My mom was hit by a car. She was walking across the street and a car just sped in 20miles and hit her left arm twice.

I don't see a question anywhere in your entry, but I'm assuming that you are inquiring about whether your mother has a good legal claim or not.  There are several elements that must be present in order to make a good case: 1. Negligence - She is going to have to show that the driver was at fault, not her.  Because you acknowledge that she was crossing illegally, that is going to be strike against her, but maybe not fatal to her case.  If the driver was also driving too fast or recklessly, she may be able to make a claim.  In Virginia we have a rule called "contributory negligence" which means that if your mother was even a little bit negligent in causing her own injury, then she would get nothing.  But in reality, juries often ignore this rule and may give her something.   2. Causation - She has to show that the accident is what caused her injuries.  This should not be hard to do in this case.  But sometimes there are pre-existing injuries that get exacerbated by the accident and that can be hard to prove.  3. Injury - You did not describe the extent of her injury.  How badly was she hurt?  Did she require medical treatment?  Was she taken away in an ambulance?  What is her prognosis?  If she was hit, but not injured, then it is not much of a case. 4. Damages - Her injury must be severe enough to be worth something.  While even the smallest injury causes some pain and suffering, the amount of pain for something like a bruised knee or a paper cut would be so small as to not be worth pursuing.  Typically in order for a lawyer to consider the case worthwhile, she would have to have injury severe enough to warrant further medical treatment.  The amount of money a person may likely recover is usually related to amount of the medical bills, plus pain and suffering.  The old rule of thumb is three times your medical bills, but that is just a ballpark.   This answer is given in accordance with the laws of Virginia and may not be applicable in any other state.  It should not be construed as legal advice, as that would require a more thorough analysis of all of the facts involved in a specific case.  If you need further information or assistance, please feel free to contact my office for a consultation.
