The process
How Slugging Works
Slugging is Northern Virginia's unofficial carpool system. Drivers get the riders they need for HOV-3, and riders get a free commute to a shared destination.
What is slugging?
A simple three-part exchange
The original Sluglines site explained the flow with real commuter photos. This version keeps that same authenticity and makes the process easier to scan on phones and desktops.
Match destination
Drivers call out or display their destination.
Ride together
Riders heading that way get in and everyone saves time.
01
Go to a Slug Line Spot
Head to one of the designated pickup locations across Northern Virginia. Riders form a line and wait quietly.
02
Driver Announces Destination
A driver pulls up and announces their destination, either with a sign or by calling it out. Riders at the front of the line for that destination get in.
03
Fill the HOV-3 Requirement
The driver picks up 2 riders to qualify for HOV-3 status. All three now have access to the express lanes.
04
Drop Off at Destination
Driver drops riders at the agreed-upon location. No money exchanged, ever. Everyone saves time.
Common Questions
Is slugging safe?
Slugging has run in Northern Virginia since 1975, when the first HOV lanes opened on I-395. It is informal and self-governed: nobody screens drivers or riders, and both are free to pass on any ride they are not comfortable with.
Do I need to register or pay?
No. Slugging is completely free and informal. No money is ever exchanged between drivers and riders.
What are the peak hours?
Weekdays, 5:30–9:30 in the morning from the suburbs toward DC, and 3:00–7:00 in the afternoon from DC back out.
Can I request a specific route?
Riders take the first car heading to their destination. Drivers call the destination, and the line moves in order.
