Based in the metropolitan Atlanta area, Colonial Cartage has been providing direct food-grade dry and refrigerated truckload, LTL and pool distribution (bulk breakdown, order assembly and shuttle) service to Georgia, Alabama, Tennessee and north Florida for almost 40 years. The company's philosophy is to keep tractors for around ten years, but including new purchases they made in 2005 and 2006, the average power unit in their fleet is only three years old. Their next purchase will probably be in late 2009 or early 2010. Colonial Cartage tractors are also electronically limited to a maximum road speed of 65 MPH and lowering that limit to 62 MPH is now being considered. The previous road speed limit for company vehicles was 68 MPH and the drop to 65 MPH brought a 4/10-MPG savings. Another factor in realizing improved fuel economy at Colonial Cartage has been the fleet's participation in the US Environmental Agency's SmartWay Transport Partnership.
