Officers from State Highway Patrol got more than they bargained for following an intercept in Rye last night.

Members observed a Honda Civic driving erratically along the Mornington Peninsula Highway about 9pm.

It Is alleged that the driver was using a mobile phone, travelling at 137km/h in a 100km/h zone and swerving in and out of traffic.

Police intercepted the car and spoke to the driver, a 17-year-old boy from Glen Waverley.

He underwent a roadside drug test which returned a positive result.

The boy has been interviewed for drug driving, speed dangerous, learner driver fail to have qualified driver, fail to display “L” plates, use mobile phone whilst driving and other traffic offences.

He and his 15-year-old friend, who was also in the car at the time, have a lot of explaining to do as his mother was unaware that they were in the car.

This intercept forms part of Operation Roadwise, a state-wide focus on keeping our community safe on the roads during the Christmas and New Year period.

The 24-day operation aims to reduce road trauma, including injuries and the number of lives lost on our roads.

During the festive period, motorists can expect to be breath tested, drug tested, and have their vehicles scanned and speed-checked by police to ensure everyone returns home to their loved ones safely this Christmas and New Year.

Operation Roadwise involves all available personnel including local road policing units, general duties, other operational policing units and centralised resources from Road Policing Command.

The operation runs from 12.01am Friday 13 December to 11.59pm Sunday 5 January.
