As trucks are charging rentals for return load as well, the rentals for essential items like fruits and vegetables have shot up by 75-85 per cent against the rates prevailing till March 15. The rentals have risen despite waiver of toll fee, motor vehicle taxes, deferment of equal monthly instalments on truck loan and third party insurance policy cover on vehicles, according to Mr S. P. Singh, Senior Fellow, Indian Foundation of Transport Research and Training (IFTRT).
