A case of dumb and dumber in Donvale where two mates were allegedly caught drug driving in separate incidents.
Police were first called to Springvale Road near the intersection of Serpells Road after a car mounted a concrete island and clipped another vehicle shortly after 3:30pm on Wednesday.
Police say the Warrandyte North man, 34, returned a positive reading for drugs and called a friend to pick him up.
The Ringwood man, 36, was drug tested at the scene and also returned a positive reading.
The former is expected to be charged on summons with careless driving, unlicensed driving, unregistered motor vehicle and drug driving.
The latter is expected to be charged on summons with offences including drug driving, unaccompanied learner driver and failing to display L plates.
