Image description: large circle (button?) With a symbol of a person holding a cane. Underneath, the word "stop" is written in braille.

It says "stop" =)

Commonly on buses you'll see the stop button with just the letter "s" in Braille.

Is it at an intersection? Could it be for stopping traffic?

Is it at a bus stop, and used to stop a bus?

Or in a bus to let the driver know you want to stop?

wish we had that stuff here.
Where I live they have only one accessibility feature and that is being able to slightly tilt the bus so that weelchare users can get in. Gotta say tho they do that for blind people too and it really helps sins my guide dog is getting old.
So i just shout tru the buss is there anyone who can ring the bell for me pleas.
Best reaction i had was a few people starting to sing ring my bell.
