if you are disabled and fit to work you do not get a blue badge, also a lot of blue badges are fakes, and a lot of sad healthy people use there grandparents badges because they are lazy then you get the moronic people like jo-90 that just the disabled spaces
Of course u get a blue badge if you are registered disabled. thats my point, the disability discrimination act tells us they should be equally treated, yet in most places they park for free when they could be working full time.
You are right about family members using the badges though.
