A distance board is a roadside sign that tells drivers the distance to upcoming locations, often displayed in kilometers or miles. It helps drivers plan their route and know how far they are from cities, towns, or key destinations. Found along highways, motorways, and major roads, usually after intersections or at regular intervals.
