What are the yielding rules when entering and exiting a roundabout?

[McJasper]

The driving rules for roundabouts are as follows: 1. Incoming yields to outgoing: Vehicles entering the roundabout must yield to those exiting. 2. Outer yields to inner: Vehicles on the outer lane must yield to those on the inner lane. 3. Turning yields to going straight: Vehicles making turns must yield to those going straight. 4. Orderly sequence, small yields to large: Rear vehicles must yield to front vehicles, and smaller vehicles must yield to larger ones. 5. Use turn signals: Before entering the roundabout, if a vehicle intends to enter the left lane inside the roundabout, it should activate the left turn signal to alert other vehicles; before exiting, the vehicle should signal right in advance, confirm safety, and then change lanes from the inner lane to exit the roundabout.
