A police spokesman said Warrnambool highway patrol unit members seized the grey Holden sedan after a 54-year-old Terang woman refused to undergo a preliminary oral fluid test at a mobile testing site on October 31.

"The driver of a motor vehicle is required to undergo an alcohol breath test and/or an oral fluid test if required by a member of the police force," he said.

"Penalties for refusing can include loss of licence, a fine, vehicle impound and imprisonment."

The impoundment of a vehicle usually attracts towing and storage fees of about $1200.

Camperdown police have impounded a red Ford sedan after the driver was caught driving without a valid licence.

"It is each driver's responsibility to ensure that they have a valid licence prior to driving," a spokesman said.

"It is also your responsibility to ensure that VicRoads have your most current name and address details.

"You can renew you licence, update your details or request a licence verification letter at the VicRoads webiste."

Police are also seeking information from the public to locate a 2009 Honda CB400 motorbike last seen in Warrnambool on September 21.

Anyone with information about the motorbike is requested to contact Senior Constable Rebecca Wills at the Warrnambool police station on 5560 1333.

The bike has distinctive gold rims and a sticker that says "Cops don't like this" on it.
