# Directive 1999/62/EC of the European Parliament and of the Council of 17 June 1999 on the charging of heavy goods vehicles for the use of certain infrastructures, Division 4: Share of goods traffic, equivalence factors and correction mechanism

Extent: E+W+S+N.I.

The calculation of tolls shall be based on actual or forecast HGV shares of vehicle kilometres adjusted, if desired, by equivalence factors, to make due allowance for the increased costs of constructing and repairing infrastructure for use by goods vehicles.
The following table gives a set of indicative equivalence factors. Where a Member State uses equivalence factors with ratios differing from those in the table, they shall be based on objectively justifiable criteria and shall be made public.
See Annex IV for the determination of the vehicle class.
The vehicle classes correspond to axle weights of 5,5, 6,5, 7,5 and 8,5 tonnes respectively.

Tolling regimes which are based on forecast traffic levels shall provide for a correction mechanism whereby tolls are adjusted periodically to correct any under or over-recovery of costs due to forecasting errors.
