Ant McPartlin had five months cut from his road ban after completing a driving course.
The TV star, 43, was banned from the road for 20 months and fined £86,000 last year, after pleading guilty to driving while more than twice the legal limit.
He has now been allowed behind the wheel again and been spotted with girlfriend Anne-Marie Corbett, who was in the passenger seat.
The pair were pictured in The Sun, with Ant driving his Range Rover in London.
The presenter previously told police he was "ashamed and mortified" after crashing his car while drink-driving, with his mother in the passenger seat.
Wimbledon Magistrates' Court heard that he had been seeking help for "alcohol and emotional issues" at the time of the crash in Richmond, west London, on March 18 last year, having split from his partner of 11 years.
Sentencing the star, District Judge Barbara Barnes told him his behaviour had left fans disappointed and stripped him of his former "exemplary" character.
The presenter and his estranged wife Lisa were granted a divorce in under 30 seconds in October last year.
