• As you approach, scan for pedestrians and cyclists at the crosswalks at the entrance and exits of the circle.

And with respect to two-lane roundabouts (p. 63):

When you intend to exit at the first available exit:
• Approach the circle using the right lane.
• Use your right signal as you approach. Leave it on until you have exited the circle.
• As you approach, scan for pedestrians and cyclists at the crosswalks at the entrance and exits of the circle.
• Yield to traffic in the circle.
• Exit the circle using the right lane.

When you intend to leave at any other exit:
• Approach the circle using the left lane.
• Activate your left signal to communicate that you do not plan to use the first exit.

If you signal your intent a person at the next exit who would ostensibly have to yield to you because you're to their left can know whether:

1. if you're signalling left, you're going past the first exit, and the person needs to yield to you, or
2. if you're signalling right, you're going to get off at the next exit, and the person can enter the roundabout

If you don't signal your intent when you approach the roundabout that person to your right is left guessing WTF you're going to do, and if they're driving defensively ought to just sit there and wait for you to do WTF you're going to do. If you're just getting off at the first exit and don't signal when entering the roundabout they have to unnecessarily wait when they themselves could have just gone without having to stop for you. Surely you can see how this pisses other people off...?

Unless I'm misunderstanding your answer, Swift and I are talking about approaching to enter the roundabout and not approaching the exit of the roundabout. The quotes from the guide you selected are about signaling when approaching the exit of the roundabout.

Edited to add the complete selection from the guide on p63 - your snippet left out the context of approaching. Nowhere in the sections about entering a roundabout does it make mention of having to signal.

Two-lane traffic circle /
roundabout

Entering circular intersections:

Drivers entering the circular intersection
must yield to drivers already in the circle.
Once in the circle, drivers must activate
the right signal when preparing to exit.

Using the right lane to enter and exit:

Drivers entering the circle from the right
lane must do so when it is safe and stay
in the right lane while in the circle. They
must exit using the right lane.

Using the left lane to enter and exit:

Drivers using the left lane to enter the
circle must do so when it is safe and
stay in the left lane while in the circle/
roundabout. They must exit using the left
lane. Drivers planning to travel past the
first exit should use the left lane to enter
and exit.

In circular intersections:

While in the circle, the drivers on the
right must yield to the drivers on the left.
Activate the right signal when preparing
to exit. Use caution when exiting and
crossing through the right (outside) lane.
