Which of the following characteristics do Traffic Officers' signals have?
Signage: Traffic officers
Explanation
**Traffic officers' signals** are always **executive**, which means they must be obeyed at all times, without exception. This is because officers have the authority to direct traffic and ensure road safety.
- Officers can give signals in different ways, such as with their **arm**, **whistles**, or from a **vehicle**. All these signals are equally valid and must be followed by drivers.
- Arm signals, for example, can indicate to drivers to stop or slow down. These signals are clear and visible, and drivers must obey them until the officer indicates otherwise.
- From a vehicle, officers can use **flags** of different colors or flashing lights to communicate specific instructions, such as stopping or proceeding with caution.
In summary, traffic officers' signals are always executive because they have the authority to regulate traffic and must be obeyed to maintain road safety.
