## Question
Which statement about preventing drunk driving is correct?

## Options
A. You may serve alcohol to someone who is about to drive a vehicle, but you must not offer it to them
B. You must not serve or offer alcohol to someone who is about to drive a vehicle
C. You may offer alcohol to someone who does not have a driver's license
D. If a drinking person hires a substitute-driving service (運転代行), they must NEVER ride in their own vehicle while the substitute driver operates it

## Correct answer
B. You must not serve or offer alcohol to someone who is about to drive a vehicle

## Explanation
The Rules of the Road, Chapter 1, Section 4, Item 5 explicitly states "you must not serve or offer alcohol to someone who is about to drive a vehicle." Both serving and offering alcohol are prohibited. On option D: the Rules do NOT forbid a drinking person from riding as a passenger while a substitute-driving service (運転代行) drives their car — that is in fact the normal use of the service.
