You know that gross, gray, sludgy mix of snow and dirt that forms on the side of the roads when the ice starts to melt? That slush can create serious problems when you're driving, and it's very different from driving in ice and snow.
While driving on snow and ice usually means proceeding carefully so your tires don't slip, slush is grabby and can suddenly slow your car down. Way down. Slush can also grab at your tires and make lane changing a difficult operation. Remember to drive extra slowly in and around slush, and don't panic if you lose control of the car; stay calm and regain control by lifting off the accelerator or gently applying your brakes.
Another problem with slush is that it can accumulate on your windshield, which blocks your vision. Sometimes you'll have to pull over to wash it off because your windshield wipers simply won't cut it. Slush along with dirt, grease and chemicals from the roads can also accumulate on the bottom of your car and cause corrosion. So make sure you're keeping your car properly clean during these conditions.
