Answer: D — Stop before entering the intersection and wait until traffic ahead moves on

You should always stop before entering an intersection when the roadway ahead is blocked with traffic, as it can be dangerous to proceed further. Option A suggests continuing into an intersection without a clear path, which can be risky and potentially lead to an accident. Similarly, keeping as close as possible to the car ahead (Option B) can increase chances of a collision if traffic suddenly stops. Honking the horn (Option C) may also be risky as it can startle other drivers and potentially cause a crash. Therefore, the safest course of action is to wait and observe until the traffic ahead clears before proceeding into the intersection.
