The former leg-spinner admitted breaking a 40-miles-per-hour (64 KM/h) limit in a hired Jaguar in London last year, a magistrates´ court heard.
The 50-year-old, who was not in court for the hearing, was at 47 mph early on August 23, 2018.Warne, second on the all-time list of Test wicket-takers with 708 test wickets, had 15 penalty points on his licence at the time for five previous speeding challans.
Shane Warne, who lives in west London, was also ordered to pay a total of $3,000 to the court.
“The purpose of disqualification is to punish and protect the public and to deter,” said deputy district judge Adrian Turner.
“There are 15 points to take into account together with the 3 I must impose today. Between April 2016 and August 2018 Shane Warne committed six speeding offences.
“It may well be that none on its own were particularly serious but for points disqualification purposes the insignificance the offences is not to be taken into account.
“A period of at least 12 months is necessary for the purposes I have mentioned.”
