The 35-year-old two-time World Cup winner who plays at Paris club Racing 92 was arrested in February on charges that can carry custodial sentences of two years.
Carter, who played 112 Tests for New Zealand, lost a sponsorship with Land Rover over the incident, which dented his image as one of rugby's most marketable players.
The athlete was pulled over and breathalysed in Paris' chic 17th arrondissement and returned a reading showing a level of 0.87mg/l, which would see a driver lose six points from their licence.
"It would not seem necessary, given the slight gravity of the facts, to pronounce a prison sentence," the document from October reads.
"Much as I'd love to say I've moved on from it, it's something I'm going to have to live with for the rest of my life," Carter said in October.
"It actually made me feel sick and it makes me feel sick now, thinking and talking about it.
Carter will leave Racing 92 and sign a two-year contract with Japanese club Kobelco Steelers at the end of the season.
