You are approaching an uncontrolled intersection. What should you do?

Answer: C — Look to your left before entering

When approaching an uncontrolled intersection, you should look to your left before entering. This is because an uncontrolled intersection does not have traffic signs or signals, so you need to be aware of any oncoming traffic from your left side before proceeding. Option A is incorrect because you may not need to come to a complete stop if there is no traffic. Option B is incorrect because honking your horn may startle other drivers and cause confusion. Option D is incorrect because a slow roll may not give you enough time to react to any oncoming traffic. Overall, it is important to always look both ways and proceed with caution at an uncontrolled intersection.
