Ch. 9 · Passenger & Substitute

Bus drivers must sound the horn when departing, except when safety has been confirmed immediately before departure.

[True / False · Medium]

Answer: ✓ True

Explanation

Chapter 9, Section 1(2)(i) of the Rules of the Road states: "Bus drivers must sound the horn when departing, except when safety has been confirmed immediately before departure." If safety has been confirmed just prior to departure, sounding the horn is not required.

Hikari

So bus drivers always have to honk when they leave, right?

Misaki

Actually, that's true—but there's an exception. If the driver already confirmed safety right before departing, the horn isn't required.

Hikari

Oh, so it's more about whether they've checked already?

Misaki

Exactly. The horn is a safety signal, but if you've just verified everything is clear, it's not mandatory.
