Many drivers are curious about who is at fault in an accident when snow and ice are a contributing factor. The elements of snow and ice do not factor that much into who is at fault in an accident. For example, if you are rear ended because the driver behind you lost control due to black ice, he is at fault in the accident and you may be entitled to compensation for your injury and economic damages. You assume the risk of bad road conditions when you decide to drive in bad weather. Hence, you are responsible for the damage you cause as a result of an accident.
It's always safer to make sure you do not drive when road conditions are hazardous. As they say...better safe than sorry.
