directional sign
A posted indicator showing or confirming the route to a particular destination, often with arrows or instructions.
A directional sign is a posted indicator of the correct route to any particular place, often accompanied by arrows or instructions.
The sign relates the traveler's route to a destination. An arrow is common, but written instructions or another posted indication can also provide the direction.
A traffic signal issues changing commands about movement. A directional sign gives route guidance rather than alternating permission to proceed or stop.
