Proportionate responsibility laws determine the effect of your own potential partial fault in causing an accident. Your recovery will be reduced by your percentage of responsibility for causing an accident. In Texas, a person may not recover anything if he or she is more than 50% at fault for causing an accident. New Mexico has pure comparative fault rules, which means that the trucking company may still be required to pay for their fair share of your injuries even if you are more than 50% at fault for causing the accident.
