Diesel Truck Industry Statistics

With 48% of 2024 U.S. diesel truck orders going to EPA SmartWay certified fleets, and over 90% of new on road diesel trucks now equipped with diesel particulate filters, this page connects emissions rules, operating tech, and real fleet adoption. You will also see how fuel prices, idling costs, and safety outcomes stack up against the scale of road freight, including road’s 30% share of global freight movement.

Diesel truck statistics are painting a picture that is at once tightening and accelerating, with 76,000 commercial vehicle crashes still being reported in 2022 while U.S. fleets lean harder on EPA SmartWay certified operations at 48% adoption for the 2024 model-year. At the same time, road freight moves a huge share of global activity, yet diesel truck fuel and emissions performance hinges on details like DPF-equipped compliance, predictive analytics, and idling reductions. This post pulls together those competing signals into one dataset, so you can see where operational gains are really showing up.
