Passing Sight Distance

Definition:

It's a term which is used in Highway designing,used only for 2-way 2-lane highways.It's defined as the minimum distance that a driver can make a maneuver (with a slower vehicle in front of him)safely without hitting another vehicle in the opposite direction.

The passing sight distance is prohibited on vertical curves. Solid marking on pavements indicates that no passing is allowed while other dashed white line is used when passing is allowed. Toka.mostafa (talk) 15:31, 25 December 2008 (UTC)
