What is car pooling

Carpooling is the shared use of a car by the driver and one or more passengers.
Carpooling arrangements and schemes involve varying degrees of formality and regularity.
Carpoolers use pool member's private cars, or a jointly hired vehicle, for private shared journeys.
Carpooling reduces the costs involved in repetitive or long distance driving by sharing cars, sharing rental charges, or paying the main car owner.
Some countries have introduced high-occupancy vehicle (HOV) lanes to encourage carpooling and use of public transport, to combat rising traffic congestion.
In reducing the number of cars on the road, carpooling decreases pollution and the need for parking space, and in a global perspective, reduces greenhouse gas emissions.
Shared driving carpooling can also reduce driving stress.
In some cases, companies or local authorities will introduce facilities to encourage private carpooling, often as part of wider transport programs. These can include central listing facilities, defined pick-up points, preferential parking and general advice.
