The concessions mentioned in subsection (2) shall apply in respect of vehicles lawfully displaying a recognised badge as they apply in respect of vehicles lawfully displaying a badge issued under section 21.
The concessions are—
any exemption from an order under the Road Traffic Regulation Act 1984 given by reference to vehicles lawfully displaying a badge issued under section 21;
any provision made in an order under that Act for the use of a parking place by such vehicles.
The appropriate national authority may by regulations provide that recognised badges are to be treated, for purposes specified in the regulations, as if they were badges issued under section 21.
