Union calls on Scott's transport CEO to stand down

Transport Workers Union (TWU) national secretary Tony Sheldon has called for the CEO of Scott's Transport to step down.

"I believe it would be appropriate for the CEO of Scott's Transport, Lee Windsor, to be stood down without pay until a full and thorough investigation has been completed," he said in a statement.

Mr Sheldon said the police work highlighted the pressures major retailers put on the trucking industry.

"Until such time as we address the core issues in the industry, dangerous behaviour will continue to be encouraged," he said.

"Coles and other major retailers control 32 per cent of the entire freight movement in the country.

"Their economic power allows them to demand ever more from drivers and transport companies."

Investigation launched

New South Wales Police launched an investigation into Scott's Transport Industries on Wednesday after one of its drivers was clocked travelling at 142km/h on the Hume Highway at Mittagong.

Since the blitz began, 60 vehicles have been pinpointed for inspection and 32 have been pulled over.

Out of them, 25 have been hit with defect notices, six have had their speed limiters tampered with and there have been 15 fatigue-related offences.

NSW police have since charged a driver,who was also allegedly high on drugs, during a swoop on major South Australian company Scott's Transport Industries.

The swoop follows a crackdown on Sydney's Lennons Transport Services earlier this year.

Police discovered eight tampered trucks, including seven that had been modified to exceed the 100km/h mandatory limit.

SA Police defect trucks in northern suburbs.

South Australian Police have also begun investigations into the deliberate tampering of speed limiters on trucks.

On Wednesday night, Officers from the Heavy Vehicle Enforcement Section defected five prime movers at a depot in Adelaide's northern suburbs, belonging to a South Australian based transport company.
