One Way Random Thought

I was downtown earlier today.  As you know with downtown Amarillo you will find a lot of one way streets.

So I am sitting at a stop sign on a one way street and I looked both ways before I drove through.

Hmmm...so my question is, Is it normal to look both ways on a one way street since traffic only goes one way.

I guess it is just habit to look both ways before crossing the street.
