Slugging From Stafford: How Casual Carpool Lines Work

Quick answer: Slugging is free, on-the-spot carpooling. A driver who needs riders to reach the HOV-3 minimum pulls up to a slug line and calls out a destination, and the first riders in line get in (Slug-Lines.org). In Stafford, the main morning line forms at the Route 610 Staffordboro commuter lot off Garrisonville Road.

If you're moving to Stafford and work in Arlington or D.C., slugging may be the cheapest way up I-95. It costs nothing, it uses the Express Lanes and it runs on unwritten rules that regulars take seriously. Here's how it works, where the lines are and what to know before your first morning.

How slugging works

OmniRide describes slugging as casual carpooling: drivers pick up enough passengers going to a specific destination to use the Express Lanes without paying a toll. No money changes hands. The driver gets a faster trip and the riders, called slugs, get a free one (OmniRide).

The Express Lanes are free for vehicles with 3 or more people when the driver's E-ZPass Flex is set to HOV ON. The operator warns that Virginia State Police can issue tickets of up to $1,000 to drivers who claim HOV without the headcount (Express Lanes). That's why a solo driver needs two slugs, not one.

At the line, the driver either shows a sign or calls out a destination such as "Pentagon" or "14th and New York." The first riders waiting for that destination get in and confirm the drop-off point (Slug-Lines.org). Slug-Lines.org is a volunteer guide rather than an official agency, so treat its times as rider reports.

Where the Stafford lines form

Route 610 (Staffordboro). OmniRide lists the Staffordboro/Route 610 lot with 1,865 spaces, slug lines and service from routes 942 and 943 (OmniRide). Slug-Lines.org says slugs stand near the bus shelter in the center of the lot and that drivers head to the Pentagon, Crystal City, Rosslyn and 14th Street. It lists 5:45 to 7:30 a.m. as the best window and says the lot is generally full by 6:45 a.m., after which drivers and slugs shift to the Mine Road lot (Slug-Lines.org). GWRideConnect lists both the Staffordboro north lot and the Mine Road south lot on Route 610 (GWRideConnect).

Route 17 (Falmouth). Slug-Lines.org describes a line at the Route 17 commuter lot north of I-95 Exit 133B, behind the bus shelter, with rides to the Pentagon, 14th Street, Crystal City and Rosslyn from 5:30 to 8:30 a.m. (Slug-Lines.org). OmniRide's lot table shows no slug line at its Falmouth Route 17 listing (OmniRide). When the two sources disagree, I'd go see it on a weekday morning before you count on it.

Route 630 (Courthouse Road). OmniRide lists the Route 630 lot with no slug line, served by route 541 (OmniRide). It's a bus lot more than a slug lot in the morning.

Slug line etiquette

Slug-Lines.org's etiquette list covers the basics (Slug-Lines.org):

• First come, first served. Don't jump the line unless a driver calls you by name.
• Keep conversation light and let the driver start it. Skip sensitive topics.
• No money or gifts, no eating and no smoking in the car.
• Buckle up, ask before changing the radio or temperature and keep phone calls short.
• Drivers pick up only at the designated line, not along the main road.
• Either the driver or the rider can decline a ride.

The ride home

Evening lines form near the workplaces. At the Pentagon, Slug-Lines.org describes lines near Fern Street in South Parking and in the "Pork Chop" area off South Rotary Road, with rides to Route 610, Route 630 and Route 17 in Stafford. It lists the earliest pickups at 1:00 p.m., the peak from 3:00 to 6:00 p.m. and the latest around 7:30 p.m. (Slug-Lines.org).

Locations can move. In 2025, the Pentagon's transportation office shifted the evening Route 610 pickup during security fence construction on North Rotary Road (Slug-Lines.org). Check the current spot before your first evening, and keep a backup plan such as an OmniRide bus.

What this means when you buy in Stafford

If slugging is your plan, the drive to the lot matters as much as the drive to work. North Stafford around Garrisonville and Aquia puts you close to the Route 610 lots, while south Stafford and Falmouth are closer to Route 17. Do a test run at the hour you'd really leave. My VRE vs. Express Lanes commute guide compares the other options, and my Quantico commute guide covers the trip north on Route 1 and I-95.
