If people carpool, they travel together to work or school in one car and share the cost, instead of each person driving alone. The word is also a noun: a carpool is the group, or the arrangement. It is everyday English, especially in American use; in Britain people more often say lift-share or car-share, though carpool is widely understood. It feels practical and a little informal — workplace posters and family chat, not courtroom language. Pool here has nothing to do with a swimming pool; it means putting something into a shared pot.
