You are giving way at a roundabout and the vehicle in front of you also gives way. Once the vehicle in front enters the roundabout, can you follow it in immediately?

1. Yes — the vehicle ahead gave way on your behalf
2. Yes — following traffic in a roundabout gives you automatic clearance
3. No — you must independently check it is safe before entering and give way to all roundabout traffic yourself
4. Yes — as long as you maintain a 2-second gap from the vehicle ahead
