David Wayne Collins, 63, was driving a Ford Falcon along Wingewarra Street when he was stopped by police at a stationary breath test, about 3.40pm on March 25.

According to police, while they were speaking to him they could smell alcohol on his breath.

Collins admitted to drinking three cans of Iron Jack Red at home since 1pm, and a positive breath test revealed a reading of 0.081.

In Dubbo Local Court on Wednesday, Collins pleaded guilty to mid-range drink-driving.

Defence lawyer Carmen McKay said Collins had been driving to work to ask for time off, after his wife was diagnosed with cervical cancer, when he was pulled over by police.

However the court heard Collins had been before the court for four other drink-driving offences over the years.

"I have explained to him the predicament he will find himself if he continues to drive in this manner," Ms McKay said.

Magistrate Gary Wilson said Collins would normally be afforded some form of leniency as he was 0.01 into the mid-range, however this time would not, as it was his fifth drink-driving offence.

"If you continue to drive in this fashion, you'll end up in prison," he said.

Magistrate Wilson convicted and sentenced Collins to an 18-month community corrections order.

He was also disqualified from driving for nine months, fined $500 and ordered to install an interlock device for 24 months.
