Slugging – or Casual Carpooling

There's a popular form of casual carpooling in the region known as slugging. To take advantage of faster commute times in the Express Lanes, commuters form on-the-spot carpools. Drivers simply pick up enough passengers going to a specific destination to use the Express Lanes without having to pay a toll. No money is exchanged yet everyone wins because the driver has a faster commute and the passengers get a FREE ride.

Slugs typically catch rides at local commuter lots and at or near major employment sites in Washington, D.C. and Northern Virginia. Visit or for more information.
