HAGERSTOWN - A tractor-trailer driver steered his big rig onto the parking lot of the state police barracks at Hagerstown yesterday afternoon, and said he was lost.

But police said he was also drunk - and found in the vehicle several six-packs of beer, and cans, pints and liter bottles of various alcoholic beverages, many of them partially empty, and others empty.

The rig, "obviously over 40 feet in length," was driven past a sign on the roadway near the barracks prohibiting vehicles of larger size, police said. The driver - unable to turn the vehicle around because of limited space - was advised to come into the building with his paperwork, and found to have "a strong odor of alcoholic beverage" in his breath, police added.

Alan Joseph Pivarnik, 36, of Fairfield, Conn., working for Swift Transportation Co. out of Oklahoma City, was given field sobriety tests in the barracks lobby and then charged with driving under the influence, failure to obey a traffic control device and consuming alcoholic beverages while operating a commercial vehicle, police said.
