(LAPORTE COUNTY, INDIANA) - Truck drivers are apparently resorting to siphoning diesel fuel from other semis to save on the high cost of filling up.

According to La Porte County Police, a truck driver was parked with other semis on September 29  in the truck stop area of Gallops Marathon at U.S. 20 and Indiana 39.

The driver said he was getting some rest and woke up during the early morning hours to the sound of another semi-truck pulling a flatbed trailer parking beside him, according to police. He looked out a window, and the driver who had just pulled up waved at him.

According to police, the driver who had just arrived left about one hour later.

The driver trying to go back to sleep, later noticed his diesel fuel gauge had gone from a quarter tank to near empty after starting his engine. He estimated that 15 gallons of diesel fuel had been stolen from his tank.
