Government buses were plying as usual even as a section of private buses, lorries and auto-rickshaws kept off the road, police said.
However, call taxi services were being operated normally, they said.
Incidentally, NDA's southern ally PMK had extended support for today's strike, with the party describing it as a 'black legislation' which would affect various stakeholders in the transport sector.
Central trade unions such as All India Trade Union Congress (AITUC), Centre of Indian Trade Unions (CITU), BMS, INTUC, LPF and HMS had made the strike call opposing the NDA government's Road Transport and Safety Bill, 2015.
