What should you do when approaching an intersection that is blocked by traffic?

When approaching an intersection that is blocked by traffic, stopping before entering the intersection is the appropriate action to take. This is important because it helps prevent gridlock and ensures that vehicles do not become trapped in the intersection while waiting for traffic to clear. Blocking the intersection can cause further congestion and hinder the flow of traffic in all directions, which can lead to accidents or road rage incidents.

By stopping, drivers can assess the situation ahead more clearly and make safe decisions without impeding other road users. This action aligns with the rules of traffic engagement that prioritize safety and the smooth operation of vehicles around the intersection.

The other options may lead to potentially unsafe situations. Accelerating to get through the intersection may cause collision risks if other vehicles are stopped or moving unpredictably. Signaling to change lanes could confuse other drivers and create hazards if the driver cannot complete that maneuver safely. Proceeding cautiously through the intersection without stopping could also create risks of blocking the intersection or colliding with other vehicles or pedestrians. Therefore, stopping before entering the intersection is the safest and most responsible choice.
