Two police officers on patrol in the Bude area on February 15 saw the Transit van come out of a car park and go the wrong way up a one-way street. They found the vehicle in a layby and Jones was arrested on suspicion of drink-driving.
His ban will be reduced by 18 weeks if he completes a rehabilitation course. Jones, 23, had admitted failing to provide a specimen and driving his works' van without a licence. The court was told that his driving licence had been revoked until he passes a test.
He made four attempts to give a breath sample at the police station but failed to blow enough each time. Computer checks showed his licence had been revoked by DVLA after he had been convicted of careless driving by a North Wales court.
Jones, of Craig y Don, Amlwch, Gwynedd, told the court that he had tried his best to give a sample and had believed that he was entitled to drive as he had not received any notification of the revocation. He had now lost his job as a result of the offence being committed in his works' van.
Probation officer Tony Ciocci said that Jones had been working in Cornwall. On the night of the offence he could not find a bed and breakfast and planned to sleep in his van. He had a couple of pints early on and then bought a pizza.
