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.
