On-Road Heavy-Duty Vehicle Program
Emissions from on-road heavy-duty vehicles are major contributors to poor air
quality in California. In particular, diesel vehicles produce
emissions in amounts highly disproportionate to the total population of
these vehicles. The problem is complicated by the large number of
heavy-duty vehicles, like line haul trucks, registered in
other states that travel on California's highways and roads, while
bringing goods and commerce into and out of our state. The Air
Resources Board is working closely with the
U.S. Environmental Protection Agency, engine and vehicle
manufacturers, and other interested parties to address this issue
and reduce heavy-duty vehicle emissions in California. Although
this program targets both diesel-cycle and otto-cycle engines, more
recent attention has been focused on diesel engines due to the
identification of diesel PM as a known carcinogen.
