Grants an insurance company the right to require a mandatory inspection by an insurance company representative or agent of any motor vehicle prior to agreeing to provide insurance coverage. Permits a company to waive such right under specified circumstances. Allows an insurer to require a pre-insurance inspection of an otherwise exempt motor vehicle, but prohibits basing such decision on the age, race, sex, religion, or marital status of the applicant or insured or the fact that the vehicle has been insured through a residual or non-voluntary insurance market.
