3b Secondary Distributor Classified roads (B and C class) and unclassified urban bus routes carrying local traffic with frontage access and frequent junctions Remaining B Roads Defined C Roads Defined Unclassified Link In rural areas these roads link the larger villages and HGV generators to the Strategic and Main Distributor Network. In built up areas these roads are generally link roads with significant bus and HGV usage (typically 75+ per day) and/or carrying local through traffic. They often have 30 mph speed limits and high localised levels of pedestrian activity with some pedestrian crossing facilities including zebra crossings. On-street parking is generally unrestricted except for safety reasons. 4a Link Road Roads linking between the Main and Secondary Distributor Network with frontage access and frequent junctions Defined C Roads Unclassified urban link roads through residential estates and selected rural link roads between villages. In rural areas these roads link the smaller villages to the distributor roads and they can be of varying width and not always capable of carrying two-way traffic. In urban areas they are link roads in residential areas or industrial roads often with 30 mph speed limits with largely uncontrolled parking and random pedestrian movements. They often carry bus traffic and some HGV’s and provide connectivity from the residential 4b estate roads to the main road network. On-street parking is generally unrestricted except for safety reasons.

It is reflective of the nature, location and size of the defect and considers user risk. Cat 1 Safety Critical Defects that present an immediate or imminent risk to the highway user, eg, missing manhole/gully cover, highway collapse. Cat 2 High Defects which may impact on the highway user but are not safety critical, eg, potholes, missing, misaligned or rocking flags/paving units. Cat 2 Medium defects are not required to be urgently rectified and focus more on the serviceability needs of the highway. Cat 2 Low Response of a more routine nature that support the serviceability and sustainability of the highway network.
