Paragraph 2 Revision of toll rangesI1

The toll ranges referred to in paragraph 1 shall be recalculated annually on 1 April each year by multiplying the upper and lower limits applying in each toll range by the indexation factor except where a reduction in those limits would result.

The indexation factor shall be derived by dividing the value of the retail prices index for the month of February in the relevant year by the value of the retail prices index for the month of February in the preceding year to produce a percentage and then adding one per cent.
