Size and Weight Reform is Necessary • Improved safety through lower VMT, operation of safer vehicles and shift to higher-class roads • Lower energy use and emissions • Meet customer demands for low-cost, efficient service • Insufficient infrastructure capacity to meet current or future freight needs

  3. Environmental Requirements = More Empty Weight • APU – 400 lbs • Federal weight exemption • 2002 engines – approx. 338 lbs • 2007 engines – approx. 275 lbs • 2010 engines – up to 500 lbs • TOTAL = 1,500+ lbs

  4. Regulations are Outdated • Some Interstate weight limits frozen in time for more than 50 years • No broad-based federal weight increase in 36 years  • 73,280 lbs to 80,000 lbs in 1974 • Interstate Highway weight limits increased 9% in 50 years despite more people and goods • 410% GDP growth • 76% population growth

  10. Five-axle Truck Weight Increase • Maintain current federal axle weight and bridge formula limits, but eliminate the 80,000 lbs GVW cap • STAA doubles and singles • Maximum 86,000 lbs based on bridge formula and axle weight limits • Kingpin setting requirements could limit increase

  11. Six-axle Truck Weight Increase • Single trailer only • Max. GVW of 97,000 lbs • Require a tridem axle limited to 51,000 lbs • Retain existing single and tandem axle limits • H.R. 1799
