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

According to the manual, which body samples can a chemical test use to measure a driver's BAC?

  1. A.
    Only blood drawn at a hospital.
  2. B.
    Hair, fingernails, or skin swabs.
  3. C.
    Blood, breath, urine, or saliva. Correct
  4. D.
    Only breath from a breath analyzer.
The Why

The answer is "Blood, breath, urine, or saliva."

The manual lists blood, breath, urine, and saliva as the four samples a chemical test can use. A takes the most precise sample as the only sample the law allows, treating a hospital blood draw as if it were the sole authorized option.

Why the others miss

The traps in the wrong answers

A. Only blood drawn at a hospital.

Blood is one of the four samples the manual lists, but it is not the exclusive one. This answer confuses the most precise sample with the only sample the law allows.

B. Hair, fingernails, or skin swabs.

None of these appear in the manual's list of chemical-test samples. This answer borrows forensic-identification samples from crime-lab shows and applies them to a BAC test.

D. Only breath from a breath analyzer.

Breath is one of four permitted samples, not the only one. This answer treats the roadside device most drivers have heard about as the entire chemical-test toolkit.
