The maximum such black corridors were in Tamil Nadu (958), followed by UP (671) and Karnataka (607). Among districts, Viluppuram in Tamil Nadu had a maximum of 70 such corridors.Unlike isolated black spots, these corridors are continuous stretches of NH that have recorded a higher number of fatal and grievous road crashes.
