Interstate vs. Intrastate Trucking: Insurance Rules Every Carrier Must Know in California 

Understanding the difference between interstate and intrastate trucking is essential for California carriers. Whether you’re an owner-operator, manage a fleet or run a commercial trucking company, knowing how insurance requirements change based on your operations can help you stay compliant and financially protect your business.

What’s the Difference?

Interstate trucking often means transporting goods and materials across state lines or even outside the country. Intrastate trucking, on the other hand, involves hauling loads solely within California’s borders. This distinction matters because it determines which regulations and insurance rules apply to your business.

Insurance Requirements for Interstate Trucking

If your trucks cross state lines, you must comply with federal regulations set by the Federal Motor Carrier Safety Administration (FMCSA). Key insurance requirements include:

• Minimum liability coverage, which varies based on cargo type and vehicle size (often higher than state minimums)
• Proof of insurance filings, such as the MCS-90 endorsement
• Additional filings for hazardous materials or passenger carriers

Interstate carriers typically must also register with the Unified Carrier Registration (UCR) system and must understand and comply with insurance requirements in other states in which they operate.

Insurance Rules for Intrastate Trucking

Carriers operating only within California are regulated by the California Department of Motor Vehicles (DMV) and the California Public Utilities Commission (CPUC). Insurance requirements for intrastate trucking typically include:

• State-mandated minimum liability coverage, which may differ from federal standards
• Proof of insurance filings with the DMV or CPUC, such as Form MCP-65
• Additional coverage for certain cargo types or vehicle classes

It’s important to note that California’s insurance minimums may be lower than federal requirements, but failing to meet the correct standard can result in fines or suspension of operating authority.
