Having driven in the winters of Ohio, Kentucky, Western PA & northern WV, I can tell you that RWD vehicles, when equipped with a sensible, knowledgeable driver
AND the proper tires, can do just fine in the snow. And as Deadman said, throw some weight in the back, over the axles, if you go to areas that are especially slippery. I typically used about 6-8x 80lb bags of concrete mix, but bags of top soil or landscaping rocks will do also. A friend of mine used a bunch of cinder blocks too
Just remember:
A) Slow the f*ck down & take your time
B) Driving on snow/ice/slush-covered roads is NOTHING like driving in the rain or any other weather conditions
C) Whenever possible, use the same tire tracks that are already there
D) Driving in an active snow STORM is dangerous as hell, but can be done
E) Slow the f*ck down & take your time
F) Keep plenty of room between you & other cars, at least 2 car lengths all around, in front & back
G) Slow the f*ck down & take your time
I) Don't make sudden, quick movements
J) Stay off the brakes, especially in turns & going downhill
K) Slow the f*ck down & take your time
I know that's alot to grasp, but it's gotten me through 45+ years of driving on snow/ice/slush-covered roads WITHOUT A SINGLE accident, spin out, or need of a tow truck
