The relative safety of single and double tractor-trailer combinations is examined in the light of recent findings on the performance characteristics of the two classes of vehicle. In particular, the accident data are searched for evidence of a safety deficit for the doubles resulting from the phenomenon of rearward amplification. Although there is no conclusive evidence of an overall difference in fatal and injury accident involvement rates between singles and doubles, this is tempered by the finding of a generally safer operating environment for the doubles. There are strong indications that the doubles have a rollover problem in property-damage accidents. The overall conclusion is that the handling characteristics of large trucks are reflected in their accident experience.
