After getting my DL650 hacked by DMC I decided to get my endorsement. I found out that there are two ways, to take the 3 wheel course or take the written and riding test without the taking the class. The state no longer administers the tests. Getting the required information on the material was a bit difficult, since the Department of Licensing web site is not the best. For the written test, the guys at Pacific Northwest Motorcycle Safety, the ones who do the training and testing in our are, Seattle, King and Kitsap Counties were very helpful. They recommended I download and study the three wheeled riding book from the DOL web site. I did so and got a 96 on the written test. Knowing what would be on the riding test was more of a challenge since there is surprisingly nothing on the DOL site that outlines on we will be tested. In my opinion the DOL should state exactly what the criteria should. I finally sent a note to the school and got an informative response. My concern was that I'd have to fly the car and several riding friends told me I would, since it is done in the course. Drone gave me some good advice to include suggesting I do this post. The riders test is four part. 1. This is a series of 90 degree turns around cones, a left turn followed by a right and then a 45 degree turn. This is a timed test. The rider can fly the car if desired in the turns but I chose not to, keeping about 40 pounds of ballast in the trunk of my car. 2. The second part follows right out of completion of the timed 90 deg turns and is not timed. It is a sweeping left turn coming out of the cones. Coming to a stop in a green box. Stopping in the box is to test if you know where your front wheel is. It is immediately followed by a reverse of the same course, a sweeping right turn. 3. Swerve. The rider starts from a point about 30-40 yards from two cones with a series of cone block just beyond the swerve point. This is timed. The rider must approach the two cones at about 18-20 mph (as I recall) and when reaching the line between the conses, immediately swerve right and then left, maintaining control of the rig. If you anticipate the swerve, points are taken off. I lost a couple of points on this because I might have anticipated the arrival/start of swerve point. 4. Braking. From a bit longer distance the rider approaches two cones, like #3, about 15 feet apart. When you reach the line between the cone you are to brake hard and straight, coming to a complete stop. I lost seven points on this one, not realizing that there was a measured distance. I came to a complete stop about 14 feet beyond the line and apparently I should have been able to do it in 11. I had no control over this at all since I hit the binders hard, front and rear/sidecar brakes. That's just the way my rig brakes. It's just like autos with some can do shorter stopping distances than others. DL650 brakes to me are marginal at best. I didn't realize there was a mandated stopping distance and they don't tell the rider. They are not allowed to apparently which is why I think DOL should have to include something on their web site such as course, required skill demonstrating and testing criteria etc. One last, the guys at PNW Safety are really a great bunch and we chatted quite a bit after the test. I barely passed but could have done better had I known some of the criteria such as the time required for the first event. I went through at what I thought was a good clip, and could have gone through faster had I wanted to. Oh well. At least I have my endorsement. Cost for the written test was $35 and the riding $50. The 90 three wheel riding permit was $15 as I recall. My bill for the endorsement at the DOL was $37 which included the fee for early license renewal of my license.
