As the truck, transporting clothes from Kanpur to Delhi, reached Jewar, a heavy vehicle moving ahead suddenly applied brakes, leading to a collision between the two vehicles.
The truck's driver P Yadav and cleaner Pradeep Kumar were rushed to a nearby hospital here where doctors declared them brought dead. Their bodies have been sent for post-mortem.
Yadav was a resident of Mainpuri and Pradeep hailed from Faridabad.
