Another 449 drivers were banned for drink-driving three times in those four years with dozens caught more than that.
Two drivers were even prosecuted for the offence six times.
Motorists caught drink-driving face a ban of at least a year, an unlimited fine and in the most serious cases up to six months’ imprisonment.
But some are offered places on rehabilitation courses to reduce the length of their disqualification.
Edmund King, president of the AA, said: “The fact that more than 8,000 drivers have been caught twice in five years is all the more astonishing when they should have been off the road for a year or more.
“The repeat offender figures also suggest that a minority of drivers have a drink problem rather than a driving problem.
“Perhaps it is time to review some of the medical checks and rehabilitation courses before allowing these drivers back on the road.”
