The junction holder is responsible for clearing any snow drifts resulting from highway ploughing that block access to a junction.
The owner of the junction is usually responsible for the junctions of roads other than highways up to the edge of the highway.
According to Section 38 of the Highways Act, parties responsible for the management of private roads and agricultural junctions are obliged to make their junction and maintain it according to the instructions of the road management authority in such a manner as to not constitute a hazard to road safety or an impediment to highway maintenance.
