Wyo. Stat. § 31-9-404 (2026)

(a) The nonresident owner of a motor vehicle not
registered in this state may give proof of financial
responsibility by filing with the division a written certificate
of an insurance carrier authorized to transact business in the
state in which the motor vehicle described in the certificate is
registered, or if the nonresident does not own a motor vehicle,
then in the state in which the insured resides, if the
certificate otherwise conforms to the provisions of this act.
The division shall accept the certificate upon condition that
the insurance carrier complies with the following provisions
with respect to the policies certified:

          (i) The insurance carrier shall execute a power of
attorney authorizing the division to accept service on its
behalf of notice or process in any action arising out of a motor
vehicle accident in this state;

          (ii) The insurance carrier shall agree in writing
that the policies shall be deemed to conform with the laws of
this state relating to the terms of motor vehicle liability
policies issued herein.

     (b) If any insurance carrier not authorized to transact
business in this state, which has qualified to furnish proof of
financial responsibility, defaults in any undertaking or
agreement, the division shall not accept as proof any
certificate of the carrier so long as the default continues.
