The British sprinter smashed his luxury Audi head-on into the cab, which was carrying a newlywed couple, near his ex-girlfriend's home in Buckinghamshire, England in May last year (10).
Christie admitted the accident happened after he suffered a "lapse", telling a court in England this week (beg18Jul11), "I was just driving along and the next thing I knew, I saw a light and we had a crash, and that was it... I accept that it was my fault."
On Thursday (21Jul11), the athlete, who took gold in the 100 metres at the Barcelona Olympics in 1992, was found guilty of careless driving but was cleared of a more serious charge of dangerous driving.
He was banned from getting behind the wheel for 15 months and ordered to pay an $8,000 (£5,000) fine and $1,600 (£1,000) in court costs.
The retired sprinter, 50, is facing the count following a car crash with a taxi in Buckinghamshire, England in May last year (10), which left both drivers and two passengers in the cab needing hospital treatment.
A police investigation into the collision found Christie to be at fault and he is now facing punishment over the crime.
Christie, who scooped gold in the 100 metres at the Barcelona Olympics in 1992, has denied the charge.
He appeared at a hearing in Aylesbury Crown Court on Wednesday (26Jan11) and will return to enter his plea on 9 March (11).
The veteran star has been camping with former Bond girl Britt Ekland, rocker Shaun Ryder and Olympic gold medallist Linford Christie as part of the series, which sees stars put to the test in trying tasks.
Havers threatened to quit in an episode screened on Sunday (21Nov10) after he was ordered to compete in a challenge in which the contestants received electric shocks.
After producers convinced him to continue on the programme, Havers gamely agreed to soldier on - but he eventually walked out of camp on Monday (22Nov10) and is now set to return to Britain.
In a statement posted on the show's official website, a spokesman says, "We can confirm that Nigel Havers has hung up his boots and left the jungle."
The former Bond girl flew to Australia over the weekend (06-07Nov10) in preparation for the show, which starts in the U.K. on Sunday (14Nov10).
Ekland admits she signed on to appear on I'm A Celebrity... to raise the profile of her autobiographical one-woman show, which toured Britain earlier this year (10) - and even though she's never watched the programme, she's adamant she'll be able to cope with all of the challenges of living in the wilderness.
She says, "Why did I sign up for the jungle? I have a one-woman show and I wanted an opportunity to raise my profile. I want people to come and see my show.
"I'm not scared of snakes, spiders or heights. I have three children as as a mum, you can't be afraid of things like that. I wouldn't say I'm a jungle Jane but I'm not afraid of anything. I'm usually working at this time of year, so I have never seen the show."
Other stars rumoured to be on the series include English actor Nigel Havers and Olympic-winning athlete Linford Christie.
The British athlete was travelling in his luxury Audi when it collided with a taxi in Buckinghamshire, England, according to The Sun newspaper.
Christie, who scooped gold in the 100 metres at the Barcelona Olympics in 1992, staggered from the vehicle and collapsed on the ground, clutching his stomach.
He was taken to hospital and released after treatment following the crash earlier this month (May10). Three men travelling in the taxi - including the driver - are still in hospital receiving treatment for their injuries.
