Compliance with Size and Weight Limits: California legal maximum width is 8'6", but California oversize permits allow widths up to 15 feet depending on the route. Height limits vary by highway, with loads over 14 feet requiring special permits. Length restrictions also apply, with loads up to 135 feet allowed under certain permits.

Safety Requirements: Loads exceeding standard dimensions may require escort vehicles, special lighting, and signage to ensure safe travel.

Restricted Travel Times and Routes: Oversize loads often face travel restrictions during peak hours and must follow approved routes to avoid infrastructure damage or traffic disruption.

Types of California Oversize Permits

California Single Trip Permits: Valid for one-time transport, typically lasting seven days, for loads within standard oversize limits37.
California Annual Permits: For frequent transporters moving oversize loads regularly within California.
Overweight Permits: For loads exceeding weight limits, with fees depending on axle configuration and weight distribution.
California Overhang Permits: Required when the load extends beyond the truck’s legal dimensions1.
California Superloads Permits: For loads exceeding the maximum standard dimensions (wider than 15 ft, taller than 17 ft, or longer than 135 ft), requiring special route surveys and approvals.
