# MenkyoQuest — Question ch1_sign_37

Chapter: Ch. 1 Common Conduct
Section: 第２節 信号
Type: True/False
Difficulty: medium

## Question
A lane with a bus-only lane marking cannot be used by any vehicles, so general vehicles must not enter even in emergencies.

## Correct answer
False

## Explanation
A bus-only lane is a regulatory marking defined by Road Traffic Act §20 and the Rules of the Road Ch.1 §2. In principle non-bus vehicles cannot use it, but exceptions exist for right/left turns, where signs or markings expressly permit it, or for emergency vehicles (§20(2)). "No vehicles can use it" and "entry prohibited in any case" are incorrect — operating hours and exception conditions must be checked.
