In what scenario might a bicycle rider be required to yield?

A bicycle rider is required to yield when encountering a vehicle from the right because this follows the general traffic rule that vehicles on the right have the right of way. This is particularly important at intersections where different road users must navigate safe passage. Yielding in such scenarios helps maintain order and prevents accidents, as the bicycle rider must be attentive to the right turning vehicles that may not see them or expect them to be in the right-of-way.

In general, the other scenarios do not universally require a bicycle rider to yield. For example, riding on the sidewalk typically allows the rider to maintain their path unless pedestrians are present. Approaching a stop sign typically requires all traffic, including bicycles, to stop and then proceed once clear, while being in a bike lane often allows cyclists to flow with traffic as long as they adhere to regulations. Each of these situations involves different rules that may not necessitate yielding but rather adherence to specific traffic controls or considerations for other road users.
