On Thursday, Australia’s largest ever police crackdown on heavy vehicles was rolled out across the state.

NSW Police Assistant Commissioner of Traffic and Highway Patrol Michael Corboy tells Ray Hadley over 6,000 trucks were pulled over as part of Operation Rolling Thunder.

“We had 2,000 defect notices, a lot of these were minor. Unfortunately, we had 33 major defects.”

26 drivers were busted for getting behind the wheel with methamphetamines in their system, a result AC Corboy says is unacceptable.

“The 26 is too many and it concerns me that people think they can drive heavy vehicles with drugs in their system.

“Yesterday we sent a really clear message that we’re on top of this we’re going to keep doing it.

“Don’t let your guard down because we will be doing this again and again.”
