What should you exercise when you see a red and green light signal?

When encountering a red and green light signal, exercising caution is essential. This type of signal typically indicates that there may be a need for alertness and vigilance. The presence of red suggests a warning or the need to slow down, while green indicates that it is safe to proceed but still requires careful observation of your surroundings.

In aviation and air transportation, red and green light signals can convey important information about potential traffic or hazards in the vicinity. By exercising caution, one ensures that they are prepared to react appropriately to any changing conditions or unforeseen circumstances that might arise while navigating.

Confidence in proceeding is not warranted in this situation because the mixed signals imply that conditions are not entirely clear. Returning to the starting point may be excessive unless specifically advised, and stopping immediately could lead to confusion or create a hazard for those following behind. Therefore, the correct response is to exercise caution, allowing for the flexibility to adjust actions based on ongoing assessments of the situation.
