What do speed limit signs indicate?
- Potential driving speeds for the area
- The maximum or minimum speed that is legally allowed to be driven ✓
- The speed drivers should drive in heavy traffic
- The speed drivers should drive under poor conditions
Answer: B. The maximum or minimum speed that is legally allowed to be driven
Speed limit signs show the maximum or minimum speed the law allows for that area.
Why this is the answer
The handbook treats a posted speed limit as a legal boundary, not a suggestion. It says your speed must not exceed the posted speed, and it describes speed limits as the fastest you may drive when conditions are favorable. Florida also sets minimum speeds in some places, such as on highways where a 70 MPH limit carries a 50 MPH minimum. That is why the sign can indicate either a maximum or a minimum legal speed, while drivers still must slow down for weather and traffic.
Why the other answers are wrong
- A. Potential driving speeds for the area — Potential driving speeds for the area is too vague; the sign sets a legal limit, not a range of possible speeds.
- C. The speed drivers should drive in heavy traffic — The sign does not tell you a special speed for heavy traffic; you still must stay within the legal limit and adjust to conditions.
- D. The speed drivers should drive under poor conditions — Poor conditions call for driving slower than the posted limit, not for treating the sign as the speed to use in bad weather.
Remember it
Think of the sign as a legal boundary: stay under the maximum, and watch for posted minimums where they apply.
