At present, state governments are empowered to prescribe conditions for the grant of license for public service vehicles, under Section 93 of the Motor Vehicles Act.
"We are working on that (advisory), it will be completed in the next three weeks which will be circulated to the states," a senior Road Ministry official said.
An advisory will be issued to the states on the mobile app-based taxi hailing services, the official added.
In December, the Delhi government had banned all unregistered web-based taxi companies after a driver of Uber was accused of rape. The companies have applied for licences under the radio taxi norms, and continue to ply.
The advisory may be issued as an interim measure till the new Road Transport and Safety Bill is finalised.
The proposed bill is likely to be brought before the Cabinet in the next 10 days after which it will be tabled in the Parliament.
