Ch. 5 · Driving Method

The vehicle in front was slow to start, so I sounded the horn to urge it to move.

[True / False · Medium]

Answer: ✕ False

Explanation

The Rules of the Road state that the horn may only be sounded at locations with a "Sound Horn" sign, in sections with a "Horn Section" sign when passing through places with poor visibility, or when unavoidable to avoid danger, and must not be sounded otherwise. Using it to urge someone to start is a violation.

Seems fair, though—if they're slow, a little honk helps, right?

Not at all. You can only use the horn at designated spots, in poor-visibility sections, or to avoid danger. Urging someone to start is a violation, so the statement is false.

Wait, so I just… sit there and wait?

Yes. Patience is required. The horn isn't for impatience—it's for safety.
