Ask Your Teacher My Notes Question Part Points 1 –/10 Total –/10 When a person in California renews the registration for an automobile, the bar graph shown below is included with the bill. Use this bar graph to answer the question. The following statement is included with the graph. There is no safe way to drive after drinking. These charts show that a few drinks can make you an unsafe driver. They show that drinking affects your BLOOD ALCOHOL CONCENTRATION (BAC). The BAC zones for various numbers of drinks and time periods are printed in white, gray, and red. HOW TO USE THESE CHARTS: First, find the chart that includes your weight. For example, if you weigh 160 lbs., use the "150 to 169" chart. Then look under "Total Drinks" at the "2" on this "150 to 169" chart. Now look below the "2" drinks, in the row for 1 hour. You'll see your BAC is in the gray shaded zone. This means that if you drive after 2 drinks in 1 hour, you could be arrested. In the gray zone, your chances of having an accident are 5 times higher than if you had no drinks. But if you had 4 drinks in 1 hour, your BAC would be in the red shaded area . . . and your chances of having an accident 25 times higher. Suppose that you are over 18 years of age, weigh 195 pounds and have two drinks in 2 hours. According to the figure, are you seldom illegal, maybe illegal, or definitely illegal? seldom illegal maybe illegal definitely illegal 14. –/10 points.
