# MenkyoQuest — Question ch5_trap_12

Chapter: Ch. 5 Driving Method
Section: 第5節 進路変更など
Type: True/False
Difficulty: medium

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

## Correct 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.

## Driving school curriculum
Stage 1 – Topic 10: Lane changes and similar maneuvers

## Source passage (Rules of the Road)
Rules of the Road, Ch.5 §5 (Changing course) — Signal at least 3 seconds before changing lanes or course; never change where a no-lane-change marking (yellow solid line on lane boundary) is in effect. Confirm safety by checking mirrors and blind spots.
