Motorway & GT Road Location Information
Driver location signs, mileposts or mile stones are signs placed every 1 KM along each side of Motorways, and on N5 ( GT Road) to provide information that will allow drivers to know their precise location. These posts are used to help pinpoint road locations for emergency help.
The number for e.g in this posts 432 KM is the distance along the road from a point ( Lahore in this case). The vehicle is 432 KM from Lahore. Many drivers don't know how to convey their location on Motorway Police Helpline (130) when needing *Help*.
In short the counting starts from Lahore 1 and ends in Peshawar 503.
When you enter Motorway from any interchange reset your trip meter to Zero. So you can communicate the distance travel from interchange. Similarly in GT road/ N5 your location is with respect to Karachi
