In America, do truck operators not have to pay for use of roads? Or are you talking about illegal activity?

- shantly 7y agoThe heavier the vehicle, the more damage it does, ~exponentially. Freight trucks use more fuel (and so, fuel taxes) and have more fees and such but nowhere near enough to make up for the extra damage they do.
- jcampbell1 7y agoIn the US we have maximum weight limits and it is enforced with weigh stations. I have wondered if tire pressure limits would be more effective at preserving the roads. Cars put about 35psi on the roads and trucks put 80-100psi.
- robocat 7y agoIt isn't as simple as X kPa does Y damage. Damage also occurs due to dynamic loading, which depends upon suspension, tire weight, weight shifts between axles, and braking action (frictional horizontal loads).
- rleigh 7y agoRoad damage is proportional to the fourth power of the axle weight. Adjusting the tyre pressures won't have any appreciable effect. Halving the maximum lading weight would reduce the damage by a factor of sixteen.
- CodeWriter23 7y agoYes they pay extra road tax for that. Politicians quite commonly spend the money on stuff other than road maintenance. But an example of a shipping company externalizing its costs to the public, I saw a photo in NYC of two guys and a delivery truck for one of the carriers sorting packages on the sidewalk, creating a public nuisance by blocking the sidewalk and access to crosswalks. Saves the company costs on warehouse time/space to sort before loading.
