A P2 probationary licenced driver has lost his licence and had his car impounded after blowing more than four times the legal limit in Maddingley on Friday 23 January.
Police were called to reports of a silver MG hatch driving erratically on the Western Freeway in Melton South about 9.40pm.
Officers intercepted the vehicle a short time later and spoke with the driver on Stonehill Drive in Maddingley.
The 23-year-old driver returned a positive preliminary breath test and was taken to a police station where he returned an alleged evidentiary reading of .213.
The man's licence was immediately suspended for a period of 12 months and he is expected to be charged on summons with several traffic offences.
His vehicle was also impounded for 30 days at a cost $1,175.
The impound forms part of Operation Amity, a statewide road policing operation conducted over the Australia Day long weekend.
Police will be highly visible and enforcing in an effort to reduce road trauma, targeting impaired driving, speed, fatigue and distraction offences.
The operation commenced on Friday 23 January and runs until 11:59pm on Monday 26 January.
