Cars such as Toyota Etios, Maruti Omni, Mahindra Logan, Tata Indica and Tata Indigo are fairly popular among taxicab operators. The livery of the taxicabs in India varies from state to state. In Delhi and Maharashtra, most taxicabs have yellow-black livery, while in West Bengal, taxis have yellow livery. Private taxicab operators are not required to have a specific livery. However, they are required by law to be registered as commercial vehicles.
