I attended the consultation meeting for the rewrite of the regulations, which led to lots of wide discussion such as two colours of permits and eligibility, especially for the blind who wish to maintain some independence by travelling with a carer to the shops. They deserve a permit as it is a parking permit rather than a driving permit!
Substantial fines and regular official policing are being considered to address this problem.
One regional city shopping centre has leased its disability parking spaces to the local council for a peppercorn rent. This enables parking inspectors to fine offenders legally. Great idea!
