Understanding BAC Levels

Blood Alcohol Concentration is measured as a percentage of alcohol in the blood. Different BAC levels can lead to various effects:

• 0.02-0.03%: Slight euphoria and loss of shyness
• 0.04-0.06%: Feeling of relaxation, minor impairment of reasoning and memory
• 0.07-0.09%: Slight impairment of balance and speech, reduced reaction time
• 0.10-0.12%: Significant impairment of motor coordination and loss of good judgment
• 0.13-0.15%: Gross motor impairment and lack of physical control

Stay informed, drink responsibly, and always have a designated driver or use alternative transportation if you've been drinking.
