SOUTH Australian police have tested 106 heavy vehicles for roadworthiness during an operation on the Sturt Hwy, Daveyston.
With assistance from vehicle inspectors from Department for Planning, Transport and Infrastructure, Barossa Local Service Area police ran the operation last Friday.
Using the ROSAT, an on-road safety audit trailer also known as the Shaker, heavy vehicles were randomly selected to undertake safety inspections.
The ROSAT offers the same standard of checking suspension, brakes and steering of heavy vehicles as a well-equipped vehicle inspection station and is welcomed by many truck drivers.
Brevet Sergeant Bryan Dicker of Barossa Local Service Area says most drivers are cooperative.
"Faults can sometimes be difficult to pick up by drivers and operators, and the ROSAT Shaker offers a professional, free check on key safety aspects of the vehicle," he said.
"Of the 106 heavy vehicles tested on the ROSAT Shaker, 32 failed inspection and were issued with a major defect. This requires them to be cleared at a Vehicle Inspection Station."
Defects were issued mainly due to brake failures. In one case, a steering wheel fell apart when being examined.
"One vehicle was grounded and towed from the scene."
"Ten were issued with infringement notices"
The high level of defects is concerning, but police have noticed an area of improvement.
"Load security is definitely improving. This may be due to changes where responsibility for securing loads is shared between those who load the vehicle as well as the driver.
"We will continue to run several operations of this type a year, so heavy vehicle drivers are generally on notice that their trucks are likely to be inspected."
