Delhi Autorickshaw Sangh and Delhi Pradesh Taxi Union, which are part of Bharatiya Mazdoor Sangh, said that they are against the bill.
"In the Road Transport and Safety Bill-2014, hefty fines have been proposed for minor traffic violation. Even for a jumping red light, hefty fines would be imposed on motorists which is not fair.
"We will not tolerate this Bill at any cost. We will not let them pass it in the Parliament," Rajender Soni, general secretary of both unions, said.
"If our demand is not met, we would launch a series of protests against the government," he added.
