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).
