What is the fundamental speed law?

The fundamental speed law emphasizes the importance of driving at a speed that is safe for the current conditions, regardless of the posted speed limit. This means that drivers must assess factors such as weather, visibility, road conditions, and traffic when determining an appropriate speed. For instance, during poor weather conditions such as rain or snow, even if the speed limit allows a certain speed, it may still be unsafe to drive that fast.

This law promotes safety and responsible driving, ensuring that all road users adjust their speed accordingly to minimize the risk of accidents. It establishes that the posted speed limits are maximum allowed speeds under ideal conditions, and drivers must always prioritize safety by modifying their speed as necessary.

In contrast, the other options focus either on specific speed limits or rigid standards that don’t account for varying conditions, which could lead to unsafe driving practices.
