Fourteen drivers copped fines and licence suspensions during a weekend police operation on the Frankford Highway.
The crackdown, held on Saturday, saw police target speeding motorists at Exeter.
Acting Inspector Martin Parker said all were caught in just one hour.
“Among them, a motorcyclist was clocked at 128km/h in a 60km/h zone, resulting in an immediate 4-month disqualification, a $1161.50 fine and 6 demerit points,” he said.
“Additionally, a P-plater was caught travelling at 101km/h in a 60 zone, receiving an immediate 3-month disqualification, an $858.50 fine and 6 demerit points.”
He said occupant of a speeding vehicle was also found not wearing a seatbelt.
The result prompted a further drug and alcohol testing operation on Monday, which caught one person drug driving and another driving an unregistered vehicle.
“We are concerned with the amount of dangerous driving detected over the past few days, as this shows there are multiple drivers committing traffic offences and putting other road users and themselves at risk,” Parker said.
“Police will continue to target unsafe and risky driving behaviour to ensure the safety of all road users and we ask our community members to help us do this by letting us know if they witness dangerous driving on our roads.”
