Police saw a driver clip a kerb at a roundabout in Ballymoney at 1am and when they spoke to the defendant they found he was over the limit and was also possessing cannabis.
Jordan James Charles Turner (28), of Charlotte Street, Ballymoney, was spotted on May 20 this year.
The defendant had a reading of 98 microgrammes of alcohol in 100 millilitres of breath – the legal limit is 35mcgs.
A plastic bag containing six grammes of cannabis and a grinder were found.
At Coleraine Magistrates Court today the defendant pleaded guilty to charges of driving with excess alcohol in his breath; possession of a Class B drug and using a vehicle without insurance.
Defence barrister Thomas McKeever said the defendant, who had a record, made full admissions to police.
He said his client, a self-employed sub-contractor, had made a “very foolish decision” to get behind the wheel.
District Judge Liam McNally said it was not the first time the defendant was dealt with for possessing drugs and imposed a four months prison term, suspended for two years; a 15 months driving ban and a £300 fine.
