Yes, you may -- and this applies not just to out-of-state plates and placards, but even to foreign ones, provided your credentials are valid, current, and that the person to whom they apply is traveling in the vehicle. Handicapped credentials do not exempt the vehicle from any applicable parking fees or meter payments and the minimum fine for illegally parking in a handicap space is $250, so don't do it!
For further information, allow us to refer you to the relevant section on the Nevada DMV's website. Plus, while we confess the specific company details (phone numbers, fees, whether they're still even in business!) have not been updated in some time (it's on our list...), we also recommend you check out the page with Transportation Tips for travelers with disabilities, where all the basic overview facts and tips still hold true. Plus, check the recent archive (2/24/14, to be precise) for an in-depth answer supplied by a long-time LVA member who is confined to a wheelchair and shares all kinds of useful tips and personal experience about renting scooters and wheelchairs and getting around town when you are mobility-challenged.
We hope this helps, and if any readers out there have additional inside information and personal experiences to share, please drop us a line.
