Some private gains are created by shifting costs onto others. The Accord prices those costs at the source: carbon, methane, speculation, systemic financial risk, pavement destruction, public-health harms, aquifer depletion, interchange extraction, and labor-market undercutting.
Heavy commercial vehicles cause pavement damage that scales with the fourth power of axle load. A typical 80,000-pound 5-axle truck imposes approximately 9,600× the marginal pavement cost of a typical passenger car (per FHWA Highway Cost Allocation Study) — yet fuel-tax-based road financing prices the truck at roughly 4–5× the passenger-car rate. The ratio of pavement-damage to fuel-tax-payment is so far off that state DOTs and general taxpayers absorb the gap.
The undercharging produces two structural failures. First, fiscal: federal and state highway trusts run chronically short of resources to maintain existing infrastructure, let alone to expand capacity. Second, modal: the under-priced trucking option distorts freight-mode choices toward road over rail and intermodal options that have lower pavement-damage and emissions profiles per ton-mile.
Mileage-weight road-use fee scaled by axle load. Telemetry-based collection (existing FMCSA-required electronic logging device infrastructure makes mileage-by-axle-load data available at the per-vehicle level).
Rate calibrated to the published FHWA pavement-damage allocation. Revenue routes to a federal-state highway trust shared with the affected jurisdictions.
Heavy commercial fleet operators in proportion to axle-mile-load product. Largest impact on long-haul over-the-road trucking; meaningful impact on regional heavy-freight; modest impact on local heavy-vehicle use (concrete trucks, dump trucks, etc.).
Passenger vehicles continue under existing fuel-tax architecture. Light commercial vehicles face de minimis additional fee. Local-use heavy vehicles (school buses, fire engines, etc.) operate under specific carve-outs.
Pending canonical scoring.
Heavy-vehicle road-use revenue has two effects. Direct fiscal: meaningful federal-state highway-trust funding tied to actual damage caused. Indirect modal: the price signal shifts long-haul freight at the margin toward rail, intermodal, and shorter trucking corridors — reducing aggregate pavement damage even before the fee revenue is collected.

- ELD-data tampering
- FMCSA-required electronic logging device infrastructure has existing tamper-detection. The road-use fee rides on already-deployed compliance infrastructure.
- Cross-state arbitrage
- Federal collection routed to federal-state trust avoids the state-by-state shopping pattern that today produces gaps.
- Empty-leg gaming
- Fee scales with axle load AND mileage, including unloaded mileage at lower per-mile rate. Empty-leg routing does not avoid the fee proportionally.
- Carbon fee
- Heavy commercial vehicles also pay carbon fee on diesel consumption. The two instruments price different externalities (pavement damage vs CO₂ emissions) without double-counting.
- Federal-state highway trust
- Revenue routing to existing trust infrastructure shared with state DOTs.
