For which of the following reasons should speed be reduced below the posted limit?

Reducing speed below the posted limit is essential for several safety reasons, especially in situations like driving in unfavorable weather conditions and when approaching intersections.

Driving in adverse weather conditions—such as rain, snow, ice, or fog—can significantly affect vehicle handling and stopping distances. Slippery roads can require longer stopping distances, making it crucial for drivers to adjust their speed accordingly to maintain control and ensure safety.

Approaching intersections also warrants a reduction in speed. Intersections are high-traffic areas where the probability of encountering pedestrians, bicycles, and other vehicles increases, along with the risk of accidents. Slowing down allows drivers to react quickly to any potential hazards and makes it easier to gauge the actions of other road users.

By recognizing both scenarios as critical for safe driving practices, it's clear that adjusting speed based on conditions and surroundings is vital for ensuring the safety of oneself and others on the road.
