A woman was more than three times over the alcohol limit when she was caught after police received a tip-off.
Police were waiting for Kerry Richards when she turned into her home road weaving about the carriageway and mounting the kerb when she stopped.
Richards, 27, of Curzon Road, St Annes, pleaded guilty to driving with excess alcohol.
A breath test showed 114 micrograms of alcohol in her body - 35 is the limit.
She was bailed for pre-sentence reports and will be sentenced at a later date.
District Judge Rod Ross sitting at Blackpool Magistrates’ Court banned her from driving in the meantime.
Mitch Sarangi, defending, said his client, who had no previous convictions, had mental health issues.
