Police detected 43 speeding drivers during a three-hour highway operation in the North on Friday afternoon.
Members of Northern Road Policing Services targeted speeding during the operation, with one driver caught overtaking an unmarked police vehicle while travelling at 138km/h.
The driver - who was intercepted by police - was already disqualified from driving.
He will appear in court at a later date.
Police also intercepted a P1 licence holder - with a 100km/h restriction on their licence -who was travelling at 125km/h.
The P-plater was fined $353.50 and received three demerit points.
In addition to the 43 speeding drivers, police also intercepted a driver whose vehicle registration had been expired for nine months.
Acting Sergeant Daniel Midson said the results were disappointing.
"Road safety is everyone's responsibility, and we are urging all road users to make safer choices," he said.
"Tasmania Police is committed to reducing the number of deaths and injuries on our roads, which is why we conduct a range of enforcement activities to make our roads safer for everyone."
To report dangerous driving, call police on 131 44 or Triple Zero (000) in an emergency.
