Operation Shaker was a collaboration between Victoria Police, the NSW Roads and Traffic Authority, the Victorian Sheriffs Office, the Department of Sustainability and Environment and its wildlife section, the RSPCA and Customs.

The massive operation ran throughout Gippsland and was based in Rosedale.

Police said the effort was part of an interstate crackdown on heavy vehicles, ensuring trucks en-route to NSW met safety and protocol standards and checking motorists for outstanding warrants and fines.

Drivers were also tested for drugs and alcohol.

No drivers were caught driving under the influence of drugs or alcohol out of the 2000 vehicle checks conducted.

An automatic number plate recognition system vehicle was also used throughout the operation, scanning number plates to check for outstanding fines, unregistered vehicles and unlicensed drivers.

The operation derived its name from the Vehicle Inspection Trailer, on loan from the NSW RTA. A heavy vehicle drives onto the trailer, one axle at a time, and among other tests, the trailer `shakes' the vehicle to test the integrity of its suspension.

VicRoads regional manager Patricia Liew said the most common fault discovered throughout the operation was brake faults in heavy vehicles.

"VicRoads is pleased the overall condition of heavy vehicles being checked has improved since the last operation of this kind,'' she said.
