Is testing diesel trucks pre-2008 necessary? Many of those trucks
are not equipped with a catalytic converters, none of them have
Diesel Particulate Filters (DPF), each only being equipped with the
equipment required only for that year. By doing the snap tests, all
that is accomplished is to see if they are blowing too much smoke,
but it does nothing to reduce SMOG levels from those trucks...and
that is only during the testing at a SMOG Station. 

Because of the newer emissions requirements, only trucks 2008 and
newer are the only trucks equipped to actually reduce SMOG output
from the tailpipe.

As an owner of a pre-2008 Diesel-powered pickup truck, all this
snap testing does it take money out of my pocket that I could use
for other things, especially in this economy.

So...what good does it really do to check pre-2008 trucks?
