True or False: A blue sign with white letters indicates a recreational area or park.

A blue sign with white letters typically does not indicate a recreational area or park. In the context of road signage, blue is generally used to signify services such as rest areas, hospitals, or lodging. While parks or recreational areas may use blue signs in some instances, the color convention for parks usually includes green for public parks, brown for recreational areas, and other specific colors that denote specific types of facilities. Consequently, saying it is false that a blue sign with white letters indicates a recreational area or park reflects the accurate understanding of the color coding system used for road signs. This knowledge is essential for drivers to interpret signs correctly and navigate appropriately.
