The driver's license is automatically suspended and refusal may be used as evidence

Question 2

Which of the following is a standard field sobriety test (FST) recognized by the National Highway Traffic Safety Administration (NHTSA)?

Accepted Answer

The one-leg stand test

Answer

NHTSA has standardized three FSTs: the Horizontal Gaze Nystagmus, the Walk-and-Turn, and the One-Leg Stand test.

Question 3

How long does it generally take the liver to metabolize one standard drink (0.6 oz of pure alcohol)?

Sedating antihistamines can cause drowsiness, slowed reaction time, and impaired coordination, making them particularly dangerous when driving.

Accepted Answer

A DUI involving a BAC significantly above the legal limit, a minor passenger, or prior convictions
