What is the purpose of traffic control signals?

  1. To provide information about local landmarks.

  2. To guide pedestrians on the sidewalk.

  3. To regulate traffic and ensure safety on the road.

  4. To provide directions to drivers.

The correct answer is: To regulate traffic and ensure safety on the road.

Traffic control signals are devices used to regulate traffic and ensure safety on the road. They communicate specific instructions, such as when to go, slow down, or stop, to drivers and other road users. This is essential to keep traffic flowing smoothly and to prevent accidents. The other options are incorrect because they do not directly relate to the purpose of traffic signals. They may serve a secondary function or may occasionally provide information, but their primary purpose is to regulate traffic.
