1) NEVER GO INTO NEUTRAL
2) go lower gear, power out if you ever start losing control, that valuble traction you might hook on to is your friend
3) get snow tires, not all season shit, i have two sets, a summer and winter. My vw golf with winter tires is a fucking tank on the streets, in 2-3 inches of snow, no problem, hell ive tackled ice before
4) obviously dont drive stupidly fast
5) light breaking and try to downshift obviously
6) obviously dont break hard while turning at faster than usual speeds
and my final tip, go into a parking lot full of snow and practice losing control and do e-brake drifts, get familiar with what it feels like to lose control, and what full force ABS on a car with no diff feels like, scares the shit out of me every time it kicks in!! Its like someone is humping my tranny, honestly.
