Senior Constable Shane Dignan, of Horsham Highway Patrol, said he had encountered four drivers exceeding 100kmh speed limits by more than 30kmh in four days.

“And that’s just me, not taking into account the rest of the unit,” he said.

He believed a Bordertown driver, 25, he encountered while patrolling the Western Highway at Serviceton about 5.20pm on New Year’s Eve was Horsham Highway Patrol’s highest speed offender for 2013.

Police allege the man’s 2010 Holden SS ute recorded 194kmh.

“He was about five kilometres from the South Australian border, headed towards Lillimur,” Sen Const Dignan said.

The driver’s car was impounded for a month.

He will be summonsed to appear in Nhill Magistrate’s Court.

Another South Australian man, 37, was fined $722 after being clocked at 151kmh on December 30.

Police caught the driver speeding along the Western Highway, near Nhill.

“He had a passenger and a lot of gear in the car at the time,” Sen Const Dignan said.

“He was moving from Adelaide to Melbourne.”

The driver was disqualified from driving in Victoria for a year, and lost eight demerit points.

A third South Australian driver was fined $541 for doing 140kmh on the Western Highway near Dimboola about 12.25pm on December 28.

The man, 42, was disqualified from driving in Victoria for six months and lost six demerit points.

A Melbourne man, 24, lost his licence for six months and was fined $614 for clocking 145kmh on the Western Highway near Lawloit on December 27.

“Any time of the year – but particularly this time, when there is more traffic on the roads – people need to observe the speed limits and be patient,” Sen Const Dignan said.

Horsham Highway Patrol Sergeant Wayne Caddy said he believed  some drivers were beyond reasoning.

“We just can’t get through to some people,” he said.
