Quiz #1: Alcohol, Drugs, and Impaired Driving
Q1: According to the Florida BDI curriculum, alcohol is classified as which type of drug?
A. A depressant that slows the central nervous system [CORRECT]
B. A stimulant that increases alertness and reaction speed
C. A narcotic that relieves pain and induces sleep
D. A hallucinogen that distorts perception and senses
Correct Answer: A
Rationale: The Florida BDI curriculum classifies alcohol as a depressant because it slows brain function,
judgment, vision, and reaction time; stimulants (B), narcotics (C), and hallucinogens (D) describe entirely
different drug categories with opposite or unrelated effects.
Q2: Under Florida law, a driver age 21 or older is presumed to be driving under the influence when his
or her blood alcohol concentration (BAC) reaches:
A. 0.05 percent
B. 0.10 percent
C. 0.08 percent [CORRECT]
D. 0.02 percent
Correct Answer: C
Rationale: FLHSMV and Florida Statute 316.193 set the per se DUI limit at 0.08 percent for drivers 21 and
older; 0.10 percent (B) is an outdated misconception, and 0.02 percent (D) applies only to drivers under 21
under zero tolerance.

Q3: A 19-year-old college student is stopped at a checkpoint and tests at a BAC of 0.03. Under
Florida's zero-tolerance law, the most likely result is:
A. A written warning, because 0.03 is below the 0.08 adult limit
B. An automatic six-month driver license suspension [CORRECT]
C. No penalty, because the driver is over 18
D. An immediate criminal DUI conviction
Correct Answer: B
Rationale: Florida's zero-tolerance law (s. 322.2616) suspends the license of any driver under 21 for six
months at a BAC of 0.02 or higher; the 0.08 adult limit (A) does not protect a minor, and no measurable
alcohol is tolerated (C).
Q4: The liver oxidizes and eliminates alcohol at an average rate of about:
A. Two standard drinks per hour
B. Half a drink every ten minutes
C. A rate that depends entirely on body size
D. One standard drink per hour [CORRECT]
Correct Answer: D
Rationale: The BDI curriculum teaches that the liver processes approximately one standard drink per hour,
and nothing - not coffee, exercise, or cold showers - speeds this up; answers A and B greatly overstate the
elimination rate.
Q5: Florida's Implied Consent Law means that by accepting a driver license, you have agreed to:
A. Submit to a lawful breath, blood, or urine test when stopped for suspected DUI [CORRECT]
B. Allow police to search your vehicle at any time
C. Answer every question an officer asks about your activities
D. Submit to random chemical testing at any hour of the day
Correct Answer: A
Rationale: Under the Implied Consent Law, driving is a privilege conditioned on agreeing to chemical
testing upon a lawful DUI stop; it does not authorize vehicle searches (B), compelled interrogation (C), or
random testing (D).
Q6: Which of the following contains about the same amount of pure alcohol as one 12-ounce can of
regular beer?
A. Three ounces of 80-proof whiskey
B. A 16-ounce glass of table wine
C. A 5-ounce glass of table wine [CORRECT]
D. Two 12-ounce wine coolers
Correct Answer: C
Rationale: One standard drink equals 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of 80-proof liquor
- each contains about 0.6 ounce of pure alcohol (Florida BDI curriculum); option A is roughly two drinks,
and B and D far exceed one.

Q7: You have consumed four standard drinks over two hours. Assuming you eat a full meal and feel
alert, the minimum time before all the alcohol leaves your system is:
A. About one hour, since food slows alcohol absorption
B. About four hours, since the liver removes roughly one drink per hour [CORRECT]
C. About thirty minutes with strong black coffee
D. About two hours, matching your drinking window
Correct Answer: B
Rationale: Elimination is governed by liver metabolism at roughly one drink per hour regardless of food,
coffee, or how sober you feel; options A, C, and D all contradict the one-drink-per-hour rule taught in the
BDI course.
Q8: According to the statistics cited in the Florida BDI curriculum, approximately how many
Americans will be involved in an alcohol-related crash at some point in their lives?
A. Fewer than 1 in 100
B. About 1 in 20
C. About 1 in 4
D. About 3 in 10 [CORRECT]
Correct Answer: D
Rationale: The BDI curriculum cites the well-known estimate that three in ten Americans will be involved
in an alcohol-related crash in their lifetime, a rate far higher than the rare-exception figures in A, B, and C.
Q9: You are meeting friends at a restaurant and plan to drink. The safest and most legal plan is to:
A. Choose a designated sober driver before the first drink is poured [CORRECT]
B. Drink only beer, which is weaker than hard liquor
C. Eat a large dinner so the alcohol will not affect you
D. Wait thirty minutes after your last drink and then drive home
Correct Answer: A
Rationale: Designating a sober driver before drinking is the only plan that guarantees an unimpaired driver;
beer contains the same alcohol per standard drink as liquor (B), food slows but does not prevent impairment
(C), and thirty minutes cannot clear multiple drinks (D).
Q10: Many drivers who are well over the legal limit still insist they are 'fine to drive' because:
A. Their vision and coordination remain completely unaffected by alcohol
B. Alcohol impairs judgment and self-control first, so drinkers cannot accurately judge their own
impairment [CORRECT]
C. Breath testers routinely overstate a person's true BAC
D. Tolerance allows regular drinkers to drive as safely as sober drivers
Correct Answer: B
Rationale: The BDI curriculum stresses that alcohol's earliest effects fall on judgment and inhibition, which
destroys the ability to self-assess; vision and coordination are also impaired (A), chemical tests are
scientifically validated (C), and tolerance does not lower BAC (D).

Q11: Mixing alcohol with a second depressant, such as a sleep medication, will typically:
A. Cancel out the sedating effects of both substances
B. Simply double the time alcohol stays in the stomach
C. Multiply the impairing effects, creating a dangerous synergistic reaction [CORRECT]
D. Have no additional effect if the medication is prescription strength
Correct Answer: C
Rationale: The BDI curriculum teaches that combining depressants produces a synergistic effect in which
impairment is multiplied, not merely added; options A, B, and D are dangerous myths that lead to
combination-impaired driving.
Q12: A first refusal to submit to a lawful breath test in Florida results in:
A. A small fine with no license consequence
B. Suspension only if you are later convicted of DUI
C. A thirty-day warning suspension
D. An automatic 12-month driver license suspension [CORRECT]
Correct Answer: D
Rationale: Under Florida's Implied Consent Law, a first refusal triggers an automatic 12-month suspension
whether or not a DUI conviction ever follows, which rules out options A, B, and C.
Q13: At a party, your friend has had three drinks in one hour, insists he feels fine, and plans to drive
home after 'a couple of coffees.' You should:
A. Help arrange another ride or take the keys, because only time sobers him up [CORRECT]
B. Let him drive, since the coffee will restore his judgment within twenty minutes
C. Let him drive as long as he promises to stay under the speed limit
D. Encourage a cold shower and a big plate of food before he leaves
Correct Answer: A
Rationale: Coffee, showers, and food do nothing to lower BAC; the liver needs about one hour per drink,
so the responsible actions are arranging a safe ride or preventing him from driving (Florida BDI
curriculum).
Q14: You drank two glasses of wine with dinner between 8:00 and 9:00 p.m. At 10:00 p.m. you feel
completely normal. Legally and safely, you should:
A. Drive, because feeling normal means your BAC is below 0.08
B. Drive, because wine consumed with food is absorbed harmlessly
C. Wait longer or find another ride, because two drinks take about two hours to clear and you
cannot feel your true BAC [CORRECT]
D. Drive only on low-speed residential streets
Correct Answer: C
Rationale: Feelings are unreliable indicators of BAC; two standard drinks require roughly two hours for
elimination, so at 10 p.m. you may still be near or over the limit (Florida BDI curriculum,
one-drink-per-hour rule).
