What does California's "Basic Speed Law" state?

The correct choice outlines the essence of California's "Basic Speed Law," which emphasizes that drivers must not exceed a speed that is safe for the specific conditions at any given time. This law recognizes that various factors, such as weather conditions, traffic, road conditions, and visibility, can influence what is deemed safe. Therefore, a speed limit may not always represent the maximum safe speed under all circumstances. For instance, in rainy conditions or heavy traffic, driving at or above the posted speed limit might be unsafe, making it vital for drivers to adjust their speed accordingly to ensure safety.

Understanding this law helps drivers remain adaptable and focused on safety rather than merely adhering to set speed limits, which may not adequately account for real-time road conditions.
