A 3-minute lesson from the New Hampshire course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Alcohol and other impairing drugs are involved in approximately 40% of all traffic crashes in which someone is killed each year. Impairment starts with the first drink, and only time sobers you up.
About 40%
Share of fatal crashes each year involving alcohol or other impairing drugs
Drivers under 21 may not have physical control of a vehicle while under the influence of liquor, drugs or other impairing substances, or with an alcohol concentration of 0.02 or more.
Nothing but TIME reduces the effects of alcohol. Coffee, food, fresh air, exercise or cold showers may make you more alert, but won't counter the alcohol.
After three beers you drink two coffees and feel alert. You're still impaired: coffee doesn't counter alcohol, and each ounce takes about an hour to leave your body. Wait it out or get a ride.
