Everyone from MD should look up the " Maryland motor carrier handbook pdf " that was revised on Feb of 2012. Dot is out in full force and are writing tickets everyday all day on MD RT 32 , MD RT 108, MD RT 2, Ten Oaks Rd, MD RT 216, MD RT 1 in Jessup just to name a few places that we see them almost daily and on weekends. They have a field day with landscape trucks and trailers and from what I hear there have been no warnings only alot of tickets written. Just wanted to give everyone the heads up. They will be checking lights , saftey chains , brake away systems , the cable from the brake away to the truck , DOT numbers , Med cards, tarps , weight , insurance, fire extiguishers , flares or triangles and on an open trailer your mowers must be tied down from four points two of which must be with a chain and no more than 5 gallons of gas with out a DOT approved container.
