Let me add to what Jato said.
Not only drive slow, but drive deliberately. Allow more space, pay very close attention to what the other loose nuts behind the wheel are doing and so forth.
So you must leave much more space between you and the cars around you if you can.
Momentum, it may be your friend, but can also be your enemy. It is harder to get started, so if you can keep moving, you are less likely to get stuck.
However, it is also harder to get stopped if you need to, so you have a greater chance to run into things, like other cars, curbs, etc.
Snow is not nearly as bad as ice. You can usually see snow, but you often cannot see ice.
Bridges and overpasses often freeze over before the rest of the road surface freezes.
You should be able to see out of all of your windows before you drive off. You are not driving an Abrams tank, so don't just clear off a port hole in the front before you drive away in the morning.
Use your lights, it's not just about you being able to see, but others being able to see you. Especially if you have a light colored car in snow use them. It is not easy to see a white or silver car in daylight when the background is snow.
(This is a pet peeve of mine, 99% of people think their head lights are there just so they can see, they are also there so others can see you. So use them at dusk and at dawn, even if you can see fine, if you can't see the cars behind you from the glare of the sun, then you need your headlights on.)
FWIW,
