# MenkyoQuest — Question ch3_trap_03

Chapter: Ch. 3 Bikes & E-Mobility
Section: 第3節 安全な通行
Type: True/False
Difficulty: medium

## Question
A 70-year-old elderly person riding a standard bicycle was traveling on a sidewalk with no sign when a police officer warned them. However, since elderly people aged 70 and over may use sidewalks, this police officer's warning was unjustified.

## Correct answer
False

## Explanation
Trap point: the first half — "riders aged 70+ may use the roadway-side portion of a sidewalk even without a sign" — is correct. But jumping from that to "the officer's warning was unjustified" is wrong. When a police or traffic-directing officer restricts sidewalk use to protect pedestrians, the on-scene instruction takes priority (Road Traffic Act §63-4). A general permission can be overridden by a specific safety instruction.
