How does it work?

(It's as easy as 1, 2, 3)

1

Pick your line.

Head to a designated slug line in the morning or afternoon.

2

Match up.

Drivers call out their destination or display a sign; first in line for that destination hops in.

3

Go!

Once the car meets HOV-3+ and the driver’s E-ZPass Flex is switched to HOV ON, head to the I-66 Express Lanes. It’s fast, free, and efficient.

Respect the community.
