State Highway Patrol Solo Unit officers have impounded an unregistered dirt bike in Healesville this afternoon.
Officers detected the bike travelling along the Maroondah Highway about 1.45pm on Monday 12 June.
They intercepted the bike and spoke to the rider, a 21-year-old man from Vermont.
It is alleged the bike was unregistered, the rider disqualified and he failed a roadside drug test.
This impound is part of Operation Regal, a state-wide high visibility road policing operation over the King's birthday long weekend.
The focus of the operation will be on excessive or inappropriate speed, impaired driving, seatbelt non-compliance, driver distraction, disobeying traffic signs, and unauthorised driving.
Operation Regal will run for four days from 12.01am Friday 9 June to 11.59pm Monday 12 June.
