Suffolk County police patrolled a stretch of Bread and Cheese Hollow Road between Pulaski Road and Route 25A in Fort Salonga Thursday in response to residents' complaints about speeding trucks, many of which they believe are carrying loads over the stated 2.5-ton limit. The complaints were made after a Monday accident in which a woman was killed when a garbage truck overturned at that intersection when its brakes failed. Suffolk County Police spokesman Tim Motz said the investigation into Monday's crash is continuing. Thursday, four officers and a sergeant with the Motor Carrier Safety Unit issued several summonses for carrying unsecured fuel, driving without a license, running a stop sign, not using a signal light and not having a safety mechanism known as a brake breakaway system. The unit's primary function is to investigate crashes and weigh and conduct safety inspections of trucks and buses throughout the county. The section was started in 1984 because of the increasing number and severity of truck accidents. Joseph Blaettler, commanding officer of the Second Precinct in Huntington, said he will be working in conjunction with the Fourth Precinct in Smithtown "for further enforcement" of the area. The accident site is at border of Huntington and Smithtown. In the Monday crash, a truck owned by Islandia-based Jet Sanitation Service Corp. was driven by Robert Moore, 40, of Ridge, who said he was driving under the speed limit when he came over a crest on Pulaski Road and the brakes failed. He said he downshifted in an attempt to slow down, then made an abrupt turn to avoid cars in the intersection. He swerved onto Bread and Cheese Hollow Road and tipped over onto a Honda Civic driven by Deborah Shavalier, 56.
