The vehicle fleet is changing dramatically. Traditional passenger cars are rapidly being replaced by Sports Utility Vehicles (SUVs) and Light Commercial Vehicles (LCV) in Australia. These vehicles are larger and heavier and likely to impact more severely with a traditional passenger car. An analysis of current crash and injury patterns between traditional passenger cars with SUVs and Light Commercial Vehicles in Australia, is currently in progress that will show any likely safety benefits or disbenefits from these trends and will be reported in the paper if accepted.
