Who enforces yellow-line parking restrictions in Northern Ireland?

Most decriminalised yellow-line parking restrictions in Northern Ireland are enforced by DfI traffic attendants, while PSNI retains responsibility for criminal road-safety offences and police directions.

A Penalty Charge Notice can be issued where a vehicle contravenes an enforceable waiting restriction. Always check signs, kerb markings and any local exemptions.

For parking questions, the exact sign, road marking, kerb marking and hours of operation control the answer at the location.

For "Who enforces yellow-line parking restrictions in Northern Ireland?", those details are especially important because the same road can have different rules by bay, side, time or vehicle class.
