I have been shunted into standard vehicle lanes on the ferry from Fauntleroy to Southworth because “ it is as wide as a car”
If you get into the fine print on the WSDOT web site, in the WA Ferry fare details, I've found where any 3 wheeled vehicle (including 2 wheeled motorcycles with a side car) should pay the smallest car price but we load with the motorcycles. It's not the $ I mind, I just don't want to wait/load with the cars. PM me if you've been made to load with the cars, as we should say on top of this to preserve our priority in the queue.
