A carpool is a transportation arrangement where multiple people share a vehicle to travel together to a common destination. This practice helps reduce the number of cars on the road, which can lead to less traffic congestion and lower fuel costs for each participant. Carpooling is often organized among coworkers, friends, or neighbors who have similar schedules. In addition to saving money and reducing environmental impact, carpooling can also provide social benefits. Passengers can enjoy conversations during the ride, making the journey more enjoyable. Many cities and organizations promote carpooling through dedicated lanes, apps, and incentives to encourage more people to participate.
