Explanation:
The question asks about the meaning of a pentagonal-shaped road sign. In the United States, a pentagonal-shaped sign typically indicates a school zone ahead. These signs are used as a warning to drivers that they are approaching an area where a school is located and where children may be present, and thus, drivers should exercise extra caution and be prepared to stop if necessary. Drivers often encounter reduced speed limits and increased fines for speeding in school zones when school zone signs are in effect.
