有一次下班在一个Stop Sign右转。一看没有车就开始转,再一看一个黑乎乎的车就在我的车前经过。我Core!等我追上前面的,我狠狠地给了车主几个beeps.
Rear-End Collisions
If someone hits you from behind, it is virtually never your fault, regardless of why you stopped. A basic rule of the road requires a vehicle to be able to stop safely if traffic is stopped ahead of it. If it cannot stop safely, the driver is not driving as safely as the person in front.
The other sure-fire part of the rear-end accident claim is that the damage proves how it happened: If one car's front end is damaged and the other's rear end is, there can't be much argument about who struck whom. Of course, the driver of the car that hit you may have a claim against someone who caused you to stop suddenly, or against a third car that pushed his car into yours, but that doesn't change his or her responsibility for injuries to you and damage to your car.
Keep in mind, however, that even if you have been rear-ended, in a few circumstances your own carelessness may reduce your compensation under the rule of "comparative negligence." A common example is when one or both of your brake or tail lights were out, especially if the accident happened at night. Another example is if you had mechanical problems but failed to do all you could to move the vehicle off the road.

Left-Turn Accidents
A car making a left turn is almost always liable for a collision with a car coming straight in the other direction. Exceptions to this near-automatic rule are rare and difficult to prove, but they can occur if:
The car going straight was going well over the speed limit.
The car going straight went through a red light.
The left-turning car began its turn when it was safe, but something unexpected made it slow down or stop. This is an extremely difficult exception to use because a basic rule of the road says a car making a left turn must wait until it can safely complete the turn before moving in front of oncoming traffic.
As with a rear-end collision, the location of the damage on the cars sometimes makes it difficult for the driver to argue that the accident happened in some way other than during a left turn.
