While i do think there’s way too many &£&@”@)(!£’s using disabled bays as convenient shortcuts to a parking spot, the blue badge does offer other advantages that we frequently use. Namely, free parking (in some) pay and display areas, and parking on single/double yellow lines (up to three hours in our area).
A quick google didn’t reveal a reason as to why you wouldn’t be allowed to park on single/double yellow lines in Glasgow?
