3. Blood Alcohol Concentration Determination
Blood Alcohol Concentration (BAC): amount of alcohol in the blood at any given time.
Only thing that lowers BAC is time.
Factors that affect: gender, amount ingested, weight, speed of consumption, metabolism, food (amount and type), medications
Illegal to drive with BAC above 0.08.

Table 2: Average BAC based on Weight and Number of Drinks

4. Scenarios Use the chart. Subtract 0.015% for each hour of drinking.
Marisa: 120 pounds, 5 drinks between 9 pm and 12 am.
BAC = (chart results) – (hours drinking x 0.015)
BAC =
Scenario 2

5. Scenarios Use the chart. Subtract 0.015% for each hour of drinking.
Marisa: 120 pounds, 5 drinks between 9 pm and 12 am.
BAC = (chart results) – (hours drinking x 0.015)
BAC = 0.20
Scenario 2

6. Scenarios Use the chart. Subtract 0.015% for each hour of drinking.
Marisa: 120 pounds, 5 drinks between 9 pm and 12 am.
BAC = (chart results) – (hours drinking x 0.015)
BAC = – (3 x 0.015)
Scenario 2

7. Scenarios Use the chart. Subtract 0.015% for each hour of drinking.
Marisa: 120 pounds, 5 drinks between 9 pm and 12 am.
BAC = (chart results) – (hours drinking x 0.015)
BAC = – (3 x 0.015)
BAC = 0.20 – (0.045)
Scenario 2

8. Scenarios Use the chart. Subtract 0.015% for each hour of drinking.
Marisa: 120 pounds, 5 drinks between 9 pm and 12 am.
BAC = (chart results) – (hours drinking x 0.015)
BAC = – (3 x 0.015)
BAC = 0.20 – (0.045)
BAC = 0.155
Scenario 2
