Can someone tell me, simply, what to do if your car goes into a skid/spin because of bad weather?

in you most likely have RWD... the best option is to let off the go-pedal, don't use the brake, and steer where you want to do, don't OVER compensate that will just make you spin in the other direction. if you have a FWD car you should only be skidding/spinning if YOU want to(I've had fun in FWD cars on snow) just remain calm, panicking will only make it worse. and be smart when driving in the winter...
