Heavy Haul Permitting Methodology & Data Architecture
The OversizeLoadGuide (OLG) compliance platform cross-references statutory administrative rules across all 50 State Departments of Transportation, the Federal Highway Administration (FHWA), and the Specialized Carriers & Rigging Association (SC&RA).
1. Primary Data Sources
- Federal Weight Limits: 23 CFR Part 658 & 23 U.S.C. ยง 127 (Federal Bridge Formula B).
- Commercial Driver & Hauling Rules: Federal Motor Carrier Safety Administration (FMCSA) Title 49 CFR Part 383.
- State DOT Oversize Offices: Official administrative code permit manuals from agencies including TxDMV, Caltrans, FDOT, ODOT, PennDOT, and IDOT.
- Pilot Car Standards: SC&RA Pilot Car Best Practices and state-certified escort training curricula (Washington, Utah, Florida, Oklahoma).
2. Telemetry Computation Standards
Our Evaluator Rig computes escort requirements by determining the most restrictive statutory trigger between the selected state's 2-lane road and 4-lane divided highway tables. Widths above 12'0" (2-lane) and 14'0" (4-lane) automatically trigger escort warnings.
