Which statement describes the basic speed law in California?

• A. The speed limit is the maximum allowed under ideal conditions; adjust for weather, visibility, and traffic.
• B. You should always drive at the posted speed regardless of conditions.
• C. The faster you drive, the safer you are.
• D. You must always drive exactly at the posted limit.

Answer: (A)

You must drive at a speed that is safe for current conditions. The posted speed limit is the maximum you may drive under ideal conditions, but you must adjust your speed for weather, visibility, and traffic. This means slow down in rain or fog, on wet or icy surfaces, or when visibility is reduced, and only drive at the limit when conditions are clear. The statement mirrors that idea by tying the limit to ideal conditions while emphasizing the need to adjust for real-world conditions. It’s not about always hitting the posted limit, never about going faster than safe, and not about driving exactly at the limit regardless of conditions.
