The Deadliest Trucking Corridors in America

Truck crashes aren't spread evenly across the map — they concentrate on the freight lanes. I-45 between Houston and Dallas has repeatedly ranked among the deadliest highways per mile in the country. I-35 carries the busiest truck border crossing in the US north from Laredo. I-80 crosses Wyoming crosswinds that flip trailers, and I-5's Central Valley fog has caused some of the largest pileups in American history. Each corridor below explains why crashes cluster there — freight volume, terrain, weather, and schedule pressure — and links to the state pages that govern your deadline.

Corridor context matters legally as well as statistically: it identifies the kinds of carriers involved (port drayage, border freight, oilfield hauling), the federal rules most likely violated, and the evidence worth preserving first. Wherever the crash happened, the deadline comes from that state's law — find yours on the state pages.
