Wyo. Stat. Ann. § 31-2-225
in effect(a) Applications for registration of vehicles shall be filed in the office of the county treasurer in person, by regular mail, or if available, electronically, in the county in which the owner of the vehicle resides or in any county in any other case and contain:
(i) Information required by W.S. 31-2-103(a)(i), (ii), (vii) and (ix);
(ii) Unladen weight if required to compute fees and taxes;
(iii) The purpose for which the vehicle is used and such other information as required by the department or the county treasurer;
(iv) Color of the vehicle at the time of registration;
(v) Information regarding whether the owner desires to donate one dollar ($1.00) or more to promote awareness and education efforts for procurement of organ and tissue donations for anatomical gifts.
(vi) The option for the owner to donate an additional amount to provide for wildlife conservation efforts related to the transportation system;
(vii) The option for the owner to donate an additional amount to support search and rescue operations under W.S. 31-2-234.
(b) The department, county treasurer or any peace officer may cause a truck or trailer to be reweighed at any time and a new weight certificate issued. A copy of the certificate of registration shall be carried at all times in the motor vehicle for which it is valid and shall be displayed upon demand of any peace officer.
(c) County treasurers shall not register nor renew the registration of a vehicle unless a certificate of title has been issued to the owner or the owner presents satisfactory evidence that a certificate of title for the vehicle has been previously issued to the owner by any county clerk except:
(i) A county treasurer may register a vehicle without the Wyoming title of an applicant who is an owner, lessee or operator if the vehicle is required to be registered in Wyoming, and the owner, lessee or operator, if applicable, presents proof from any jurisdiction of a current registration and any other requested documentation from any other source necessary to satisfy the treasurer that the applicant is the owner, lessee or otherwise has lawful right to the vehicle as an owner, lessee or operator.
(d) Applications for a specific license plate number shall be made to the county treasurer by the last day of the annual registration month. The county treasurer shall determine the number of license plates to be reserved for each license plate type, but in no case shall the number reserved for any registration year for any one (1) type exceed nine thousand nine hundred ninety-nine (9,999).
(e) No motor vehicle shall be registered unless the applicant verifies the motor vehicle is covered by a motor vehicle liability policy in full force and effect in amounts provided by W.S. 31-9-405(b) or a bond on file with the department in amounts provided by W.S. 31-9-102(a)(xi). The department shall adopt rules and regulations to implement this subsection. This subsection does not apply to self-insurers under W.S. 31-9-414. Issuance or renewal of registration by a county treasurer does not constitute verification or certification on the part of the county treasurer that the registered vehicle is in fact covered by required insurance or bond and neither the county treasurer nor any employee of the county treasurer's office is liable for damages caused by any person operating a registered vehicle in violation of W.S. 31-4-103(a). Proof of insurance shall be carried at all times in the insured vehicle and shall be open for inspection at all times when requested by any peace officer. Any applicant making a false certification required by this subsection or failing to provide proof of insurance on the registered vehicle as required, is guilty of a misdemeanor punishable pursuant to W.S. 31-4-103(a) upon conviction.
