All oversize loads entering the City of Union City, located in Alameda County, must conform to the requirements set by the California Department of Transportation (Caltrans).

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

The permit process involves coordination with the City's Traffic Operations team to identify the most suitable route, taking into account factors like road conditions, traffic volume, and potential impacts on local events or construction projects.

Escort vehicles are required for oversize loads exceeding 16 feet in width or 18 feet in height on highways and major roads within Union City. The escort vehicle must be equipped with proper signage and lighting as per Caltrans guidelines.

For loads requiring a police escort, applicants must contact the Union City Police Department at least 72 hours in advance to arrange for escort services. Additional fees apply for police escorts, which vary based on the duration and complexity of the escort.
