Nev. Rev. Stat. § 485.3092
When an insurance carrier has issued a motor vehicle liability policy, the insurance so issued must not be cancelled or terminated until at least 10 days after a notice of cancellation or termination of the insurance has been mailed first class or delivered to the insured and, if the insurance carrier has certified the policy under NRS 485.308 or 485.309, a notice has also been filed in the office of the Department. A policy subsequently procured and certified, on the effective date of its certification, terminates the insurance previously certified with respect to any motor vehicle designated or the person named as the insured operator in both certificates. If the effective date of the termination is within 3 years after the date of reinstatement of a license, registration or privilege, the Department shall suspend the license and registration or privilege.
