Transport services in the metropolis and surrounding areas were largely unaffected on the first day of the strike called to demand hike in bus fares in view of the rise in diesel prices and prices of accessories and inputs.
The Transport Minister had earlier refused to accept their demand and warned of strong action in case there was any law and order problem.
Bengal Bus Syndicate, the major bus operators' body, did not join the strike. Taxis and auto-rickshaws were also operating in full strength since morning.
The minister had earlier accused the striking bus operators of working in close concert with the CPI(M), and added that all measures had been taken to avoid any untoward incident.
