Slugging is a unique form of commuting, different from carpooling, driver and rider(s) are dynamically matched at the slug pickup location based on their destination. Slug lines assists drivers by reaching the two person HOV requirement to avoid tolls, and rider(s) get a free ride. We have about 10,000 commuters along I-95 corridor use this unique form of commuting. With the conversion of I-66 HOV lanes to toll lanes, about 14,000 clean fuel vehicles lost their exemption to travel on I-66 during peak hours. After a month of coordination and communication with I-66 commuters, we came up with few accessible pickup locations. We still have to run it through the local government and other organizations. Most of the afternoon slug lines are co-located with the existing slug lines in DC. Slug lines grow organically and depending on the demand and convenience locations may be added or modified by the commuters.

How do they work?

  • The driver pulls into one of the many known locations for Sluglines, where riders line up
  • The driver holds up a SIGN or rolls down the window to CALL OUT his/her destination.
  • Riders first in line heading to the driver’s location get into the car and off they go!
