Chapter: Ch. 9 Passenger & Substitute
Section: 本文
Type: True/False
Difficulty: medium

## Question
A bus driver must sound the horn before departure unless a safety check was completed immediately before, but when a conductor is on duty, the driver must absolutely never depart without the conductor's signal.

## Correct answer
True

## Explanation
When departing, a bus driver confirms safety and gives a signal (including use of the horn) before pulling out, and when a conductor is aboard, departs only on the conductor's signal. Both parts of this statement — giving a signal unless safety has been confirmed, and not departing without the conductor's signal when a conductor is aboard — are correct, so the statement as a whole is correct.
