Comment: True: Truck do more damage

A fully loaded 18-wheeler does the equivalent wear & tear on a road as 30,000 passenger cars

This due to the significantly larger and more numerous deflection they cause in the pavement which creates cracks etc. Without 18 wheelers highways would last significantly longer and only need to be rebuilt to expand capacity, not due to wear. I'm not sure if gas-tax properly takes this into account or not...
