Informative signs also called guide signs, are provided to assist the drivers
to reach their desired destinations.
These are predominantly meant for the drivers who are unfamiliar to the place.
The guide signs are redundant for the users who are accustomed to the location.
Some of the examples for these type of signs are route markers, destination
signs, mile posts, service information, recreational and cultural interest area
signing etc.
Route markers are used to identify numbered highways.
They have designs that are distinctive and unique.
They are written black letters on yellow background.
Destination signs are used to indicate the direction to the critical
destination points, and to mark important intersections.
Distance in kilometers are sometimes marked to the right side of the
destination.
They are, in general, rectangular with the long dimension in the horizontal
direction.
They are color coded as white letters with green background.
Mile posts are provided to inform the driver about the progress along a
route to reach his destination.
Service guide signs give information to the driver regarding various services
such as food, fuel, medical assistance etc.
They are written with white letters on blue background.
Information on historic, recreational and other cultural area is given on white
letters with brown background.
