Of the 2153 vehicles checked over Friday and Saturday, three drivers will face court over criminal driving offences.

There were six infringement notices issued and over 10 defects identified, which included unlicensed and unregistered vehicles.

Just over 900 breath tests were conducted but no drink drivers were detected.

Of the 14 drug tests carried out, two drivers returned a positive result.

"Overall it was a successful operation, everyone was pleased with how it went and there will be further operations in the future," Portland Sergeant Andrew Dunlop said.

"Three people will appear in court on summons at a later date over the criminal driving offences.

"Of the 10 defects identified, most of them were tyres which is a timely reminder to drivers coming up to winter to check your tyres and replace them if necessary."

The cloud-linked ANPR technology can detect motorists driving unregistered or stolen vehicles, as well as flag drivers and vehicles previously involved in speeding and other traffic violations.

"Police can scan more vehicles with the technology by driving down the street than they could in a whole shift," Sergeant Dunlop said.

The operation was carried out by Portland Highway Patrol and Portland Uniform.
