Assuming you were "under the influence" the answer hinges on whether this is a "vehicle" under the statute and whether it was being operated on a "public roadway." Although the caselaw leaves some gray area in the law, a segway probably meets the definition of a "vehicle" under the DUI law. I have successfully argued that a motorized scooter was not and was not so successful trying to apply this argument to a small electric motorcycle. Probably depends on the court, but most judges will probably rule that it is covered in the statute. "Public roadway" is very broadly defined would include almost any path or roadway potentially accessible to the public. Thus, the answer is probably yes and you probably wouldn't be the first to be arrested for riding a segway under the influence.

Yes. Under Washington law, it is unlawful to drive a vehicle while intoxicated. The definition of "vehicle" under the Revised Code of Washington includes " ...every device capable of being moved upon a public highway and in, upon, or by which any persons or property is or may be transported or drawn upon a public highway, including bicycles." A Segway would fit the definition as a device, upon which a person may be transported.
Because a Segway is a Electric Personal Assistive Mobility Device under Washington State law it is not a motor vehicle. The DUi statute only applies to teh operation of motor vehicles. So no a person could not be charged with DUI for operating this device while intoxicated. However, operating that device or any other while intocxicated could lead to charges of reckless endangerment, negligent assualt or worse. Be careful out there so that no one gets hurt!!!
As of July 1, 2011 the Washington law changes. The Electric Personal Assistive Mobility Device is expressly defined as not a vehcile nor a motor vehcle. Please see Senate Bill 5061 referenced below.
