pit stop?

Is a pit stop the same thing as a rest stop (like on the freeway)?

Racing drivers take pit stops during a race to change tyres and fix anything that's broken. The expression can also be used when I person has a rest or break etc.

Eg: "I think it's time for a pit stop after this, and then we'll get cracking with the other side" .

Ben.

How about "pit stop town" and "rest stop town"? Do they both mean a town where you can take a rest during a long drive on a freeway / highway...? (Like they are synonyms to each other?)

Well, those would probably apply to towns that just on the way to somewhere else, when you can stop and go to the bathroom. I've never heard those phrases before, but that's what "making a pit stop" often refers to -- answering the call of nature.
