I've always been told that when you come to a red light or stop sign, to stop far enough behind the car in front of you so that you can see the bottom of their back tires. While a good general rule, I was wondering what would happen if, while you were following this rule, a much larger/speeding vehicle rear-ends you, causing you to hit the car ahead. Would the size/power difference be taken into account as to who's at fault for hitting who? I'm not looking for specific ratios, only if it matters. A bonus would be how much weather is taken into consideration.
Currently in CO, but do find myself getting out quite a bit.
