Show answer
Answer: A. The photo and physical description, such as height and eye color
Make sure the face and description match the person. A real ID that belongs to someone else is a common way minors try to buy alcohol.

- 3
- 2
- 4

- About 1
- About 3
- About 2
- About 0.5

Question 7 of 25
A guest stops drinking at 11 p.m. What can happen to their BAC after that?
- It can keep rising for a while
- It drops to zero within 15 minutes
- It stays the same until they sleep
- It falls quickly if they drink coffee
Show answer
Answer: A. It can keep rising for a while
Alcohol still in the stomach and intestine keeps being absorbed, so BAC can continue to rise after the last drink.
Question 8 of 25
You are unsure whether an ID belongs to the customer. What is a good way to check?
- Ask them to tell you details from the card, such as their middle name or ZIP code
- Check their phone wallpaper
- Ask them their favorite color
- Ask a friend to vouch for them
Show answer
Answer: A. Ask them to tell you details from the card, such as their middle name or ZIP code
The real owner can easily say the details printed on the card. Hesitation or wrong answers are warning signs.

- Let them sleep it off in a back room
- Give them coffee
- Call 911 and stay with them
- Put them in a cold shower

These are signs of alcohol overdose, which can kill. Call 911, do not leave them alone, and keep them on their side if they vomit.

- People hurt by an intoxicated person to sue the business that illegally served that person
- Bars to stay open all night

Show answer

Dram shop laws can make a business liable when it serves a minor or an obviously intoxicated person who then causes injury or death.
Question 11 of 25
Which of these can be a sign of a fake or altered ID?
- Raised edges, bumps, or numbers that look scratched or changed
- A clear, sharp photo
- A smooth, even surface
- Security features that change with the light
Show answer

Feel the card and look closely. Cuts, peeling lamination, blurry print or changed numbers can mean tampering.

- 0.04%
- 0.02%
- 0.08%
- 0.10%

Question 13 of 25

- It records what happened and shows you acted responsibly
- It is used to split tips
- It is required to sell more drinks

Question 14 of 25
How did the National Minimum Drinking Age Act of 1984 lead all states to adopt age 21?
- It created a national ID card
- It made 21 a federal criminal law
- It reduced federal highway funds for states with a lower age
- It banned alcohol sales to everyone under 25
Show answer
Answer: C. It reduced federal highway funds for states with a lower age
The law did not set the age directly. States that kept a purchase age under 21 lost part of their federal highway money, so every state adopted 21.
Question 15 of 25
Can an electronic ID scanner replace looking at the ID and the customer?
- Yes, if the scanner beeps
- No. You must still check that the photo matches the person and look for tampering
- Yes, the scanner does all the work
- Only on busy nights
Show answer
Answer: B. No. You must still check that the photo matches the person and look for tampering
A scanner can help, but it cannot tell whether the person in front of you is the person on the card.
Question 16 of 25
Why do women usually reach a higher BAC than men after drinking the same amount?
- Women usually have less water in their bodies to dilute alcohol
- Women cannot break down alcohol at all
- Women always drink faster
- Women absorb alcohol through their skin
Show answer
Answer: A. Women usually have less water in their bodies to dilute alcohol
On average, women have less body water than men of the same weight, so alcohol is more concentrated in the blood.
Question 17 of 25
A customer walks in already visibly intoxicated. What should you do?
- Serve them after they eat a snack
- Serve them one drink
- Do not serve them alcohol
- Serve them light beer only
Show answer
Answer: C. Do not serve them alcohol
Most states prohibit serving a visibly or obviously intoxicated person, no matter where they did their drinking.
Question 18 of 25
Every state has a "zero tolerance" law for drivers under 21. What does it mean?
- Drivers under 21 may drink one beer before driving
- Drivers under 21 can be penalized for even a small amount of alcohol in their system
- Only drivers over 21 can be arrested for drunk driving
- It applies only to motorcycles
Show answer
Answer: B. Drivers under 21 can be penalized for even a small amount of alcohol in their system
Because it is illegal for people under 21 to drink, states punish young drivers with very low BAC levels, far below 0.08%.
Question 19 of 25
Which kinds of consequences can a server face for illegal alcohol service?
- Criminal charges, civil lawsuits and penalties against the license
- None, only the owner is ever responsible

Question 21 of 25

- The strength of a drink
- The amount of alcohol in a person's blood
- How fast a person can walk
- How many drinks a person has bought
Show answer

BAC is the percentage of alcohol in the blood. A BAC of 0.08% means 0.08 grams of alcohol per 100 milliliters of blood.

A regular customer with a high tolerance shows few signs after several drinks. What is true?
- They cannot become intoxicated
- Tolerance makes the liver work twice as fast
- Their BAC can be high even though they seem sober
- Their BAC is lower than other people's
Show answer
Answer: C. Their BAC can be high even though they seem sober
Tolerance can hide the signs of intoxication but does not lower BAC. The customer is still impaired.

A cocktail contains three 1.5-ounce pours of different 80-proof liquors. How many standard drinks does it contain?
- 2
- 1
