A sheriff told a driver four times over the limit near Loch Lomond he only avoided jail because of his children.
James McLevy previously admitted he was driving drunk on April 25 on the A82 at the junction with Haul Road.
He had 96mg of alcohol in 100ml of breath, more than four times the limit of 22mg in 100ml of breath.
The 40-year-old, of Polnoon Avenue in Knightswood, returned to Dumbarton Sheriff Court on June 16.
Sheriff John McElroy KC immediately noted it was his third drink driving conviction, while McLevy's own defence solicitor accepted it was a "high degree" alcohol reading.
"Is he just deciding to drive while drunk?" asked the sheriff.
The solicitor replied it was "perhaps fortunate he stopped a short distance away from where he was camping".
He said McLevy had stopped drinking since the incident and sold his car. He had previously been banned for 13 months.
The sheriff referred to his "stupidity" and said he would now be disqualified for four years.
He further imposed a community payback order with one year of social work supervision, and he must carry out 200 hours of unpaid work in that time.
The sheriff said: "Do you understand how close you are still to going to jail?
"The only reason I'm not sending you to custody is I'm required by law to consider the impact it would have on your children. You should be ashamed of yourself."
The sentence is a direct alternative to custody and his progress will be reviewed later this year.
