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

## Question
Supplementary signs supplement the meaning of main signs, so all regulatory signs always have a supplementary sign attached.

## Correct answer
False

## Explanation
The Rules of the Road states that supplementary signs are sometimes used to supplement the meaning of main signs such as regulatory signs. As an exception, there are many main signs that do not require supplementary signs or do not use them. The expression "usually attached below the main sign" also indicates that they are not always attached.
