Per Wikipedia, looks like the government classifies SUV’s as light trucks and they’re listed as light trucks in industry production statistics as well.
Government regulations
In the United States, many government regulations simply have categories for "off-highway vehicles" which are loosely defined and often result in SUVs (along with pick-up trucks and
minivans) being classified as
light trucks.
[3][15] For example,
Corporate Average Fuel Economy (CAFE) regulations previously included "permit greater cargo-carrying capacity than passenger carrying volume" in the definition for trucks, resulting in SUVs being classified as light trucks.
[16]
This classification as trucks allowed SUVs to be regulated less strictly than passenger cars under the
Energy Policy and Conservation Act for fuel economy, and the
Clean Air Act for emissions.
[17]However, from 2004 onwards, the
United States Environmental Protection Agency (EPA) began to hold sport utility vehicles to the same tailpipe emissions standards as cars.
[18] In 2011, the CAFE regulations were changed to classify small, two-wheel drive SUVs as passenger cars.
[19]
However, the licensing and traffic enforcement regulations in the United States vary from state to state, and an SUV may be classified as a car in some states but as a truck in others.
[20] For industry production statistics, SUVs are counted in the light truck product segment.
