According to the Wyoming Department of Motor Vehicles (see reference 1), all scooters are required to be registered before they can be operated on any highways or public roads. You need a current Wyoming driver's license, proof of insurance and proof of ownership to register your scooter in the state of Wyoming. You must register your scooter at the county treasurer's office in person. Fees vary from county to county but will include the following: state registration fee, county registration fee, license plate fee and sales tax. Once you've received your registration, you must keep it on you at all times while operating your scooter.
According to the DMV, you're not required to have a motorcycle license to register your scooter in Wyoming. If you're under the age of 18 and don't have a driver's license, you're not permitted to operate a scooter on public highways. If you're visiting the state of Wyoming and have a scooter with you that you plan to use during your visit, you must adhere to all of the state's requirements except for having a Wyoming driver's license. You may operate a scooter in Wyoming if it's registered and insured in another state and you have a valid driver's license during your visit. It's recommended that you take motorcycle safety classes offered by the Department of Transportation to improve your roadway skills and educate you on highway safety.
You must obtain valid insurance before you can operate your scooter on public highways. It's illegal in the state of Wyoming to operate a scooter without valid insurance. You must keep proof of insurance with you whenever you're operating your scooter in the state of Wyoming. Insurance rates may vary, depending upon your driving record, but generally the rates are less expensive compared to automobile insurance rates.
