A Flex Pass is a kind of Good To Go! pass designed for people who carpool in the I-405 express toll lanes or the SR 167 HOT lanes.
It works on every toll road in Washington and gives you the most flexibility of all our passes. Not only can you use it to pay tolls, it also gives you the option to carpool for free on the SR 167 HOT lanes and the I-405 express toll lanes (see carpool rules).
When are tolling hours?
Tolls are only collected at the following times. Everyone can drive for free (no pass needed) at all other times:

How does it work?
The pass has a slider, allowing you to switch between TOLL mode and HOV mode. When you have enough people in the car to travel toll-free in the I-405 express toll lanes or the SR 167 HOT lanes, switch the pass to HOV mode. If you don't qualify to ride toll-free, set your pass to TOLL mode to pay your toll at the lowest rate.
What about other toll roads?
A Flex Pass set to HOV or TOLL mode will allow you to pay your toll at the lowest rate on the SR 520 and Tacoma Narrows bridges. Carpools do not travel for free on these toll roads, so it doesn't matter in which mode your Flex Pass is set.
What are the other pass options?
If you’re not carpooling on I-405 or SR 167, then you can use a sticker pass. It works to pay tolls on every toll road in Washington.
Motorcycles should get a Good To Go! motorcycle pass.
