Simon Gregson, who plays Steve McDonald in the soap, was stopped when a police officer saw his Jaguar going the wrong way down a one-way street in Cheshire.
He gave a positive roadside test and two further tests were positive.
Mr Gregson, 31, of Wilmslow, who denied drink-driving, was bailed for sentencing on 4 September.
The court heard that two police station readings were 60 micrograms of alcohol per 100 millilitres of breath - the legal limit is 35.
First of all Simon:
- Arsehole, you could have killed someone.
- You're one of the stars of one of the top-rated shows in the UK. Why mess with that?
The police reports did not indicate if Gregson claimed to "own Wilmslow," nor did it indicate if Gregson referred to any female constables as "sugar tits" and there is no indication of any references to his opinion of Jewish people.
