Can students cross any highway without an escort?

• A. No, they must always have an escort
• B. Yes, but only if using an official traffic control signal
• C. Yes, as long as the bus is nearby
• D. Only if traffic is controlled by a police officer

Answer: (B)

The correct answer is that students can cross a highway only if using an official traffic control signal. This option highlights the importance of safety measures in place to protect children while navigating roadways. Traffic control signals are designed to manage vehicle flow and ensure that pedestrians, including students, can cross safely when it is clear to do so. This ensures that students are following a recognized protocol, significantly reducing the risk of accidents.

In contrast, crossing without such signals would increase the risks, as there may not be proper visibility or control of motor vehicle traffic. The presence of an escort, as mentioned in other options, may not always be feasible or necessary if adequate traffic signals are present. Being near a bus does not inherently provide safety, nor does simply having a police officer present guarantee that students have safe passage. Therefore, having a proper traffic signal in place is a critical factor for ensuring student safety when crossing highways.
