Drivers must yield to pedestrians at unmarked intersections:

Drivers must yield to pedestrians at unmarked intersections because the law places a strong emphasis on pedestrian safety. Unmarked intersections are locations where there are no painted lines or traffic signals indicating where pedestrians should cross; however, this does not diminish the rights of pedestrians. According to traffic laws, pedestrians have the right-of-way in these situations, which means drivers are required to stop or slow down to allow pedestrians to cross safely. This rule is fundamental in promoting cautious driving behavior and ensuring that vulnerable road users, like pedestrians, can navigate intersections without fear of being struck by vehicles.

The other choices suggest conditions or exceptions to yielding pedestrians that are not applicable in law; for instance, a driver must yield regardless of weather conditions or whether the pedestrians are visible. This concept reinforces the necessity of always being aware of and accommodating pedestrians, recognizing that safety is paramount in all driving scenarios.
