Can traffic officers use visual and audible signals?
Signage: Traffic officers
Explanation
Traffic **officers** have the ability to make both **visual signals** and **audible signals** to direct and control traffic.
- **Visual signals**: Officers can use **arm signals** and **lights** to communicate instructions to drivers. For example, they can indicate to drivers to stop or slow down through specific arm movements or by directing a light towards them.
- **Audible signals**: Officers can also use **whistles** to emit sound signals. These sound signals are important to capture the attention of drivers and ensure that instructions are clear, especially in situations where ambient noise may hinder visual communication.
Therefore, traffic officers are equipped to use both types of signals, thus ensuring effective and safe communication in traffic management.
