Wow. Amazing how fast a truck tips over. Not something you see every day. Usually a good idea to obey the speed limits I guess, especially in the mountains. Here is what it looks like and how fast it happens. Technology has come a long way. Watch what this CR England truck with an in-motion camera captured. This accident was filmed by a CR England driver with a dash cam going down Donner Pass. Note the flashing 55mph sign prior to the accident.
