How many alcoholic drinks does it take to affect your driving ability?
- Three
- Two
- One ✓
Answer: C. One
It takes just one alcoholic drink to affect your driving ability.
Why this is the answer
The California handbook says that even one drink can affect your ability to drive safely. It explains that alcohol enters your bloodstream and that being below a legal BAC limit does not make driving safe, because almost everyone feels negative effects at lower levels. So the question is not about reaching some larger number of drinks; the handbook's direct warning is that a single drink is already enough to impair driving.
Why the other answers are wrong
- A. Three — Nothing in the handbook says three drinks are needed before alcohol affects driving; it warns that even one drink can do so.
- B. Two — The handbook does not set two drinks as the point where driving ability is affected; it says one drink can already affect it.
Remember it
Think of the first drink as the warning sign, not a safe starting point.
