Nevada law provides that UM coverage must be offered and must include UIM protection. N.R.S. 687B.145. UIM protection is excess type coverage rather than reduction type coverage. Consumer can waive UM coverage but this waiver must be done in writing. The amount offered must equal the amount of BI liability coverage. Mid-Century Ins. Co. v. Daniel, 101 Nev. 433; 705 P.2d 156 (1985).
The UIM carrier has no right of subrogation against a driver who has purchased at least the minimum liability limits of coverage.
