An arcade attendant was over the alcohol limit when he gave rowing relatives a lift home.
Daniel Rowlands got behind the wheel because he wanted to get the relatives out of his address because their behaviour was upsetting his children.
Rowlands, 26, of June Avenue, Marton, pleaded guilty to driving with excess alcohol.
Adrian Hollamby, prosecuting, said Rowlands was driving a Ford Fiesta on October 9, about 5am, when he pulled in front of a police car on Waterloo Road.
A breath test showed 58 microgrammes of alcohol in his body – 35 is the limit.
Jessica Partington, defending, said Rowlands brother-in-law and sister-in-law were at his home and were arguing.
He was disqualified from driving for 12 months, fined £300 with £85 costs and ordered to pay a £150 court charge.
