The leaves are falling now and even when the weather is fairly warm, if it rains, the leaves combined with rain and oily discharge from vehicles can make the roads quite slick. It doesn't have to be snowing or sleeting for the streets to be slippery. Be careful. Remember that if you hit a patch of slippery leaves and rear-end the car in front of you it is still your fault. Leave plenty of distance between your car and the ones in front of you whether or not it is rainy.
