Dubbed Operation Four Ways, Victorian Police in Prahran cracked down on phone usage with motorists.
Between 9am and 3pm yesterday on Chapel Street, police targeted distracted drivers "in order to protect vulnerable road users including pedestrians and cyclists."
According to the police statement, 80 drivers committed 92 offences in the six-hour period.
"85 penalty notices were issued and 42 of them were for using a mobile phone," it reads.
"The remainder of the offences were failing to wear a seatbelt, driving an unregistered motor vehicle, performing illegal U-turns and motorcycles riding in the bicycle lane."
“The operation saw the 12 members with little time to rest, as driver after driver flouted the road rules on one of the areas busiest streets, with a high mix of bicycles and pedestrians," said Senior Constable Nick Brennan.
“It is very disappointing to see such widespread use of mobile phones by drivers despite the education and advertising used to deliver the message that distraction kills.”'
Motorists caught using mobile phones can be hit with an on the spot fine of $466 and incur four demerit points.
