Glossary of London PHV terms
Plain-English meanings of terms used in London private hire licensing, based on the glossary in the TfL handbook, grouped by topic.
The handbook has its own glossary, and it says you will not be tested on the meanings. But understanding the words makes the rest much easier, especially if English is not your first language. This page restates the handbook's definitions in our own words, grouped by topic rather than alphabetically, so related ideas sit together.
