Car accidents on the highway usually result in severe injuries and death due to the speed of the vehicles and highway conditions. Other vehicles are also more likely involved given the proximity of vehicles to one another. People sometimes try and shift fault from themselves. It is imperative you contact an attorney. Do not rely on the police all of the time because they are overworked and with government cutbacks, there are not enough traffic homicide investigators. Attorneys with experience can hire the right accident reconstructionist to determine exactly what happened. Preserve all evidence, take picture, and save the vehicle in serious cases.Remember, insurance companies are not your friends. Who is looking out for you?
