Usually, taxis have yellow registration plates with black script written on it
(TYPE 1 - Refer illustration above) but off late, I've been seeing many tourist taxis (especially high end ones like Mercs, Camrys, Corollas, NHCs etc.) with black registration plates with yellow script
(TYPE 2- Refer illustration above).
Has there been any change in the regulation?
If yes, is it made to distinguish tourist taxis from regular intra-city taxis and embassy vehicles (which also have yellow plates with black script)?
