Slugging, also known as “Instant Carpooling” or “Casual Carpooling,” is a unique form of commuting that combines ridesharing and hitchhiking. Drivers heading into the city, who want to save time by using the high-occupancy vehicle (HOV) lanes, pick up additional riders, or “slugs,” at a known slug line location. Drivers pull up to the queue for the route they will follow and indicate the drop-off point and how many passengers they can take. Riders fill the car and off they go. In the evening, routes are reversed.  

Rules and Etiquette

No money changes hands between driver and rider, but everyone benefits: the passenger gets a free ride and the driver can use the HOV lane, with everyone reaching their destination much faster than driving themselves.

While it may seem that slugging is a casual way to commute, it is actually very organized with specific pickup and drop-off locations and rules of etiquette that drivers and passengers both follow.  For example, slugs do not talk unless the driver initiates conversation, and there is no smoking or eating by the driver or slug.  For more information, please visit the Slug Line’s website under Rules and Etiquette.
