During a carpool, the driver is called the carpooler but I can't find any words for the passengers who share the same car, how can I call them?

    collinsdictionary.com/dictionary/english/carpooler says carpooler is just "a member of a carpool".

  • Oh my bad, so how can I distinguish the driver and the passengers ?

  • @Kariamoss: You wouldn't usually want to specifically identify one member of a carpool as "the driver" except in contexts where you're only talking about the person driving on one specific journey, since for most people the whole point of a carpool is that by default the members (who must all have cars and be available as drivers) share that role more or less equally. So there can't really be a word identifying the [one and only, permanently assigned] driver since there wouldn't usually be any such person. May 12, 2018 at 13:40
  • @FumbleFingers If you take a presentation about carpool, let's say about blablacar for example, you have to differentiate both because they have a completely different approach of the service.

    On a separate note, the question is phrased as what do you call or how do you say. Ask how do you call and some 7-year-old in the room will respond "with a telephone of course."

To me, and apparently to the compiler of Collins dictionary, a "carpooler" would be a member of a carpool, whether they drive or not. Many carpools are structured so that different people drive on different days.

If a carpool has a single driver you can just say "the driver in the carpool" or "the nominated driver of the carpool". Another phrase is "designated driver", which is often used when a group of people go out drinking, but one chooses to stay sober and drive the others home. Similarly you could say "passengers in the carpool" or "non-drivers of the carpool".

  • What about carpool driver/passenger?

    Sure, I'd understand that.

  • +1 . A carpool is the collective group, of whom the driver is the one driving on that day.

I think you could use either of these:

  • passengers
  • riders

Of those two, I think passenger sounds more formal, and rider more informal.

It’s easy to find dictionary definitions supporting passenger, but finding one for rider was harder to do. I did find one on the Wordnik page:

rider (noun) a traveler riding in a vehicle (a boat or bus or car or plane or train etc) who is not operating it
