Truck Size and Weight Reform Some Interstate weight limits in many states frozen in time for more than 50 years. No major weight increase in 35 years 73,280 lbs to 80,000 lbs in 1974. Weight increased 9% in 50 years. 1991 LCV freeze Requests for Exemptions (Logging etc)

Light Rocky Mountain Double 7+ Axles, Maximum GVW – 117,000 Pounds Maximum Combined Trailer Length 81 Feet Maximum Trailer Lengths Front – 48 Feet*, Rear – 28.5 Feet Restricted to National Network * ATA suggests use of 53ft trailer
Heavy Intermediate Length Double 9-11 Axles, Maximum GVW – 129,000 Pounds Maximum Combined Trailer Length 81 Feet Trailer Lengths Front – 40 Feet, Rear – 24 Feet Restricted to National Network
Long Doubles 9+ Axles Maximum Trailer Length 45* Feet or 48* Feet Maximum GVW 129,000 Pounds Restricted to Interstate Highways * ATA suggests use of 53 ft trailers
Triples 7-8 Axles, Maximum GVW – 110,000 Pounds Maximum Trailer Lengths – 28.5 Feet Restricted to Interstate System Use of “Marshaling Yards”
Single Trailer Weight Increase Maintain current federal axle weight and bridge formula limits, but lift the 80,000 lbs GVW cap Single-trailer trucks with a GVW of 97,000 lbs Six axles, including a tridem axle on the rear of the trailer Maximum weight on the tridem axle limited to 51,000 lbs H.R. 1799
Benefits of the 6-Axle Truck Safety Similar operational characteristics to 5-axle Reduced VMT lowers accident exposure Fuel consumption and emissions reduced 17% per ton-mile after accounting for MPG loss Lower VMT should produce a small but measurable reduction in congestion Will bring down transportation costs, thus lowering overall U.S. manufacturing, agricultural and retail costs
Benefits of the 6-Axle Truck Pavement maintenance costs reduced $2.5 billion over 20 years Bridges State flexibility whether and where to allow trucks to operate will allow states to minimize cost impacts Shifting heavy trucks from local roads to Interstates will lower costs in some states Harmonization with international community
LCV Operations Beyond the Western Uniformity Region On a case-by-case basis, support local, state and regional efforts to improve truck productivity and expand LCV routes that meet appropriate safety standards. Lift the 80,000 lbs GVW cap for STAA doubles (double 28.5’ trailers). Allow double trailers longer than 28.5’ (e.g. double 33’ trailers).
Autohauler 10% Weight Tolerance More than 52% of motor vehicles sold minivans, pick-ups, SUVs. While larger vehicle sales are declining, sales of hybrids are increasing Large hybrid SUVs weigh up to 1,900 pounds more than non-hybrid version of the same vehicle Weight of a hybrid passenger car can exceed non- hybrid weight by more than four hundred pounds.
