- They are vertical (portrait) instead of horizontal
- They have no photo
- They are made of paper
Show answer

Many states print vertical cards for drivers under 21 so servers can spot them quickly. Always check the date of birth too.
Question 18 of 25
Two customers drink the same amount in the same time. Who will usually have the higher BAC?
- The person drinking light beer
- They will always be the same

A smaller person has less body water to dilute alcohol, so the same amount produces a higher BAC.
