This report summarizes the findings and conclusions of a study to establish length limitations for heavy trucks that regulate trailer length (or, in the case of straight trucks, the length of the cargo-carrying portion). The report focuses on the basic principle of limiting trailer or cargo-carrying length in order to remove a major economic incentive that could jeopardize safety. It is recommended that the Department of Transportation should develop model length limit regulations that do not provide an economic incentive to increase cargo space at the expense of tractor length. The Department should recommend to the appropriate State authorities the they establish length regulations that specifically limit the length of trailers (or cargo-carrying portions) rather than merely setting a single limit for the overall length of heavy trucks. While it may be appropriate to have additional limits on overall length, a primary objective should be to reduce the possiblity that non-cargo-carrying length will be decreased at the expense of safety.
