It will cost the owner $1295 in impoundment fees to get his vehicle back.

Mortlake police said the driver would receive a summons at a later date for exceeding the speed limit and faced a mandatory 12 months off the road.

The driver needed to make alternative arrangements to return to Melbourne.

Thursday: An experienced police officer has been left shaking his head after a Greensborough man was clocked driving at 148km/h near Mortlake this morning.

Mortlake police Senior Constable Paul McLean said the 37-year-old driver faced a minimum 12 months off the road, a hefty fine and his Toyota LandCruiser would be impounded for a month, collecting impoundment fees of $1200.

"I just don't know what we can do but persistent in trying to drive the road toll down, but clearly the message is not getting through to some motorists," he said.

An 89-year-old man has died after crashing his mobility scooter into a bench at Seymour taking the state's road toll to 183, that's 61 more than last year.

The south-west road toll stands at 10 this year compared to eight for all of 2018.

This morning the LandCruiser driver was heading west on the Hamilton Highway on the east side of Mortlake when he was detected on mobile radar at 6.27am.

"He was going to a meeting. I came over the crest of a hill and his speed was consistent for 10 seconds," Senior Constable McLean said.

"He wasn't overtaking. It was a deliberate manner of driving.

"That speed, when it was still dark at that time of the morning, is just crazy.

"It's a silly speed at any time let alone in the dark when a stay animal or wildlife could step out onto the road at any time."

The experienced police officer said driving at such a speed put all road users in danger.

"It would have been better to be 15 minutes late than 15 minutes dead," Senior Constable McLean said.

Last week a P-plater was intercepted driving at 140km/h by Lismore police on the Old Geelong Road north-east of Camperdown.

The driver was fined $620 and will be off the road for six months.

Warrnambool police are also trying to identify the owner of a white Mazda sedan that was involved in a collision with a parked car in Warrnambool's Hayley Drive on August 3.

The driver left the scene without attempting to exchange details with the owner of the damaged car or report the incident to police.

The Mazda has slimline plates and is likely to have damage to the bumper.
