State lawmakers who wish to raise additional transportation revenue through greater use of toll roads, fare increases on transit vehicles, or motor vehicle fee impositions or increases often face stiff resistance from motorists, transit riders and commercial interests. Many of the arguments against such fee increases concern fairness. Motorists do not want to be unfairly burdened with tolls and forced to supplement other transportation expenses throughout the state. Some argue that trucks and commercial motor vehicles (CMVs), which are heavier than passenger vehicles, should pay more because they cause more damage to the roads. Truck and CMV operators, however, often argue that they are unfairly punished and asked to pay too much for transportation expenses.
