Final answer:
California's Basic Speed Law dictates that a driver must never drive faster than what is safe for the current conditions, which requires adapting speed to match road, traffic, weather, and visibility conditions.
Step-by-step explanation:
California's "Basic Speed Law" specifies that you must: C) Never drive faster than is safe for current conditions. This law means you must always adjust your driving speed to match the road conditions, traffic, visibility, and weather, regardless of the posted speed limit. For example, if heavy fog limits your visibility on a highway where the speed limit is 65 miles per hour, you are required to slow down to a speed that is safe considering the current visibility conditions.
Even if the traffic is flowing at a pace above the posted speed limit, it is your responsibility to adhere to the Basic Speed Law and not exceed a safe driving speed. Conversely, if the traffic is moving much slower than the speed limit and driving at the limit would be unsafe due to current conditions, you must slow down accordingly. It's important to note that driving too slow can also be a safety issue and may violate local traffic laws.
This law is enforced to ensure that all drivers operate their vehicles safely, given the varying road and environmental conditions one might encounter while driving.
