A weapons technician was banned from driving after being pulled over by police on the A17 at Brant Broughton.
Matthew Muddiman, formerly of Leeds but now of RAF Marham, admitted drink-driving after he was found to be more than twice over the drink-drive limit.
Rory Macmillan, defending, said: “It would be an understatement to say he was shocked to find the reading was 82mg. By the time he was on the intoxilyser he had not drunk alcohol for 24 hours.”
Muddiman was fined £380 and must pay £85 costs. He was banned from driving for 18 months.
