Sergeant Vicki Phillips said that was not a trend police wanted to continue and unfortunately there were still people willing to take the risk of drinking and driving.

"Three in three night. We're not happy," she said.

"There was police Operation Arid in place over the long weekend, but even when there's not an operation police members are on patrol and will intercept drivers and conduct preliminary breath tests."

At 4.40am Monday morning a 49-year-old man was pulled over after being detected speeding along the Princes Highway at Bolwarra.

He was clocked at 110km/h in an 80 zone and had an alcohol reading of .077.

He received fines of almost $1000 and will be suspended from driving for six months.

On Monday at 11.55pm a 24-year-old woman was pulled over in Portland and tested positive to drink driving.

The circumstances of her drink driving were so serious that she will be summoned to appear in the Portland Magistrates Court on a date to be fixed.

And a 45-year-old man is also heading to Portland court after being intercepted drink driving at 11.30pm on Tuesday.

"Clearly this is a trend and we will be focusing resources on drink driving. It's just too dangerous for all road users," Sergeant Phillips said.
