Striking truck drivers created minor disruptions in Maryland Friday and yesterday, moving in a slow motion convoy around the Baltimore beltway yesterday.

According to Maryland state police, about 100 trucks circled Baltimore on Rte. 695 from about 11 a.m. to 3 p.m. The trucks, which stayed in the center lane of the beltway, created only minor trafic slowdowns, police said.

On Friday, several truck drivers blocked fuel pumps at a service station on Rte. 40 near Cumberland. State troopers were called to the scene about 9:40 a.m., but no charges were filed. Later Friday morning two drivers for Hahn's Transportation of New Market, Md., were forced by striking truckers to detach their truck trailers and leave them at the same service station. The drivers later returned and removed their trailers without incident, police said.

A driver for Smith Transfer Co. of Baltimore was stopped on the Baltimore Beltway late Friday afternoon by four men in two tractor-trailer trucks, driven to a remote area and robbed of $22. State police said the incident may not have been related to the strike. According to state police, Henry Lee Douglas was forced to the shoulder of the beltway by two trucks. Two men, one from each of the trucks and one bearing a sawed-off shotgun, clumbed in the truck with Douglas, blindfolded him and drove him to Pasadena, Md., where he was robbed, police said. The robbers then fled in the two trucks, which had followed, according to police.
