There’s a long and complicated explanation contained with the new online set of rules of racing.
But essentially, the breath testing is random in terms of when it is done and all jockeys at a chosen meeting can be tested.
The lower limit is 17 mls, which I think is half the driving limit, and any reading over that requires that the jockey then provide a urine sample. They are automatically banned for that day if over the breath test limit and can subsequently be banned for more days.
Fist,
It was a second offence for Carberry, hence the length of his ban. I’ve no idea how the Irish system works, or what the limits are over there, although it seems reasonable to assume they’d be the same.
