Your chances of being in a collision begin to increase after consuming:
- Four alcoholic drinks.
- Three alcoholic drinks.
- Two alcoholic drinks.
- One alcoholic drink. ✓
Answer: D. One alcoholic drink.
Your chances of being in a collision start to go up after just one alcoholic drink.
Why this is the answer
The handbook says alcohol begins affecting you almost right away, and judgment is the first skill it touches. Even a single drink can change how you judge distance, speed, and the movement of other vehicles, and it slows your reflexes. The handbook states plainly that after even one drink your chances of a crash are much greater than if you had none, so the increase starts at one drink, not at two or more.
Why the other answers are wrong
- A. Four alcoholic drinks. — Waiting until four drinks is far too late, since the handbook says the risk is already higher after the very first drink.
- B. Three alcoholic drinks. — Three drinks is also past the point the handbook identifies, because the added crash risk begins with even one drink.
- C. Two alcoholic drinks. — Two drinks is still more than the handbook's threshold, which puts the start of increased risk at a single drink.
Remember it
Picture the count starting at one, not three or four: the handbook's rule is that one drink is one too many.
