We received three to four inches of snow in Reno on the day of December 3, 2013. I took the bus that day from a stop on Keystone Ave in front of Raley's. I noticed that the SUVs were going the most consistent speed out of all the rest of vehicles, for SUVs are unique in the respect that they weigh almost as much as a pickup truck and they have a slightly longer wheelbase than a regular car. On December 4, I was taking the bus to work because I knew the roads would be too dangerous for me to ride my bicycle on. As I was waiting at the bus stop on 7th Street, I noticed that a lot of people were using caution and slowing down. That's a good start, for if you go too fast; the tires on your vehicle will not grip the road surface very well. Make sure to place some ballast in your vehicle, for it helps your vehicle gain more traction. Examples are sandbags, firewood, tires or other moderately heavy objects.
I would buy a pair of chains or cables to store inside your vehicle year-round, no matter what. I have seen snow fall in Reno on Memorial Day of 2010. Ask some of the locals that have lived in Nevada more than ten to twenty years about the times they saw snow fall (outside of the winter season). It is a bonus to keep your vehicles indoors. If you don't, I would make sure to buy a container of antifreeze for not only your vehicles, but for any small equipment like a snowblower; bobcat, etc. There is this chemical called Rain-X that can help clear the frost off your windshield easily when you don't have the time to use a scraper, I bought a container for my mom to use on her car once.
Also, make sure to tune up your vehicles and pay good attention to maintaining your transmission service schedule, brakes and all the important things. Since winter driving involves a lot of stopping and accelerating, and having to plan ahead for the times that your vehicle may go out of control; make sure you take good care of your vehicle so that it has a greater chance of surviving through another winter. If the dealership or a mechanic gives you special advice for winter driving or winter maintenance on your vehicle, do your research in books from the library or on the Internet and make sure it makes sense to you.
I would read out this article from the Reno Gazette-Journal, it is pretty thorough.
In Reno we received some more snow last night, and there may be more on the way. I heard a lot of people saying back in the fall that this winter will be longer and wetter, so these doses of snow are only the "wetter" portion of winter. It has hardly fallen below zero in most winters that I have lived in Northern Nevada, but it looks like this winter may be one of them.
