Aaaaannnd we have ourselves a winnnaaahhh!
OTR trucks in CA must be 2011 or newer.
Owner/Operators are banned in CA.
In 2034 OTR trucks will be all electric; no others will be Registered by the DMV.
So much for any incentive to buy a new tractor.
Trucks must be Clean Idle certified annually.
Not that they are actually allowed to idle; trucks waiting in one spot for longer than a few minutes MUST shut down.
This and other related crap is now an Interstate Commerce issue, which is squarely in the Federal domain.
and there are NOT enough of them!!
(At least the port areas have cleaner air to breathe.)
