(B) an analysis of the percentage of trucks 
operating in excess of the Federal size and 
weight limits; and 
(C) an analysis that examines the ability of 
each State to recover the cost for the impacts, or 
the benefits incurred; 
(3) evaluate the impacts and frequency of viola-
tions in excess of the Federal size and weight law and 
regulations to determine the cost of the enforcement of 
the law and regulations, and the effectiveness of the 
enforcement methods; 
(4) examine the relationship between truck per-
formance and crash involvement and its correlation to 
Federal size and weight limits, including the impacts 
on crashes; 
(5) assess the impacts that truck size and weight 
limits in excess of the Federal law and regulations 
have in the risk of bridge failure contributing to the 
structural deficiencies of bridges or in the useful life 
of a bridge, including the impacts resulting from the 
number of bridge loadings; 
(6) analyze the impacts on safety and infrastruc-
ture in each State that allows a truck to operate in 
excess of Federal size and weight limitations in truck- 
only lanes;

(7) compare and contrast the safety and infra-
structure impacts of the Federal limits regarding 
truck size and weight limits in relation to— 
(A) six-axle and other alternative configura-
tions of tractor-trailers; and 
(B) safety records of foreign nations with 
truck size and weight limits and tractor-trailer 
configurations that differ from the Federal law 
and regulations; and 
(8) estimate— 
(A) the extent to which freight would be di-
verted from other surface transportation modes 
to principal arterial routes and National High-
way System intermodal connectors if each cov-
ered truck configuration is allowed to operate 
and the effect that any such diversion would 
have on other modes of transportation; 
(B) the effect that any such diversion would 
have on public safety, infrastructure, cost respon-
sibilities, fuel efficiency, and the environment; 
(C) the effect on the transportation network 
of the United States that allowing each covered 
truck configuration to operate would have; and 
(D) whether allowing each covered truck 
configuration to operate would result in an in-

scribes— 
(A) the size and weight limitations applica-
ble to each segment of the National Highway 
System in that State as listed under paragraph 
(1); 
(B) each combination that exceeds the Inter-

Transportation, other Federal agency, or a State 
agency has determined on or before the date of 
enactment of this Act, could be or could have 
been lawfully operated in the State; and 
(C) each combination that exceeds the Inter-
