Do I have to take a written test if switching a CDL drivers license from another state to California?

Its true, we dont trust out of state drivers. You will have to take the test.

It is true; the land of fruits & nuts just has to be different from everyone else. The CDL system was intended to make qualifications for commercial drivers universal and took effect in 1992. But, I had the same problem when I moved out of California, the other states made me take both the written test and the road test again. Also, you will need another DOT physical; but since you have to get one every two years and anytime you change companies it isn't a big deal. Most truck companies pay for the physical. If you are remaining employed at the same employer after your move, ask your HR department or safety person about that.

Yes you need to take a written test (and all the the answers above are wrong.... The first one marked "best answer" obviously did not read your question and the fact that you do NOT have a renewal notice yet). I had the same exact situation as you, called the DMV, they said I need to show up at the DMV branch (for photo and vision, never mention test). Waht an ordeal in the DMV and bunch of asses; after waiting for 3 hours, I got to the window, and encountered the most obnoxious rude and ignorant agents, what bunch of ^%^, terrible. Then - suddenly- they send me to a written test... What? Where is this from? Oh, they say, everybody needs it upon renewal (bunch of liars). I think it is because a.I did not have a renewal notice on hand and b.I had 5 months (and need to travel as you) before expiring and they treat it as a "new application". So, with not a chance to study and review the material I had to do the test (surely better to fail than to come back to this hell on earth place). (Yeh, passed). So - get ready. And surely you may have some more surprises.....

My advice, move to CA, leave your license in WA. get a P.O. Box and have a friend forward important letters to you. I would reimburse your friend for any troubles. This is more than likely illegal, so don't get caught. If you do decide to become a full blooded Californian, you will need to take all the tests all over again, including the drive portion, if I recall correctly.

Other than the warmer weather, I can't see any good reason to move to California anyway. Most people who can afford to get away are leaving California. Unless you really enjoy paying one of the highest income taxes in the country, I'd stay far away from the land of fruits and nuts.
