. The essence of the systems is the use of a meeting-place to form carpools, without any advance contact between the participants. For people wishing to carpool, going to a meeting place is a very low-effort method for getting into a carpool, compared with any other system that involves contacting potential riders or drivers in advance, and arranging the trip. The key is that other people are also coming to the meeting place, and there need to be sufficient people traveling from any one meeting-place to the common destination so that the waiting time to form a carpool is acceptable. Slug lines are generally organized and maintained by volunteers, although there has been government involvement in organization as well.

, first appearing in the Washington (D.C.) Metropolitan Area in 1975. The failure of the new lanes to relieve congestion, and frustration over failures of public-transport systems and high fuel prices, led to the creation in the 1970s of "slugging", a form of hitchhiking between strangers that is beneficial to both parties, as drivers and passengers are able to use the HOV lane for a quicker trip. While passengers are able to travel for free, or cheaper than via other modes of travel, and HOV drivers sometimes pay no tolls, "slugs are, above all, motivated by time saved, not money pocketed". Concern for the environment is not their primary motivation. In the Washington area, slugging occurs on Interstates 95, 66 and 395 between Washington and

Etymology

The term ''slug'' (used as both a noun and a verb) came from bus drivers who had to determine if the people waiting at the stop were genuine bus passengers or merely people wanting a free lift, in the same way that they look out for fake coins—or "

General practices

In practice, slugging involves the creation of free, unofficial ad hoc carpool networks, often with published routes and pick-up and drop-off locations. In the morning, sluggers gather at local businesses and at government-run locations such as

—the largest place of employment in the United States, with 25,000 workers—is a popular destination. Enough riders fill the car and the driver departs. In the evening, the routes reverse. Many unofficial rules of etiquette exist, and websites allow sluggers to post warnings about those who break them. These include: * The slug first in line gets the next ride to their destination and also gets to choose the front or back seat. Slugs should never take a ride out of turn. * Drivers are not to pick up sluggers en-route to or standing outside the line, a practice referred to as "body snatching". * A woman is not to be left in the line alone, for her safety. * No eating, smoking, or putting on of makeup is allowed. * The driver has full control of the radio and climate controls. * Windows may not be opened unless the driver approves. * No money is exchanged or requested, as the driver and slugs all benefit from slugging. * Driver and passengers say "Thank you" at the end.
