Robson Jones, aged 22, was caught behind the wheel of a Ford Focus on the B4391 in Llanfyllin, Powys, on August 13. A breathalyser test found he had 78 microgrammes of alcohol in 100 millilitres of breath. The legal limit is 35mcg.
Jones, of Cefn Coch, Welshpool, pleaded guilty at Welshpool Magistrates Court to driving a motor vehicle when above the legal alcohol limit.
He was disqualified from driving for 20 months and fined £250. His road ban will be reduced by 23 weeks if he completes a safer driving course.
