Type: True/False

## Question
If the signal to the side is red, the signal ahead must be green.

## Correct answer
False

## Explanation
Article 1(2) of the Rules of the Road states that "even if the signal to the side is red, the signal ahead is not necessarily green." Special traffic lights exist, such as those where all directions are temporarily red or staggered-timing signals, so you must always check the signal ahead.
