A regulatory sign containing a red circle with a slash through the middle indicates:

  1. That drivers should come to a complete stop.
  2. That an action is forbidden. ✓
  3. That some drivers should yield to other drivers.
  4. That drivers should drive under the speed limit.

Answer: B. That an action is forbidden.

A red circle with a slash through the middle means that an action is forbidden.

Why this is the answer

The Florida handbook describes this as a "NO" symbol: a red circle crossed by a red slash marks something drivers must not do. Regulatory signs set limits or tell drivers what they should or should not do, and the handbook says they are enforceable. That is why this symbol points to a prohibited action rather than to stopping, yielding, or a speed instruction.

Why the other answers are wrong

Remember it

Picture the slash crossing out the action: if it is in the circle, do not do it.
