NSW govt defends trucking measures

NSW Roads Minister Duncan Gay has defended the state's heavy vehicle enforcement measures after reports trucking companies continue to put dodgy vehicles on the road.

"We have a heavy vehicle inspection force in its own right in NSW - with more than 280 frontline inspectors and investigators," Mr Gay said on Tuesday.

"They carry out more than three million screenings through checking stations and more than 300,000 intercepts and detailed inspections each year.

"This is the largest and most comprehensive enforcement and compliance regime in the country."

His comments follow an ABC Four Corners report which revealed the Victorian-based fuel tanker company involved in a fatal accident in Sydney last year was still putting dilapidated trucks on the road.

Two people were killed and five injured when a Cootes Transport tanker rolled on its side, burst into flames and collided with several cars on Mona Vale Road in October.

Mr Gay said the tanker from Victorian-based Cootes did not come under the NSW regime.

"The tragedy led NSW to successfully convince the national transport and infrastructure committee known as SCOTI to undertake work to improve the maintenance regime for heavy vehicles."
