Not sure why anyone would not get Real ID. Bringing the passport along all the time seems like an unnecessary aggravation. Bringing it one time to DMV when you get your Real ID. Too easy.
Because some of us, like
@GariYaMoshi and myself, already have handy alternative ID, NEXUS card for me and Passport card for Gari. We will not need to carry passport or a Real ID DL to clear TSA even after May 2025.
Getting an Enhanced Driver's License, the only Real ID compliant license Washington offers, is a pain. It would require an in person appointment with the Department of Licensing, documentation, and paying $7 extra per year for the remaining years on my current license to upgrade, plus increased fees to renew it. My last renewal was valid for 8 years. I think EDLs can only be issued for 5 max, so I might get three years cut off my current license in the bargain.
The two reasons to get an EDL here are to cross into Canada without a passport and clear TSA after May. I can do both with my NEXUS, which is always in my wallet and which I've used instead of my DL at TSA checkpoints for many years now anyway. I don't need another piece of ID to do the same exact things. My current regular license is valid through 2031, and I haven't seen the inside of a DoL office for well over a decade, renewing simply over the internet with the new license arriving by mail.
EDLs have been offered in Washington for several years and the fact that normal licenses would eventually not be good at TSA has been apparent for several years as well. I decided
not to get an EDL in light of those facts very deliberately.
As I've said twice before on this thread, I am not a fan of using passport just for TSA, don't do it myself, and don't advocate for others to choose that option. But having to have a Real ID license to clear TSA without using a passport is not the only option for many people.
