5 Eye-Opening Facts About BAC
Your BAC level can change rapidly. Here are key facts:
1.Individual Differences
Age, metabolism, medications, and more can impact your true BAC.
2.Time Matters
Your body typically processes 1 standard drink per hour, but many factors vary this rate.
3.Tolerance vs. BAC
Even if you feel fine, your BAC might still be high—tolerance can mask impairments.
4.Legal Limits
Many regions set 0.08% as the legal driving limit, but impairment can start lower.
5.Staying Safe
Plan a ride or designate a driver to avoid the dangers of driving under the influence.
