Police found a man slumped in a car parked across the main road through Bridge of Earn in the dead of night clutching a drained bottle of vodka after being alerted by a passer-by.
And when 29-year-old Craig Ross Morgan was later tested for alcohol at Dundee Police Station they found he was over four times the legal drink-drive limit.
The test showed Morgan, of St Catherine’s Road, Perth, had 90 microgrammes of alcohol per 100 millilitres on his breath. The legal limit in Scotland is 22 millilitres.
