I just tried looking up to see if I need/register a DOT # for my trucks. Only when I went to click on the "who needs one" link it was under construction, great! Those familar with whats needed........mind sharing some wisdow? I do landscape/hardscape and would be hauling such materials. At times, as needed, from VA to MD and also from VA to DC. Possibly also picking up material as needed in MD. Thanks!
