The ____ (two words) states that no matter what the posted speed limit, you must travel at a speed appropriate to the conditions.

The phrase "Basic Rule" refers to the principle that emphasizes the importance of adjusting speed according to the specific conditions of the road rather than solely adhering to the posted speed limit. This rule ensures that drivers maintain safety by considering various factors such as weather conditions, visibility, road surface, and the presence of pedestrians or other vehicles.

Even if the posted speed limit is high, if conditions are dangerous—like rain, fog, or heavy traffic—drivers are expected to reduce their speed to a level that is safe for those circumstances. This understanding is vital for promoting safe driving practices and preventing accidents, as it underlines the responsibility of each driver to assess and respond to their environment effectively. Hence, the "Basic Rule" serves as a foundational guideline for responsible driving behavior.
