hen you try to run a red light, you take the risk that another car will turn or pull out in front of you, right into your path.
It is equally likely that a pedestrian (perhaps a child) might step out into the crosswalk, trying to cross the street. If either of these things happen, there is likely to be a serious accident and no one will be at fault except you.
Keep in mind that it is exceptionally difficult for another driver to tell how fast you are going or whether your are about to accelerate or stop when they are approaching you head on.
