• If you intend to exit the roundabout more than halfway
around, use the LEFT-HAND lane.
• If you intend to exit the roundabout less than halfway
around, use the RIGHT-HAND lane.
• If you intend to continue straight through, use either
lane unless signs or markings indicate otherwise.
Navigating Roundabouts
• Move up to the entrance line and wait for a gap in
traffic. DO NOT ENTER next to a vehicle in the roundabout, as that vehicle may be exiting at the next exit.
• Within the roundabout, do not stop except to avoid a
collision; you have the right-of-way over entering
traffic. Keep moving in a counterclockwise direction.
• Do not change lanes in a roundabout.
• A striped channelization island is present in several
roundabouts, which reduces the circulatory roadway to
one lane approaching a single-lane exit.

Well, that was 85 posts ago, so apparently not
