Curbs painted yellow indicate:

  1. Designated free parking areas.
  2. Paid parking areas.
  3. No parking zones. ✓
  4. Optional parking areas.

Answer: C. No parking zones.

Curbs painted yellow mean no parking zones.

Why this is the answer

The Florida handbook lists yellow painted curbs among the places where you may not park, and it explains that curbs are often marked yellow to show no parking zones near fire hydrants or intersections. So a yellow curb is a stopping restriction, not a place to leave your car. Nothing in the handbook describes yellow curbs as free, paid, or optional parking areas.

Why the other answers are wrong

Remember it

Think of yellow at the curb as a warning to keep moving, the same way yellow means general warning on signs.
