CHANDIGARH: Despite being completely banned, diesel autos continue to ply on Chandigarh roads while MVI and the traffic police remain silent spectators. Surprisingly, on many routes, hundreds of autos are running without registration and Tamperi numbers. When this reporter asked an auto driver about him driving without registeration, the auto driver replied that he had been driving on Chandigarh roads for the past two and a half years without registeration and proper paperwork. This has been a common site with authorities turning a blind eye to rampant flouting of traffic rules, endagering many lives in the process.
