What action should you always take when entering an intersection?

Answer: A — Stop and then proceed when safe

When entering an intersection, you should always stop and then proceed when safe. This is important because it allows you to assess the situation and make sure it is safe before entering the intersection. Yielding to all traffic (B) is also a necessary action, but it may not always be applicable depending on the specific intersection. Speeding up for a quicker crossing (C) is never a safe or legal option as it increases the risk of accidents. Stopping in the middle of the intersection (D) is also not a safe option as it can block oncoming traffic and create a hazardous situation.
