Quite often even if it has expired but you display it the correct way up it looks less suspicious and plods dont bother looking at the expiration date. My mother had to do this on a few occasions because despite applying for her renewal on her blue badge 8 weeks in advance of the expiration date (when she was told to) and being approved it still took 12 weeks for it to be delivered.

And when you get your new one they tell you to send your old one back because they know Plod doesnt bother reading expiration dates also.
