Freightliner Trucks is a manufacturer of heavy duty trucks, chassis and semi-trailer trucks.

The company was founded as Freightliner LLC in 1942 and is now a division of Daimler Trucks North America LLC, which is in turn a subsidiary of Daimler AG.

The company is known mainly for the heavy duty class 8 diesel trucks that it produces, as well as class 5-7 trucks.

As of 2005 Freightliner is the largest manufacturer of heavy duty trucks in North America with annual earnings of over $32 billion (2006 est.) and over 22,000 employees (including Detroit Diesel).

Due to the fact that Freightliner LLC is a wholly owned subsidiary of Daimler, a non American corporation, it is not included in Fortune 500 rankings.

Were it to be ranked however it would list as the 125th largest company in America based on the criterion used in said ranking.
