Why do drive-thru ATM machines have Braille numbers and instructions?

Asked by Buttonstc (27605) October 5th, 2014 from iPhone

For whom do they expect this to be necessary?

Obviously it’s very helpful for ATMs located in stores or banks.

However, if you’re a person who needs Braille, then you shouldn’t be driving a car, obviously.

So what’s up with this? Is this one of those government mandated things regardless of common sense, or what?
