Can traffic officers use both optical and acoustic signals to direct traffic?

Question

DentroTest · Accepted Answer

Yes, traffic officers have the highest authority on the road and are empowered to use both optical signals (arm movements, lights) and acoustic signals (whistle use) to regulate traffic. For example, short and frequent whistle blasts order vehicles to stop, while a long blast orders them to resume driving. Therefore, they are not limited to just one type of signal.
