Investigators report that a 62-year-old Marietta man, with a 56-year-old Marietta woman as a passenger, was operating a black 2008 Harley Davidson Ultra Classic Motorcycle north on Mack Dobbs Road.

At the same time, a gray 2007 International 7000 dump truck, operated by a 59-year-old Adairsville man, was traveling south on Mack Dobbs Road.

The public information release describes the ensuing crash as follows:

The International truck crossed the solid painted double yellow lines and collided with the Harley Davidson, causing it to veer northward and come to an uncontrolled stop on the vegetative shoulder. The International truck continued southbound in the northbound lanes until it struck a raised concrete curb and stopped in a wooded area.
