Repeating signal shows ________ light in ON condition.

Solution (By Examveda Team)

Let's break down what a repeating signal does and how it relates to the lights.
A repeating signal's main job is to repeat the indication of the signal ahead.
Think of it as a preview! It tells the driver what the next signal is showing.
The correct answer is Yellow.
Here's why:
When the signal ahead displays a restrictive aspect (caution), typically indicated by a Yellow light, the repeating signal will also show Yellow.
The purpose of yellow is to alert that the driver needs to reduce speed and be prepared to stop at the next signal.

Why not the other options?
Red: Red generally means Stop. Repeating signals wouldn't show Red in an 'ON' condition; they would show Yellow to indicate the following signal might be at Red (or another restrictive aspect).
Green: Green indicates Clear track ahead. If the signal ahead is Green, the repeating signal wouldn't need to be 'ON' to repeat a restrictive aspect.
