What companies operate in the Northwest only?
 

Which ones run the Northwest areas?

don't know

Crete western regional , no farther east than Denver.

Check out Haney or TWT although twt heads south to california a bunch.

This may sound odd, but maybe looking out the window of your car may help. Seriously, you can tell who does what by the frequency of their trucks passing by. Some of them may be national companies, but have regional fleets and some may be regional companies who stay to the west of the rockies and or only run the 11 western states. Also, go to a truckstop or restarea and see if you can find the free giveaway propaganda mag's that have all the recruiting ads in them....

Check out Gordon and Market Transport.

Here are some companies that I know of in Washington State:
J.W. Lund
