The 2010 Equality Act harmonises the provisions of the Disablility Discrimination Act in relation to taxi accessibility.
It provides that a transport service provider and the people who work for it must not discriminate against, harass or victimise any service user because of any protected characteristics (such as race, sex or disability).
The Department for Transport (DfT) published guidance to licensing authorities and the trade on the implications of these taxi provisions on 15 September 2010. That guidance can be accessed via the DfT website.
