Sounds like she should be allowed to park there.

Parking on the pavement is not illegal outside London and Scotland, though drivers can be fined for blocking pedestrian access or obstructing traffic flow.

Oh great!

It is an offence under the Highways Act 1980 to drive across a pavement to access private land without a properly constructed dropped kerb.

This doesn't make sense to me. Why can you park on the pavement but not cross the pavement to your driveway. Surely people should encouraged to park their cars off the street and especially pavement.
