Carpooling, Vanpooling & Slugging
Sharing a ride by carpooling or vanpooling is an excellent way to help reduce traffic and save money at the same time. Many major metropolitan areas have dedicated lanes for high occupancy vehicles (HOV). The advantage given to high occupancy vehicles has spawned a type of ridesharing among strangers called slugging.

Slugging
Slugging is a term used to describe a unique form of commuting found the Washington, DC area sometimes referred to as "Instant Carpooling" or "Casual Carpooling". It's unique because people commuting into the city stop to pickup other passengers even though they are total strangers. However, slugging is a very organized system with its own set of rules, proper etiquette, and specific pickup and drop-off locations.​
