59. Carpool
A carpool is an arrangement in which people share a car trip while traveling in the same direction. The occupants may share travel costs or simply travel together to reduce the number of separate vehicles making the same trip.
Carpooling is commonly used for commuting, school trips and longer-distance travel. Some road networks provide dedicated carpool parking areas where travelers can meet, leave one vehicle and continue their trip together.

Is carpooling the same as carsharing?
No. Carpooling means several people travelling together in the same vehicle, while carsharing means different users having access to the same shared vehicle at different times.
