The study examined the need for increased protection of large trucks and trailers against passenger care underride during rear end collisions. An analysis was performed of: the use characteristics of large trucks and trailers over 10,000 lbs. GVW; the configuration of current underride guard devices; and the design changes, cost and user impact that would result if improved safety requirements were imposed. Results indicated that the greatest potential underride hazard exists for vans and flat bed vehicles, particularly semi-trailers with sliding tandem axles in the forward position. Of the 545,000 newly registered large straight trucksand trailers in 1978, 260,000 are potential rear underride hazards. Four underride guard designs weighs less than 300 lbs., requires minimal vehicle modification, imposes no restrictions on rear axle slider position, and may be constructed of low cost standard structural steel. Unit cost is estimated at less than $200 over new vehicle purchase price. Ground clearance and weight of the proposed new guard would have minimal impact on user revenues, fuel cost, and loading and docking operations.
