Florida's basic speed law says that it is illegal to drive at an unsafe speed.

• A. Basic speed law
• B. Speed limit law
• C. Unsafe speed law
• D. Traffic law

Answer: (A)

The basic speed law is being tested here. It requires you to drive at a speed that is reasonable and prudent for the conditions you’re in. The key idea is that you can’t drive at an unsafe speed just because you’re under the posted limit—if weather, road conditions, visibility, or traffic make any speed unsafe, you must slow down accordingly. That’s why this concept fits: it directly codifies that you must adjust your speed to be safe for the actual conditions, not just follow a number on a sign.

This isn’t about the posted speed limit itself, which sets the maximum you may drive under ideal conditions. It’s about driving safely given what’s happening at the moment. The other terms don’t capture that conditional safety requirement in the same precise way.
