US State Department Travel Warnings & Consular Information Sheets Pakistan - Consular Information Sheet http://travel.state.gov/pakistan.html December 12, 1997
Road
Travel: Road travel in Pakistan is risky. Roads are crowded,
drivers are aggressive and poorly trained, and many vehicles,
particularly large trucks and buses, are badly maintained. In
addition, roads, including major highways, are poorly maintained
and often have numerous potholes, sharp drop-offs and barriers
that are not sign-posted. Driving without experienced local
drivers or guides is not recommended. For specific current
information on road conditions along the Karakoram Highway,
travelers may contact the Frontier Works Organization in
Rawalpindi at tel. 92-51-566639.
