Topic overview

This chapter covers how alcohol and other drugs impair driving — slower reaction time, poor judgment of speed and distance, and reduced night vision — and why New York treats impaired driving as a leading cause of traffic deaths. It also explains New York's tiered offenses, from Driving While Ability Impaired (DWAI) up through Aggravated DWI, and the BAC (blood alcohol content) thresholds that define each one: 0.05% as legal evidence of impairment, 0.08% as intoxication, and 0.18% as aggravated.

The most-tested material is what BAC actually depends on — the amount you drink, the time between drinks, and body weight — and, just as important, what it does NOT depend on: the type of beverage, fitness level, or tolerance. New York's "Implied Consent" law and the consequences of refusing a chemical test are also frequently tested, along with the zero-tolerance rule for drivers under 21.

A common mistake is believing that coffee, exercise, or a cold shower can sober you up faster — the manual is explicit that only time reduces BAC. Test-takers also sometimes assume beer is "safer" than liquor per drink, when the manual notes that a standard serving of each contains roughly the same amount of alcohol.

What three factors determine your BAC?

How much alcohol you drink, how much time passes between drinks, and your body weight. Beverage type, physical fitness, and alcohol tolerance do not change your BAC — the manual is clear that no one is "immune" to alcohol's effects.

What is New York's "Implied Consent" law?

By driving in New York, you're considered to have already agreed to a chemical test (blood, breath, urine, or saliva) if arrested for an alcohol or drug violation. Refusing has its own consequences — including license suspension — separate from and in addition to the underlying charge.

What's the only way to lower your BAC?

Time. The manual states that food can slow how fast alcohol is absorbed, but nothing — not coffee, not exercise, not a cold shower — speeds up how fast your body actually removes alcohol from your blood.
