1. Regulatory Information & Disclaimers

The information, dimensional limits, permit fees, and pilot car triggers presented on OversizeLoadGuide (OLG) are compiled from publicly available Department of Transportation (DOT) manuals, statutory administrative codes, and the Federal Highway Administration (FHWA).

Motor carriers and pilot car operators must verify active temporary route restrictions, construction detours, and emergency bridge closures directly through official state permit portals prior to vehicle dispatch.
