Five gasoline tanker trucks were taken out of service, while police and other inspectors issued 19 summonses for a total of 43 violations, during a safety inspection checkpoint in Brentwood.
The trucks halted had a variety of safety issues, from faulty brakes to dangerous wheel-hub conditions and leaking gas and brake lines, authorities said.
The mandatory stops and inspections began Thursday at 11 p.m. and ran through 4 a.m. Friday in the Park and Ride lot at Wicks Road, police said.
They were carried out by the Suffolk County Highway Patrol Motor Carrier Safety Section, in conjunction with State Police, the state Department of Transportation, the state Environmental Conservation Police, the state Department of Taxation and Finance and the Suffolk Consumer Affairs Bureau of Weights and Measures.
Police said a total of 13 trucks were inspected during the five-hour checkpoint operation.
Fourteen of the summonses were for equipment violations, police said, while three were for environmental violations.
Three trucks were cited for tax-law violations, while two were cited for noncompliance of registration regulations.
Police said the interagency enforcement initiative is part of an ongoing effort to ensure compliance with commercial motor vehicle and hazardous material safety regulations, as well as compliance with tax laws and environmental safety concerns -- especially concerns related to fuel tankers.
In January 2010, a fatal tanker truck crash involving a truck and an auto on the eastbound Long Island Expressway occurred between exits 48 and 49, igniting a huge fireball that created a fire so intense it collapsed a road-sign stanchion.
A tractor trailer crash on the LIE between exits 68 and 69 in Yaphank in December 2012 caused a fatal 35-vehicle pileup. An investigation found the Vermont-based trucking company involved had been cited for at least 23 unsafe driving violations in the previous two years.
