It’s illegal to smoke in any motor vehicle when there are any passengers under ___ years old.
- 19
- 16 ✓
- 18
- 17
Answer: B. 16
It is illegal to smoke in a motor vehicle when any passenger is under 16 years old.
Why this is the answer
The handbook passage states the smoking rule directly: smoking in a motor vehicle is illegal when passengers are younger than 16. It also explains that children in cars are especially vulnerable to second-hand smoke, and that small enclosed spaces like vehicles can make those harmful effects immediate and serious. That supports using 16 as the age cutoff in the question.
Why the other answers are wrong
- A. 19 — The passage sets the smoking ban at under 16, not 19, so 19 is not the stated age threshold.
- C. 18 — The handbook says under 16, not 18, so 18 does not match the age given for this rule.
- D. 17 — The cutoff in the passage is under 16, not 17, so 17 is not the stated age.
Remember it
Think of 16 as the line: passengers below it mean no smoking in the vehicle.
