A teacher was almost three times over the alcohol limit when she drove down the fast lane on the wrong side of two motorways.
Stefanie Janikiewicz drove along the M6 and M55 motorways in Lancashire for seven miles unaware she was on the wrong side.
Alarmed members of the public alerted police and a patrol stopped the teacher head-on just outside Blackpool.
Janikiewicz, 25, of Dawpool Farm, Station Road, Thurstaston, Wirral, pleaded guilty to dangerous driving and driving with excess alcohol.
She was bailed to appear at Preston Crown Court on July 4 for sentence by Blackpool magistrates.
Martine Connah, prosecuting, said police began receiving calls a car was driving the wrong way along the M55 on Sunday May 13 at 12.15am.
A police patrol put on its blue lights and stopped the defendant’s Nissan Micra head-on in the fast lane.
She appeared dazed, confused and drunk and did not know she was driving on the wrong side of the motorway until a police officer told her.
A breath test showed 97 micrograms of alcohol in her body - 35 is the limit.
Janikiewicz told police she had drunk cocktails on the train back to Manchester then had wine with a meal.
Gwyn Lewis, defending, said his client, who had no previous convictions, had been seeing a counsellor since her relationship broke down.
