UMTRI survey data on large trucks involved in fatal accidents and on the travel of large trucks provide estimates of fatal accident involvement rates by driver age. The analysis is focused on the implications of lowering the minimum age for drivers of commercial trucks operating interstate from 21 to 19 years. Fatal accident involvement rates for drivers of large trucks were found to increase with decreasing driver age. The younger drivers were over-involved until about age 27. Drivers under the age of 21 were over-involved by a factor of 6 in comparison to the overall rate for all drivers. Several other factors known to have significant influences on the probability of involvement in a fatal accident were examined to determine their association with the over-involvement of younger drivers. These factors were truck type, road type, time of day (day/night), area (rural/urban), trailer body style, and operation (interstate/interstate). The general pattern of over-involvement for younger drivers pervaded virtually every combination of factors examined. The results of this analysis substantiate an elevated risk for younger drivers of large trucks.
