Paccar also said it would lay off an unspecified number of workers at its assembly plant in Washington state.
Paccar said the moves are being made in anticipation of significantly lower orders for new trucks in 2007. New EPA engine regulations, which kick in as of Jan. 1, created a heavy pre-buy and used truck purchase market this year. As a result, sales of new Class 8 tractors are expected to drop sharply at least through the first half of 2007.
