Police have been left stunned by driver behaviour after a busy start to Operation Arid in the south-west.
South west police road safety manager Senior Sergeant Chris Asenjo said Southern Grampians district police had been particularly productive with a string of speeding drivers detected in the past couple of days.
He said on Saturday in one shift officers clocked a P-plater at 140km/h, another vehicle with two children in the back seat at 131km/h and other drivers at 126, 122, 117, 116, 115, 114 and 111km/h.
Most were detected east of Hamilton on the Glenelg Highway.
In addition Senior Sergeant Asenjo said a disqualified driver has had his car impounded after being caught travelling at 125km/h on the Camperdown-Lismore Road.
"We have seen some disgraceful driver behaviour during the past couple of days across the region," he said.
"Driving at such high speeds is just a collision waiting to happen. Drivers are not getting the message and as a result we are seeing is people die on our roads."
Senior Sergeant Asenjo said police members would saturate south-west roads on Monday afternoon as people made their way home at the end of the long weekend.
"We just want everyone to get home safe. It's nothing more complex than that. We're not interested in raising revenue," he said.
At around midnight Saturday, a 21-year-old Hawthorn East man pulled out of a car park in Hamilton's Market Place.
He then parked his car and walked away 20 metres, but the P-plater was requested to do a breath test and recorded a reading of .02.
The driver will now be walking for the next three months.
Early Monday morning an interstate driver was detected on the Princes Highway at Balworra at 110km/h in a 80 zone.
He also blew a reading of .077, was fined almost $1000 and his licence will be suspended for six months.
