Alternative-Fueled Vehicles: Potential Impact of Exemptions From Transportation Control Measures

Pursuant to a congressional request, GAO examined the implications of exempting alternative-fueled vehicles (AFV) from transportation control measures (TCM), focusing on: (1) AFV exemptions' effects on TCM; (2) AFV exemptions' effectiveness in encouraging AFV purchases and alternative fuel use; (3) government and industry views on whether the exemption program should be federally or state controlled; (4) the general public's reaction to the exemptions; (5) the exemptions' impact on TCM enforcement; and (6) specific types of AFV that would be eligible for exemption.
