Driving Around Washington

Ridesharing means riding together in one car or van. Sharing the ride saves money on fuel, insurance, and car maintenance. Ridesharing can also reduce time spent on the road, because vehicles with enough passengers can use High Occupancy Vehicle (HOV) lanes and 495/95 Express Lanes. When they’re not behind the wheel, passengers can read, nap, or chat, reducing stress. Ridesharing also helps reduce air pollution, greenhouse gas emissions and traffic congestion.

Available Services

Ridesharing can be as simple as family members, neighbors, or coworkers deciding to ride to and from work together. But that’s not the only way. Local governments, employers, and private companies offer ridesharing services to match you to an existing carpool or vanpool, or help you form a new one. For instance, in Arlington County, many commercial buildings are required to manage carpool/vanpool incentive programs that offer convenient, reserved spaces and reduced parking rates for ‘pool vehicles. Recently, several companies have begun to offer services that allow users to share rides on an occasional basis—not just for their everyday commute.


The most familiar form of ridesharing, carpooling usually involves a group of people who live and work near each other, commuting together in a private vehicle. Carpool members may take turns driving, and members benefit by not having to drive every day. In some commercial areas, registered carpools get access to convenient reserved parking spaces at reduced parking rates. Although carpooling is usually associated with regular trips to and from work, carpoolers enjoy some of the same benefits when they share a ride to any destination. Increasingly, ridematching services are becoming available that can match drivers and riders for individual trips, not just every-day commutes.


Also known as casual carpooling, is the practice of forming ad hoc, informal carpools for purposes of commuting, essentially a variation of ride-share commuting and hitchhiking. Typically slugging is motivated by an incentive such as a faster HOV lane or a toll reduction. While the practice is most common and most publicized in the congested Washington, D.C. metropolitan area, slugging also occurs in San Francisco, Houston, and other cities. In the Washington area—with the second-busiest traffic during rush hour in the United States and Canada as of 2010—slugging largely occurs on Interstates 95 and 395 between Washington and Northern Virginia. As of 2006, there were about 6,500 daily slugging participants there. While local governments sometimes aid sluggers by posting signs labeled with popular destinations for people to queue at, slugging is organized by its participants and no slug line has ever been created by government.
