The Stoke winger's guilty plea saw him avoid serving time in prison but he has been banned from the road for three years after a string of motoring offences
When Pennant was arrested back in April, his blood alcohol level was over twice the legal limit.
The former England under-21 man was also driving without a licence while serving an existing driving ban.
Pennant claimed that he was suffering from depression and stress, and the drink-driving was a result of taunts he received at a Manchester nightclub.
His lawyer claimed that the incident was brought on by domestic problems surrounding a break-up with his girlfriend earlier that afternoon.
The former Birmingham man was jailed for 30 days in 2005 and became the first player in the Premier League to appear on the pitch while fitted with an electronic tracking tag.
He attained further notoriety after initially claiming to be former Arsenal team-mate Ashley Cole when pulled over by police.
