After slowing to a reasonable speed or stopping, the person shall yield the right-of-way to any vehicle in the intersection or approaching on another roadway so closely as to constitute an immediate hazard during the time the person is moving across or within the intersection, except that a person, after slowing to a reasonable speed and yielding the right-of-way if required, may cautiously make a turn or proceed through the intersection without stopping.
(d) A bicycle operator approaching an intersection shall always yield the right-of-way to any vehicle which has already entered the intersection.
(e) When a bicycle and a vehicle enter an intersection from different roadways at approximately the same time, the operator of the vehicle or bicycle on the left shall yield the right-of-way to the vehicle or bicycle on the right.
