A tip-off put police on the trail of a drink-driver.
James Booth, 38, of Thornton Hall Mews, Skippool Road, Thornton, pleaded guilty to driving with excess alcohol.
Jim Mowbray, prosecuting, said police received information about a VW Golf being driven in Blackpool town centre on July 3 at 5.10am.
Minutes later, a patrol spotted Booth driving the car on Dickson Road. He was in the wrong lane going straight ahead.
A breath test showed 42 micrograms of alcohol – 35 is the limit.
Booth, who had no previous convictions, said he had gone into town to meet friends. He said he had stopped drinking about 11pm.
He was disqualified from driving for 12 months and fined £120 with £85 costs by magistrates.
