A 30-year-old woman has blown almost seven times the legal alcohol limit after allegedly rear-ending a car in Cockatoo last night.
An off-duty police officer reported seeing a vehicle driving erratically shortly before 5.30pm.
Mount Evelyn police tracked the driver to her Launching Place home where she returned a positive breath test.
She also admitted to being involved in a collision with another vehicle on Paternoster Road shortly after 5pm – she exchanged details with the other driver before heading home.
Police took the woman to Lilydale Police Station for an evidentiary breath test where she returned a reading of .345.
Her licence was immediately suspended and she will be charged via summons in relation to drink driving and other traffic-related offences.
