The Lowari Pass begins in the town of Dir in the tribal regions of northwest Pakistan. The road is 240km long and is the only supply route through the mountains to the small villages of the Chitral valley which is shared with Afghanistan. It is a road where even the slightest error can be fatal.The holy city of Dir and its 20,000 inhabitants make their living off the road. Each day tons of goods are loaded and unloaded from trucks, the only means of transport in the region. The trucker's quarter provides most of the jobs here. Drivers, mechanics, assistants of all ages work here every day amid the dust and pollution.We follow Pakistani truck drivers facing death at every turn transporting goods across mountain passes on arguably the world's most dangerous road.
