# MenkyoQuest — Question ch5_trap_05

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

## Question
When changing lanes, you must always confirm that there is a safe distance even if the vehicle behind you has to apply sudden brakes before changing.

## Correct answer
False

## Explanation
The Rules of the Road state that you must not change lanes if a vehicle coming from behind would have to use sudden braking or sudden steering to avoid you. As an exception, there are cases where you must change lanes unavoidably, so the absolute expression "must always" is incorrect.

## 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.
