Auto Accident at a T intersection

In these kinds of cases the attorneys who evaluate these kinds of accidents apply what is called the "reasonable person" standard because that is what an arbitrator or jury would be required to do.  The "reasonable person" is basically a fictitious entity that would act reasonably in any given situation.  Based on the facts of your question, one would have to decided if the other driver could have done something that a "reasonable person" would have done in order to help avoid the collision.  The same standard would apply to you.
