Why is there braille on the seat controls of a 18 wheeler?

Question

I understand what the braille is for, but why would it be on an 18 wheeler? I thought there were regulations about driving an 18 wheeler.

Answer 1

Why would there be a need for braille on the seat controls of any vehicle?

Stupid bureaucratic regulations and lack of thought.

Answer 2

Are they 1 bump or 2 bump kind of things?  They might be used for identification without looking at them. Steering wheel controls use this so you can keep your eyes on the road. Look at your keyboard. You may have an index bump on the J key and the F key.

Answer 3

It is not braille, it is just identifying bumps so that you can tell which switch you are pushing without looking.  Although most drivers know which switch they are using just from memory, and what the seat does when they press the switch.  Simple.  It's kind of along the same lines as the bumps on the F and J keys of a keyboard, or the bump on the 5 of a calculator.  They are there, but people rarely use them.

Answer 4

for people that are blind but use ultrasonic frequencies to locate their target, kinda like bats! They scream and listen for the echo. If it takes a while to get back to them, then they are safe. But if they echo comes back quickly, then they know to slow down!! haha

Answer 5

I have checked all over and there is nothing to suggest that any type of braille is used on the seat controls of any vehicle...................

Answer 6

Braille:-unlikely-more prob just grip indentations/bumps or some identifying code for manufacture/assembly, unless the factories use blind workers.
