Found this on another Q/A site:
''This is what the Highway Code says:
DO NOT stop or park:
- where the kerb has been lowered to help wheelchair users and powered mobility vehicles
- in front of an entrance to a property"
This is not a law, it is a rule in the highway code, and failure to comply with this rule, will not, in itself, cause a person to be prosecuted, however, it can be used in evidence in any court proceedings under the Traffic Acts.''
