Who can get one
To apply for a 2-wheel instruction permit you need to be at least 16 and hold a valid Washington driver license. If you are under 18, a parent or guardian signs a consent form. You pass the motorcycle knowledge test to get the permit, unless you are getting it as part of an approved course.
What the permit lets you do
The permit is for practice, not full riding. Washington keeps the rules simple: no carrying passengers, and no riding during the hours of darkness, so daylight only. It is valid for 180 days. Think of it as a structured way to build real-world saddle time before you test.
Do you even need one?
Here is the part many riders miss: if you take an approved course that includes the testing, you do not have to go the permit-and-DOL-test route at all. WMST teaches you to ride on a closed range and tests you there, then you take your certificate to the DOL. A permit can still be useful for practicing between class and getting comfortable, but the course is the main path. More in how the course waiver works.
