This is mostly a set of questions for tod701. Ive seen the thread at http://www.advrider.com/forums/showthread.php?t=196982 with many concerned questions and differing opinions. User tod701 was most authoritative, having written many of the laws. Even so, Im still not clear. I'm gonna describe my understanding of the tag and pass requirements, and I'd appreciate authoritative corrections. Anecdotal reports of being cited by DNR or Rangers, or not, are helpful but not authoritative. Let me take it step by step. Before getting into it, it's worth remembering that DNR receives funds from the Discover Pass. It is intended to fund state parks. Funds from ORV tabs go directly to ORV facilities. OK, first: In WA State, You need a street (CYC) registration to ride on the road. You need an ORV registration to ride on state-managed off-road areas. Except! Per Tod, vehicles sold from the original manufacturer with street plates are exempt (for now, as of June 2013) from Washington State ORV permit requirements. See RCW46.09.420(6) http://apps.leg.wa.gov/rcw/default.aspx?cite=46.09.420 So, if you have a dirt bike, used on state land, including but not limited to ORV parks like Tahuya, you need an ORV tab. If you have a plated bike, and it was originally sold as a dual-purpose bike (examples: Yam WR250R, or KTM 530EXC), then you dont need an ORV tab to ride both road and ORV areas. [But you may need a Disco pass. See below.] If you have a converted bike, such as a WR250F or CRF450R with a plate, then you need both plate and ORV tab to ride both road and ORV areas. Motorcycles converted for dual use pursuant to RCW46.61.705 must be dual registered. http://apps.leg.wa.gov/rcw/default.aspx?cite=46.61.705 Let me ask about some examples: 1. Suppose I have an ORV-only registered bike, like a KTM 300SX with ORV tabs. At Tahuya on the ORV trails, I need the ORV tabs, and I don't need a Discover Pass or a CYC registration. But if I am riding in a non ORV area on state land, like the paved roads leading through Tahuya State Park, then I need a plate and CYC reg, because its a public road. Also I need a Discover Pass. The ORV tabs mean nothing in a non-ORV area. Question 1. Right? 2. Suppose I have a dirt bike, like a Yam WR450F, that Ive modified for dual use. It has a horn, flashers, and a WA plate and ORV tabs. At Tahuya on the ORV trails, I need the ORV tabs, and I don't need a Discover Pass. If I am riding in a non-ORV area on state land, like the paved roads leading through Tahuya State Park, then I need a CYC registration and plate. This example is for a dual-registered bike, so Im good here. I also need a Discover Pass, because it is state land + state road. The ORV tabs mean nothing here. Question 2. Right? 3. Suppose I have street-registered dual-sport bike, like a Yam WR250R. I do not have ORV tabs. At Tahuya on the ORV trails, I don't need ORV tabs, because I have a CYC registration on the dual-sport (non-converted) bike. I also dont need a Discover Pass to use the bike on these trails. But if I am riding the paved roads leading through Tahuya State Park, then I need a CYC registration + plate (which I have in this example) and I also need a Discover Pass. Question 3. Right? Q4. What about USFS roads? Do I need CYC+Plate? Do I need an ORV? Discover pass? In my mind, the Discover Pass is simple: If you must be street legal to drive/ride where you are at and that is a location where a D-pass is required, then the D-pass is still required regardless of whether or not you have an ORV permit. The Discover Pass implies a use fee for State parks, and ORV tabs dont suffice to meet the obligation. One exception are roads within DNR managed public land, which belong to the county. Discover Passes are not required on county roads. Many ORV trailheads are accessed thru DNR land via county roads. In that case, then no D-pass is required. I should think of the Discover Pass is just an overlay usage fee, for state parks. It applies to vehicles which must be licensed for the road. If I transport bikes to an ORV park with a truck, I will certainly need a Discover pass for the truck, regardless as to the registration status of the bikes. A dual-registered vehicle needs a D-pass anywhere within a D-pass area where the vehicle must also be street legal. Examples: State Park roads. WDFW roads **if you are required to be street legal to use them. DNR roads **if you are required to be street legal to use them. Question 5: Is all of this correct? I'd appreciate clear answers. I know this has probably been discussed many times, but I'm still not clear. Thanks.
