Which vehicle can proceed without stopping at a given situation?

The correct answer indicates that all vehicles—Vehicle 1, Vehicle 2, and Vehicle 3—can proceed without stopping, which typically suggests that there is a traffic control situation or regulation in place that allows for such movement. This might occur in scenarios where all vehicles have the right of way, such as when there are no traffic signals indicating a need to stop, or they are responding to an emergency situation where they are legally permitted to continue through an intersection or designated area without halting.

In various real-world contexts, all vehicles being allowed to proceed without stopping could be due to specific traffic laws, operational protocols for emergency services, or specific instructions from a lawful authority on the scene. This answer emphasizes the understanding of right-of-way rules and situations where traffic regulations permit continuous movement for all vehicles involved.

Consequently, the other options, which refer to individual vehicles, would not encapsulate the notion that all can proceed simultaneously under the right conditions. Each of those vehicles may have specific limitations or circumstances that would not allow them to continue without stopping, unlike the collective understanding depicted in the chosen answer.
