Before entering a roundabout, what should you do?

Answer: A — Look to the left and right

Before entering a roundabout, you should look to the left and right. This allows you to check for any approaching vehicles and make sure it is safe to enter. Option B, beginning to accelerate, is incorrect as it goes against the general safety precaution of slowing down when approaching a potentially hazardous situation. Option C, coming to a complete stop, is incorrect as roundabouts are designed to keep traffic moving and stopping at a roundabout can cause congestion. Option D, signaling your intentions, is also incorrect as you should only signal when exiting the roundabout, not when entering it.
