Drivers and carpoolers have the option of using the I-405 express toll lanes between Lynnwood and Bellevue starting September 27th. Only the new Flex Pass Style will allow you and your carpool partners ride for free on 405.

If you are a carpooler on I-405 and would like to use the new express lanes for free, you’ll need the new Good to Go! Flex Pass.  

To use the Interstate 405 express toll lanes for free, carpoolers will need to activate the new Flex Pass on a Good To Go! Account, then set the pass to HOV mode. The Flex Pass can also be set to TOLL mode when using the lanes as a non-HOV.

(If you already have a Good to Go! window decal and don't plan on carpooling, you can use that to pay for tolls)
