HB 4126
Plain-language analysis
Generated analysis, not an official summary or legal advice. Confirm with linked Oregon documents.
The measure directs ODOT to biennially recommend a per-mile road usage charge rate and requires the first report by January 31, 2027. It mandates that the report break down total vehicle miles traveled by specific weight classes (10,000 to 26,000 pounds in 2,000-pound increments) and establish maintenance metrics. The measure takes effect immediately upon passage via an emergency clause, requiring General Fund appropriation for initial staffing and consulting costs.

If adopted, HB 4126-2 would require the Oregon Department of Transportation (ODOT) to submit a biennial report recommending a per-mile road usage charge rate, mandating that the vehicle miles traveled (VMT) estimate in that report be disaggregated by weight classes for vehicles between 10,000 and 26,000 pounds. The amendment sets the first report deadline to January 31, 2027, and declares an emergency. Materially, this imposes a General Fund cost of approximately $796,215 in the 2025-27 biennium for ODOT to hire staff and consultants to develop metrics and collect disaggregated data, with no direct revenue impact.
