Vic blitz nabs drink-driver 4 times over

A Victorian woman has been caught driving more than four times over the legal blood-alcohol limit.

The 34-year-old Wyndham Vale woman was one of many caught despite police warning they would be out in force over the Queen's Birthday long weekend.

The woman was driving an unregistered car when she was pulled over by police in Quandong about 3.10pm on Saturday.

It's alleged she returned a blood-alcohol reading of 0.264.

She has had her car impounded and is expected to be charged on summons for traffic related offences.

Earlier in the day police say they clocked a man travelling 171km/h in a 100km zone in Pakenham.

He was also driving without a licence and wanted on outstanding warrants.
