Why we wrote these
Most of what riders find online about Washington law is either a law firm advertisement or a forum argument. Both tend to be confidently wrong, and the wrong ones get repeated. The insurance question is the clearest example: plenty of pages still say motorcycles are exempt in Washington, because they once effectively were. They are not now.
WMST trains riders and administers the official DOL tests, so we read these statutes for a living. Each page in this section quotes the actual text, links to it on the legislature site, and then explains what it means when you are the one at the intersection.
Licensing and permits
Washington separates the permit from the endorsement. The permit lets you practice under restrictions. The endorsement is what actually goes on your license and lets you ride freely.
The DOL charges $35 for your first 180-day permit and $15 to renew it, and you may hold at most two of them in any five-year period. While you hold one you may not carry a passenger and may not ride during the hours of darkness.
The endorsement comes after you pass a knowledge test and a skills test. Completing an approved training course can waive that DOL testing, which is the route most riders take. Our testing guide explains how the waiver works, and the permit guide covers whether you need one first.
On the road
Three rules govern how you use the lane. You are entitled to the full lane, and other drivers may not crowd you out of it. You may ride two abreast in a single lane but no more. You may not split or filter between lanes, even in stopped traffic.
There is one narrow exception to the red light rule: if a signal will not detect your bike, RCW 46.61.184 lets you proceed after a complete stop and one full signal cycle.
Equipment
Your motorcycle needs mirrors on the left and right giving a view at least 200 feet to the rear. You need eye protection, glasses, goggles, or a face shield, unless the bike has a windshield. And you need a helmet that carries the manufacturer certification under 49 C.F.R. 571.218, which is what a DOT sticker signifies.
What to actually buy, and what the range requires you to show up in, is covered in what to wear to a motorcycle class.
This is a guide, not legal advice
We quote the statute and link to it so you can read the primary source. Statutes get amended, and how a rule applies to a specific stop is a question for a lawyer, not a training school. If something here matters to your situation, read the RCW directly and get advice from someone qualified to give it.
