57.This section contains transitional provisions which will apply to traffic commissioners and deputy traffic commissioners in England and Wales who are in post when these provisions come into force. In particular, traffic commissioners already in post will remain on their existing terms and conditions of employment, except that they will be subject to the revised terms on dismissal in the amended paragraph 1 of Schedule 2 to the PPVA 1981 (see notes on section 4 above). Similar provisions are made for any existing traffic commissioner for the Scottish Traffic Area. As the appointment and terms of office for any deputy traffic commissioner for the Scottish Traffic Area are not affected by these provisions, no transitional arrangements are required.
