Primary Route

A Non Primary Route (or Non-Primary Route, sometimes incorrectly called a Secondary Route) is a road that is NOT a Primary Route, and as such is signed with white signage.

The vast majority of roads within the United Kingdom fall into this category. By default, all roads are Non Primary Routes, unless they are added to the Primary Route Network (PRN), which is controlled by the Department for Transport. A local Highway Authority may request addition of a route to the PRN.

There are large numbers of A-class roads that are also Non Primary Routes, whilst the vast majority of B-class roads fall under this category. All Class III (C-class roads) roads and unclassified roads are also Non Primary Routes.
