You are 19 years old. Under Pennsylvania's Zero Tolerance law, at what blood alcohol level are you considered to be driving under the influence?
-
A.
.05 or greater
-
B.
.08 or greater
-
C.
.02 or greater Correct
-
D.
.01 or greater
The answer is ".02 or greater"
Pennsylvania's Zero Tolerance law sets the DUI threshold for drivers under 21 at .02 blood alcohol concentration. The trap in this question is option B. The .08 figure is the threshold for drivers 21 and older, stated in the paragraph just above the under-21 rule, and test-takers carrying a single BAC number pick it here.
The traps in the wrong answers
A. .05 or greater
The .05 value appears only as an impairment comparison for 18 hours without sleep. Borrows a figure from the fatigue sidebar and treats it as the under-21 DUI limit.
B. .08 or greater
The .08 threshold is the DUI level for adults 21 and older. Applies the adult DUI figure to a driver under 21.
D. .01 or greater
The manual sets the under-21 DUI threshold at .02, not .01. Guesses a lower round figure without checking the printed Zero Tolerance number.
