California's Basic Speed Law says you must drive at a speed that is

• A. Exactly the posted speed limit
• B. At a speed that is safe for current conditions
• C. Always faster than other vehicles
• D. At the maximum posted limit

Answer: (B)

In California, the Basic Speed Law means you drive at a speed that is safe for current conditions. The posted speed limit is the maximum you may drive under ideal conditions, but when weather, visibility, road surface, curves, traffic, or other hazards change, you must slow down to a pace that is reasonable and prudent so you can stop or react in time. This means you can be cited for driving too fast for conditions even if you’re under the limit. Aim to adjust your speed to maintain control, keep a safe following distance, and be able to respond to hazards you can see ahead.
