandates side barriers on trailers, U.S. carriers argue cost prevents adoption. The pattern underscores that current safety hardware—rear‑impact guards alone—fails to stop frequent, high‑severity crashes on this corridor.

Federal regulations already limit drivers to eleven hours behind the wheel, and modern rigs employ computer‑assisted braking akin to aircraft systems. Yet the New Orleans East data show that procedural safeguards alone cannot compensate for design gaps. Implementing side‑impact barriers on trailers would directly address the recurring lane‑change collisions highlighted by the investigation.
