STAY OUT FROM IN FRONT OF A RIG!!!!
Three times this week I've been cut off and had to ride the brakes to avoid impact. It's a scary experience for me even though I'm likely to survive the accident - the driver of the car is not. Consider the following.
1) A fully loaded 80,000 semi-truck going 30 MPH strikes with 2.4 million pounds of force. For your typical 3000 pound car to have the same impact it would have to be travelling 1,600 MPH, or well over twice the speed of sound!
2) The energy released in this collision is roughly equivalent to 10 sticks of dynamite. (I'm sure pbartender or another scientist who frequents this board can give a more accurate units related calculation).
3) A truck going 60 MPH needs 333 feet to stop - compared to 233 feet for a car. So even if you and the truck driver hit the brake at the same time, if you're in front of the truck you could get hit.
4) When trucks hit cars hard they ride up and over them, most of the time, crushing the occupants.
Please, please, please keep this in mind, because neither I nor any other truck driver wants to have a fatal accident with a car on their conscious. Get at least 100 feet (truck length and a half) in front of a truck before returning to the lane in front of it. In heavy traffic do not be eager to get into the space ahead of the vehicle - that space cushion is needed to bring the vehicle to a stop. In general stay far, far away from these vehicles if you can.
Large trucks can KILL you.
EDIT: And this goes quadruple if you're on a motorcycle. One of the fools who cut me off this week was on a bike. Note that NO ONE in the last 5 years has survived hitting a truck with a motorcycle - such an accident is 99.9% likely to be fatal for the cyclist.
