What does the panel with the inclined arrow signify on a direction sign?

The panel with the inclined arrow signifies that a destination can be accessed by taking an exit from the motorway. This indicates to drivers that they have the option to leave the main roadway to reach a particular destination, such as a town or service area. The use of an inclined arrow visually communicates the direction in which drivers should travel to reach the exit, helping with navigation and ensuring that the route is clear.
