Senior Sergeant Parker of Oatlands Police said that although it was pleasing to not detect any drivers driving under the influence of alcohol, it was concerning that four drivers were detected driving with illicit drugs in their systems.

Four other people are to be summonsed for offences under the Firearms Act with the Police Dog Olsen assisting in the detections.

Three people have also been summonsed for possessing cannabis after detections by Police Dog Aggie.

Defect orders were issued to 15 motorists for vehicle defects.

"Motorists are reminded to do the right thing on our roads and avoid the 'fatal five' contributing factors to fatalities and serious injuries on our roads; speeding, drink and drug driving, not wearing seatbelts, fatigue - and something we're seeing more and more, which is inattention and distraction," Senior Sergeant Parker said.

"There are fines for disobeying the road rules, but the real penalty could be killing or seriously injuring yourself or someone else.

"Remember we could be anywhere, anytime and in any vehicle, so please do the right thing by everyone on our roads."
