Roundabouts in BC

Correct me if I’m wrong, but from what I understand, a driver does not need to signal to enter a single-lane roundabout; it is only necessary to yield to traffic already in the roundabout when entering.  When entering the roundabout there is no other way to go but to the right so signalling entry is not necessary.
 
According to this government site, it appears you only need to signal to exit a single-lane roundabout. Even though you will be exiting, again to the right, it lets the other drivers know which exit you are taking.
