All oversize loads entering the City of Stockton must conform to the requirements set by the California Department of Transportation (Caltrans) and the Stockton Public Works Department.

In general, any vehicle over 12 feet in width, 14 feet 6 inches in height, and within the super heavy weight class (over 125,000 lbs) should obtain an oversize load permit from the Stockton Public Works Department.

The City of Stockton, located in San Joaquin County, has specific regulations to ensure safe passage of oversize loads through its infrastructure, including the need to avoid certain roadways and bridges.

In Stockton, escort vehicles are required for loads exceeding 15 feet in width, 15 feet in height, or 120 feet in length. The escort vehicle must be equipped with appropriate warning lights and signs as per California Vehicle Code.

For super heavy or oversize loads that require a police escort, the Stockton Police Department must be contacted in advance to arrange for the escort. Fees for police escorts vary based on the number of officers required and the duration of the escort.

To apply for an oversize load permit in Stockton, applicants must submit their request through the California Department of Transportation's (Caltrans) oversize permit website or contact the Stockton Public Works Department directly. Required documentation includes detailed load specifications, proposed route, and travel dates.

Applicants should be prepared to provide additional information or modifications to their permit application as required by the City or Caltrans.

Time-of-day restrictions in Stockton typically prohibit oversize loads during peak traffic hours (7-9 am and 4-6 pm, Monday through Friday). Travel during holidays or special events may also be restricted.

Seasonal or weather-related restrictions may apply, particularly during heavy rainfall or when road conditions are deemed hazardous by the City or Caltrans.

Certain routes through Stockton are restricted for oversize loads, including those through historic districts or areas with low clearance bridges. The approved permit will specify the allowed route.

The base permit fee for oversize loads in Stockton is $50, with additional fees based on the size and weight of the load. Super heavy loads (over 125,000 lbs) incur a higher fee, ranging from $200 to $500, depending on the complexity of the route and the need for additional escorts or infrastructure protection.

Additional charges may apply for after-hours permit processing, police escorts, or other special services required for the safe transport of the oversize load.
