Police and RMS staff focused on the O’Brien Transport headquarters in Albury on Thursday and also attended the company’s depots in Melbourne and Sydney.

The business was targeted following a serious crash involving an O’Brien truck at Sutton Forest on June 1 where a driver allegedly tested positive to drugs and was found with drugs in his vehicle.

A truck driver in another vehicle was taken to hospital with serious spinal injuries and face lacerations after the crash, and remains in a serious but stable condition.

The crackdown focused on O’Brien, but also looked at drivers and vehicles from other companies.

The two Albury drivers who tested positive to drugs — one a truck driver, the other a car driver — did not work for O’Brien.

The blitz, which is part of Operation Austrans, had found 45 truck defects, including 10 major defects up until yesterday.

Forty-eight trucks and 18 trailers were inspected, two trucks were found to be non-compliant with speed limiter regulations and three log book offences were detected.

Officers had also conducted 14 random alcohol and drug tests.

O’Brien service and compliance manager Brian Moylan said the business was looking into the defects.

“We’re working through a number of defects but the fleet is still operating,” he said.

“Overall it was a fantastic health check for us.”

Assistant Commissioner John Hartley said truck companies needed to comply with all regulations and road rules.

“It is unacceptable that truck drivers and truck companies take risks that put all road users in danger,” he said.

RMS safety and compliance director Peter Wells said the operation had continued yesterday.
