I would like to know the TOTAL number of trucks that travel in the
California Highway System on a typical day in 2004, not the number of
trucks that pass a particular location within the system.

Hello,


According to the Air Resources Board, an estimated 180,000 trucks
operate in California each day.

Excerpt:

?According to ARB estimates, about 180,000 big-rig trucks operate on
California roads each day emitting about 53 tons per day (tpd) of
smog-forming nitrogen oxides (NOx) and 0.73 tpd of particulate matter
(PM). About one quarter of those trucks are registered outside of
California with 90 percent of those vehicles equipped with sleeper
cabs.?

ARB: October 2005

The rule applies to all heavy-duty vehicles operating in California,
including those with out-of-state registrations. About 180,000 heavy
trucks operate in California each day, CARB estimates, of which about
25% are registered out-of-state.

?Southern California highway network carries the largest share of

and 805 carrying as many as 35,000 trucks per day.?
