3. You refuse the chemical test after a Wyoming arrest for driving under the influence. What may law enforcement do?

4. Which three things does the Wyoming manual say determine a person's blood alcohol concentration?

5. At what blood alcohol reading can a Wyoming driver be convicted of DWUI when there is other supporting evidence?
Correct answer: 0.05 percent

6. What does the Wyoming manual say about allergy pills and cold remedies?
Correct answer: They can bring on drowsiness and cloud clear thinking
Their ingredients can leave a driver drowsy and make clear thinking difficult, which is why the manual warns against assuming an over-the-counter drug is harmless.

7. A Wyoming driver under 21 is in physical control of a vehicle. At what alcohol level is a suspension imposed?

8. About how much farther does a drinking driver at 55 miles per hour travel before the brakes go on, according to the Wyoming manual?
Correct answer: About 32 feet

9. What danger does the Wyoming manual attach to diet and stay-awake pills?
Correct answer: They give a false feeling of alertness and encourage risk-taking

10. Two people drink the same amount of alcohol. What does the Wyoming manual say about the heavier one?
Correct answer: The heavier person will probably have a lower reading
More blood and body fluid dilutes the same quantity of alcohol further, so the heavier person will usually end up at a lower reading.

11. What does the Wyoming manual say actually lowers a person's blood alcohol concentration?
Correct answer: Nothing but letting time pass
Only the passing of time will bring the level down. A cold shower, black coffee or a workout accomplishes nothing.

12. How does alcohol interfere with a Wyoming driver's ability to identify hazards?
Correct answer: It fixes the gaze on one object and nearly wipes out awareness to the sides
Vision, hearing and the sense of body position all decline, drivers lock their gaze on one object, and the ability to notice traffic off to the sides is nearly gone.
