What regions and classes of vehicles are covered? The report covers the United States, Canada and Mexico and includes Class 5 through Class 8 trucks and trailers.

Are macro‑economic indicators included? Yes. Each edition includes a summary of economic conditions—GDP, industrial production, housing starts, freight activity—and their expected impact on equipment demand.

How do trailer and power‑unit forecasts interact? The report analyses both tractor and trailer demand; because tractors and trailers are deployed in ratio, we model them separately and monitor order activity appropriately. If Class 8 tractors orders are strong, that likely means trailer orders will be softer as the capital for equipment purchases is tied up in tractor sales, limiting trailer sales. Understanding the balance in the market movement is critical for forecasting production.

Does the forecast account for regulatory changes (e.g., emissions rules, phase‑in of battery‑electric trucks)? Yes. We incorporate known regulations such as greenhouse‑gas (GHG) phase 3/4 rules, California’s Advanced Clean Fleets regulations and incentives like tax credits to estimate timing and adoption of alternative powertrains.
