Hooo, LZ, no worry, you've only been tested on the prelim device, and the result showed below the limit of BAC, if it showed a value of over limit, you will be summoned to the bus for a further test using a dragger machine.
BUT, be carful when driving, if you drink dont drive, if you drive dont drink!
AND dont fool yourself: speed kills! Get buckled whenever the car engine is running!
