"The spit dries in our mouths from fear when we pass it," says Mohammad Hussain, who ferries passengers along the road from Kabul to Hazarajat, a region in the central highlands of Afghanistan where the Hazaras have traditionally settled.
Over the years, Hussain says, he has seen the headless bodies of so many people he claims were killed by the Taliban that "I have become ill and have nightmares".
For many, "Death Road" is a symbol of the persecution they have faced for decades.
A recent string of beheadings and kidnappings amid fears over a resurgent Taliban and the rise of the Islamic State group saw thousands turn out in Kabul early this month in protests -- a sight not seen in the capital for many years.

Hussain joined them: "We are being slaughtered like cheap sheep and cows with no consequences... Nobody seems to care about us Hazaras," he tells AFP in Dashte Barchi, a majority Hazara neighbourhood in the outer suburbs of Kabul.
There are no statistics available charting the number of killings that have taken place along "Death Road", but the growing sense of insecurity has seen Mohammad Zaman, who used to drive passengers in and out of Hazarajat, finally admit defeat.
"I gave up driving and sold my car because ... I did not want to witness my passengers being kidnapped or killed again," he tells AFP.
