Ivars Vilks claimed he was not the driver of a car involved in a minor accident until police showed the key in his pocket fitted the car.
Vilks was found near the accident on the A134 at Ingham but told officers ‘I no drive’.
But on Monday at Bury St Edmunds Magistrates court he admitted his third drink driving offence since August 2011, driving while disqualified, driving without insurance and breach of a suspended sentence.
Nikki Miller, prosecuting, said a car on the A134 last Saturday was struck by Suzuki Grand Vitara.
When the driver went to talk to the Suzuki driver, he tried to drive off and had slurred speech. When police arrived ,Vilks, 45, of Mortimer Road, Bury St Edmunds, had left the car. A police helicopter found him in fields nearby.
A breath test showed he had 85 microgrammes of alcohol in 100 millilitres of breath, so was 50 over the limit.
David Stewart, defending, said Vilks had been off work with a leg injury for two years but was now working for Greene King and attending West Suffolk College. He said a previous sentence had included a requirement for alcohol dependency treatment.
Vilks was sentenced to eight weeks jail for driving with excess alcohol with eight weeks concurrent for driving while disqualified. The court activated 11 weeks of the suspended sentence to run consecutively. There was no separate penalty for driving without insurance.
