BAC and Impairment: How Much Can I Drink?

Blood alcohol content (BAC) measures the percentage of alcohol in a person’s blood, and this measurement is most commonly obtained through breath tests and blood tests.

Your BAC and how quickly you will become intoxicated is based upon a number of factors, including:
  • The amount of alcohol you have consumed
  • The type of alcohol you have consumed
  • The length of time you have been drinking
  • If you ate while drinking, and how much you ate
  • Your gender
  • Your weight
  • Your age
  • Your tolerance for alcohol
  • If you are taking certain medications
Alcohol affects everyone differently, but there are certain impairments that commonly occur when a person’s BAC reaches specific percentages. People typically exhibit the following signs of impairment the more alcohol they consume:
  • 0.01% to 0.02% BAC – You will appear normal, but you will exhibit subtle effects from the alcohol, which can be detected with specialized tests.
  • 0.03% to 0.05% BAC – Your ability to concentrate will be affected.
  • 0.06% to 0.09% BAC – Your ability to reason will be impaired and you will also notice effects on your depth perception, peripheral vision, and glare recovery.
  • 0.10% to 0.19% BAC – Your speech will be slurred and you may stagger, and your reaction time, reflexes, and gross motor control will be impaired.
  • 0.20% to 0.29% BAC – You will exhibit severe motor impairment, and may sustain memory blackout or lose consciousness.
  • 0.30% BAC or Higher – When an individual’s BAC is 0.3% or higher, they are at risk of alcohol poisoning and severe physical harm.
