A P-plate driver had his car impounded after a passenger was found in the boot of his car during a routine intercept in McCrae overnight on Friday 20 January.
Somerville Highway Patrol officers set up a breath test site on the Mornington Peninsula Freeway McCrae off-ramp when a Subaru Impreza hatch with red p-plates and four passengers drove through about 5.50pm.
Officers spoke to the driver who was the holder of a P1 licence who can only have a one passenger in the car.
Police made further checks and opened the boot, finding a fifth passenger curled up in the cargo area under the privacy shade.
The driver, an 18-year-old Narre Warren man, had his car immediately impounded for 30 days at a cost of $1200.
He is expected to be charged on summons with driving with a passenger in part of the vehicle designed primarily for the carriage of goods, drive without rear p-plate and P1 Probationary driver drive with more than one peer passenger.
His stowaway passenger was also fined $370.
