Police impounded two cars within 30 minutes while on patrol in Sunshine on Thursday morning.
About 12.40am, officers intercepted a Holden Barina on Ballarat Road.
A 28-year-old Braybrook man returned a positive preliminary oral fluid test and allegedly refused to undergo a secondary test.
Police said the driver had never held a Victorian driver’s licence and was disqualified from driving.
The man had his car impounded for 30 days and is expected to face charges.
A short time later, officers observed a Jaguar sedan allegedly swerving at 80km/h on the Western Ring Road about 1.05am.
Officers intercepted the vehicle and discovered the 28-year-old male driver, from Point Cook, had also never held a Victorian driver’s licence.
The man underwent a roadside breath test which returned a positive result.
He then allegedly refused to accompany police to a nearby police station for an evidentiary test and walked away from his own vehicle.
His car was impounded for 30 days and he is expected to be charged on summons.
