Driver's License Test Prep
New York Practice DUI & Impaired Driving

When do alcohol's effects on your driving abilities begin?

  1. A.
    After the third drink for most adults.
  2. B.
    After you pass the legal BAC limit.
  3. C.
    With the first drink you consume. Correct
  4. D.
    Only when you feel or look intoxicated.
The Why

The answer is "With the first drink you consume."

The manual is direct: alcohol begins weakening driving abilities with the first drink, long before you would be intoxicated or legally impaired. The trap is B: drivers treat the printed BAC limit as the line where impairment starts because that is the only alcohol number attached to the word 'limit' in the manual, but the onset comes far earlier than any legal cutoff.

Why the others miss

The traps in the wrong answers

A. After the third drink for most adults.

The manual gives no drink-count threshold; onset begins with the first drink. This answer borrows a rule of thumb from bar conversation and reads it into the manual.

B. After you pass the legal BAC limit.

This answer sets the wrong threshold; the manual says effects begin far before the legal limit. It treats the printed BAC limit as the line where impairment starts, because that is the only alcohol number a new driver has memorized.

D. Only when you feel or look intoxicated.

The manual states that you do not have to look or feel intoxicated for these things to occur. This answer trusts visible tells because impairment feels easier to accept when it can be seen.
