Question: 1 / 445

What is the required action in the yellow zone on the speed dial?

Apply emergency braking

Increase speed

Apply service braking

In the context of operational protocols related to speed dial systems, the yellow zone typically serves as a cautionary area indicating that immediate attention is required but does not constitute an emergency. The correct action in this zone is to apply service braking. This means that the operator should reduce speed gradually, which helps ensure safety without the abruptness of emergency braking. By applying service braking, a trained individual can manage the situation effectively, allowing for a controlled response to potential hazards indicated by the yellow zone.

Service braking establishes a balance between maintaining control and ensuring the vehicle's speed is appropriate for the conditions, thereby minimizing risks. This is essential for maintaining operational safety and is a standard procedure when encountering indications that necessitate caution but do not warrant a full emergency response.
