Do I Need Good To Go! for Washington? 2026 Update

No — but you'll pay $2 more per trip without one. Washington operates 5 all-electronic toll facilities with Good To Go! providing the lowest rates and fastest passage. All facilities are cashless.

Key Reality: Without Good To Go!, you pay Pay-by-Mail rates — $2.00 higher per trip than the Good To Go! rate at SR 520, SR 99, and Tacoma Narrows. For daily commuters, this adds up to $500+ per year. HOV 2+ with Good To Go! rides I-405 and SR 167 Express Lanes free.

2026 Update: E-ZPass is not accepted in Washington — Good To Go! is the only accepted transponder system. Washington state joined E-ZPass as an accepted tag in Florida and Minnesota (those states now accept Good To Go!) but Washington itself still uses only the Good To Go! system domestically. Motorcycles ride all Washington toll facilities free regardless of payment method.
