Keeping a BAC of less than 0.06 will let you enjoy your social time without the risks of heavy alcohol consumption.
Don't be "BLUE" and don't get caught in the "RED"!
Like the Green Zone, there is a Blue and Red Zone. Negative consequences (e.g. fights, DUI, unprotected sex) are associated with high a BAC: The BLUE and RED zone! So use the BAC card to help you "Stay in your GREEN Zone!"
Stay Green and Don't Zone:
DANGER: BLUE ZONE!
0.06 - 0.09 = Judgment, perception and information processing are impaired; poor decision making; speech begins to slur; vision and hearing are diminished; balance and motor-skills are reduced.
0.10 - 0.24 = Impairments in coordination, balance and memory; difficulty in walking, talking and standing. Negative emotions increase.
RISK OF SERIOUS HARM: RED ZONE!
0.25 - above = Severe impairment in mental, physical and sensory functions. Mental confusion and loss of consciousness is likely. Risk of serious injury and death is increased.
