Passage: "California Vehicle Code section 22350 (the Basic Speed Law) prohibits driving at a speed greater than is reasonable or prudent given weather, visibility, traffic, and roadway conditions, regardless of the posted limit." Based on the passage, a driver traveling at the posted 65 mph limit in heavy fog:

1. Cannot be cited for speed
2. Can still be cited for violating the Basic Speed Law
3. Is exempt because the speed is posted
4. Must be cited under reckless driving only
