You are 18 years old. A preliminary alcohol screening (PAS) shows your BAC is 0.05%. What can the officer require next?
-
A.
Nothing further, since 0.05% is below the adult limit.
-
B.
A breath or blood test. Correct
-
C.
Only a written statement of what you drank.
The answer is "A breath or blood test."
For drivers under 21, a preliminary alcohol screening reading of 0.05% or higher lets the officer require a breath or blood test. Choice A applies the adult 0.08% threshold that under-21 drivers hear quoted most often, missing that the under-21 escalation trigger sits lower at 0.05%.
The traps in the wrong answers
A. Nothing further, since 0.05% is below the adult limit.
Under 21, the officer can escalate at 0.05%; the adult 0.08% figure does not apply. This answer reads the 0.08% adult threshold as universal, borrowing the number under-21 drivers hear quoted most often for DUI.
C. Only a written statement of what you drank.
The manual authorizes a chemical test at 0.05%, not a self-reported statement. This answer substitutes a self-report for the chemical test, treating the traffic stop like an underage-possession interview at the roadside.
