Is a 402t still a valid permit once you leave the state? It doesnt seem like it would be, which would be at odds with what Oregon is showing there.
I don’t see any way to request a 402t online. My experience with CA temp tags was they always had to be done in person, but it has been a few years since i had to get one.
I think it would likely be honored, or the WA 3 day permit would.
Almost everything is now online with DMV offices turning people away:
“In an effort to reduce office visits, the Department of Motor Vehicles has now digitized more than 90% of services.”
From my experience on two vehicles this year, it isn’t working well. 
You escaped CA several years back and things have changed in many ways since you have left.
They definitely have a lot more things you can do online now than you could, but in my quick sesrch through the site, this didnt look like one of them.
One of the first things i noticed moving to FL was on my first trip to the dmv, the people were actually helpful, things were quick and efficient, and I didn’t leave the building wanting to torch the place.
You have to open a “case” with the Virtual Field Office, call it whatever you want and you can “virtually” (see what I did there?) do almost anything online.

I have not been in a DMV office in a few years.
Yeah… the discount is offsetting the transport cost by a lot (18K off on a 100K car)… so my thought is to get it shipped… though it would be additional 1500 dollars for transport in a covered container
Covered is rarely necessary, but $1500 for covered might be worth it as the open probably isn’t much less.
Or is that $1500 PLUS the open cost?
$1500 in total for moving cost in covered container
Good discussion but the missing imp qns which is…
What if OP pay the CA Sales tax, and drive the car home with 1-way permit across 3 states? does he has to pay Sales tax again in WA during registration? or WA DMV will see car sales tax is already paid and only thing Obviously he has to pay plate fees and tag fees…which is approx 250 for Non-RTA and 450 for RTA zip code for SUV with GVWR of 5000.
Edit
quick search
Vehicles brought into Washington from out-of-state | Washington Department of Revenue.
Use tax is paid when the vehicle is licensed and registered in Washington. The use tax rate is determined by the vehicle owner’s place of residence.
When the owner can show they paid sales or use tax in another state prior to bringing the vehicle into Washington, they may apply the amount of sales or use tax paid against the Washington use tax. The owner may not take a credit for other amounts paid such as licensing fees, lessor taxes, or value added taxes like Canada’s goods and services tax (GST).
I would think that California could also refund his paid CA sales tax once he shows proof that the car is registered in Washington and sales tax was paid there.
When I researched this, at least two different CA BMW dealers described an out-of-state registration like this:
I didn’t actually end up getting a CA car for use in another state, so I can’t comment on personal experience with the process.
I just called WA DMV, they mentioned that the tax that i pay in California will be deducted when registering the vehicle in WA. Now i just need to figure out that 1 day rule in california, because i don’t think i would be able to exit california in 1 day
The 402t is very explicit that you have to leave day of in the most direct path possible.
What if i am not able to leave it on the same day ? how is it enforced ? i understand if the cop catch me they can but otherwise how will they do it ?
Also, i am wondering if this is possible. I purchase 2 402t, 1 use it for transfering it from the dealership to somewhere north in California for layover. And the next one is used for the crossing outside california into oregon. ?
I have purchased three cars in CA (as an Oregon resident) and am about to lease my 4th. First one was a new car that I paid cash for. They gave me no one day trip permit. They licensed the car in Oregon for me (since it was new) Since it was a purchase, I paid CA tax on it. Second one was a used car cash purchase (and I paid CA tax). They gave me a one day trip permit and I handled my own Oregon DMV paperwork. Third one was a new car cash purchase. I took delivery in AZ and paid no CA tax. The dealer licensed the car in OR for me.
The new one coming next month is going to be leased. I called PFS and was told the tax will be collected on where the car is registered. Since it will be registered in Oregon, we won’t pay any tax on the lease (CA pays sales tax just on the monthly lease payment) and the dealer will license the car in Oregon for me.
