"As a player in this community, it's not good enough. This is a lesson everyone should take out of this: if you're not right to drive, have a Plan B.
"Once again, I am very sorry. I have full support from the club here at South Sydney."
Inglis, who revealed he spoke to Mal Meninga on Tuesday morning, refused to stand down from the captaincy despite a number of calls for him to be sacked.
The veteran rugby league centre was attending the Koori Knockout in Dubbo and revealed he was up past midnight drinking.
"I went out to the knockout, giving back to the community and seeing all the kids smile in Dubbo. I went back to the hotel and thought I'd be right to drive (the next day)," he said.
Inglis said he kept drinking until about 11pm to 1am on Sunday night and then left Dubbo for Sydney at midday on Monday.
"Went back to the hotel. Around 11pm, 1am. I don't think I left until about 12pm the next day. Got pulled over. That was it for me," he said.
Inglis said the situation from here on was "out of his control" and his position at the Kangaroos was "up to the selectors".
"I've been an NRL player for 13 years and I've never had a criminal charge laid against me," Inglis said.
He will plead guilty before court next month.
The NRL were on Tuesday morning going over the case and at this stage no announcement has been made on whether any action will be taken against him.
However, Australian selector Laurie Daley has already suggested Inglis relinquish the position, after he was charged with mid-range drink driving.
"It has to change things," he said on the Big Sports Breakfast. "Greg's been a terrific leader for South Sydney and Queensland but I don't think you can have the Australian captain going DUI."
"I'm pretty sure Greg and Mal (coach Mal Meninga) will come to the decision that he needs to step down as captain of his country."
Daley said the charge would likely spell the end of Inglis's tenure as Kangaroos captain before it had even begun.
"He's let himself down. He's let the game down ... and he'll pay a massive price for that," the chief national selector said.
Should Inglis lose the captaincy, vice-captain Boyd Cordner is tipped to be promoted to the job just days after leading the Sydney Roosters to NRL premiership glory.
Kangaroos forward Josh Papalii was last year stood down from a Test against New Zealand after pleading guilty to drink driving.
However, Papalii was originally named in the squad three-and-a-half months after the incident, and did not lose his position until after his plea in court. Crucially, Inglis's date in court won't arrive until after this month's Tests against New Zealand and Tonga in Auckland.
Jesse Bromwich lost the Kiwi captaincy when he and Kevin Proctor lost their places in New Zealand's World Cup squad after a night out in Canberra following a Test loss that resulted in no charges.
Queensland Origin coach Kevin Walters admitted it was disappointing Inglis found himself in the situation.
"I feel for Greg but also understand there is a responsibility that goes with being Australian captain and what needs to be upheld," he said "Mal has spoken quite openly about what his expectations are around the team environment, particularly from his senior players.
"I expect that they'll make a decision this morning on it." Inglis had his licence suspended and is scheduled to appear in Lithgow Local Court on November 22.
