Ant McPartlin has been given an £86,000 fine after being found guilty of drink driving at Wimbledon Magistrates' Court.
The TV presenter was also handed a 20-month driving ban after being found to be twice the legal drink drive limit.
Speaking after the hearing, Mr McPartlin said "I let myself down, I let a lot of people down. For that I'm truly sorry."
He also said he was glad no one was hurt in the crash, which took place on 18 March.
Mr McPartlin's mother was in the passenger seat of his Mini when the incident took place.
The driver of one of the cars said he and his wife "could have died as a result of Mr McPartlin's reckless driving".
A number of pre-recorded Britain's Got Talent shows mean Mr McPartlin will be on UK TV for the next couple of months, but his public apology is expected to be his last live TV appearance for some time.
The £86,000 penalty is thought to be one of the heftiest drink-drive fines handed out by a UK court.
District Judge Barbara Barnes took McPartlin's weekly income of £130,000 into account when arriving at the figure.
There were 75 microgrammes of alcohol per 100ml McPartlin's blood, the court was old. The legal maximum is 35 microgrammes/100ml.
When handing down the sentence the judge talked of McPartlin's previous "exemplary character", but went on: "I think it will have quite an impact on you to know you're no longer a man of good character."
The 20 month ban could be reduced to 15 if McPartlin agrees to attend a drink-drive referral programme.
