Truck car accidents reportedly take the lives of nearly 450 innocent bystanders each year in the United States. Common causes of truck car accidents include speed, driver fatigue, mechanical failure, failure to yield the right-of-way, disobeying traffic laws and driving under the influence of alcohol. SUV's have a much higher roll-over rate because they have a much higher center of gravity that smaller cars, and a much narrower wheel base. Roll-over truck accidents have a higher rate of fatalities than regular car accidents. Post-collision fires pose a very serious risk of burn-injury to individuals involved in a truck car accident.
