Can a Class 2 mobility scooter use the road when a pavement is available in Northern Ireland?

The Highway Code says Class 2 mobility scooters should use the footway or footpath when one is available.

Rule 42 distinguishes Class 2 machines, designed for pavement use, from Class 3 road-capable scooters. Where there is no pavement, take particular care if you must use the road, and travel in the direction of traffic where possible. Drivers should allow for the scooter’s low speed. Do not assume every mobility aid has the same road-use capabilities.
