single yellow line with kerb markings ,bryn st

can you park on any single yellow lines with kerb markings on them if you have a blue badge ? . on bryn st in ashton they have these markings outside boutique dentist & across the road . iv,e google earthed bryn st & the post has 2 plates on it , 1 with yellow background with blue trim & another white . both display times but it only adds to the confusion ? . iv,e asked several people & even the council & i cant get any sense out of any of them ? . does anyone know ? .

As far as I know you can park there with a blue badge for up to three hours.
