Can residents ask DfI to introduce yellow-line parking restrictions on their street?

Residents can request yellow-line restrictions, but only DfI can introduce enforceable waiting restrictions on the public road.

DfI normally examines obstruction, visibility, traffic flow, access and parking displacement before deciding whether a legal restriction is justified.

For this type of DfI roads issue, record the exact road name, direction, nearest junction or property and, where relevant, the sign or marking involved. If there is an immediate danger to traffic, prioritise safety and use the appropriate urgent reporting route rather than waiting for a routine roads response. For this question — "Can residents ask DfI to introduce yellow-line parking restrictions on their street?" — that location evidence helps DfI distinguish a general request from a specific road defect or restriction.

For Northern Ireland, this answer has been written around the specific authority that controls the issue — DfI/DVA for roads, parking, testing and licensing, or PSNI/NIRSP for police road enforcement. That matters because guidance copied from Great Britain can use different agencies, forms, procedures or enforcement routes. In relation to "Can residents ask DfI to introduce yellow-line parking restrictions on their street?", that jurisdiction split is part of the answer, not just a source preference.
