What does this blue service sign with a white Rx symbol tell you?

The blue services family uses a white H for a hospital. The white Rx square marks a pharmacy, not an emergency department. This answer groups every blue medical service sign under one label because the white H and the white Rx share the same blue background.

First-aid stations carry their own service pictograph; the blue Rx square marks a pharmacy service. This answer treats every roadside medical service as interchangeable, so a first-aid station gets matched to whichever medical symbol the driver spots first.

The Rx pictograph marks a pharmacy that fills prescriptions, not a shop that merely sells over-the-counter remedies. This answer reads the everyday word 'drugstore' as a plain synonym for pharmacy, so a corner shop stocking aspirin looks as if it should earn the sign.
