A DRINK-driver almost four times the legal limit was among racegoers breath-tested leaving the 150th Launceston Cup yesterday.
Police conducted about 4000 random breath tests at sites around Mowbray Racecourse.
Officers charged two drivers with having exceeded the legal blood-alcohol limit of 0.05.
The highest reading was a BAC of 0.189 and the driver will face court at a later date.
Launceston Sergeant Nick Clark said police aimed for zero detections and were concerned with the high reading.
Inspector Michael Johnston said the behaviour of crowds within the racecourse was excellent, while no major incidents were reported in licensed venues last night.
