Step-by-Step
How to Register a Trailer in California
All trailers towed on public roads in California must be registered with California Department of Motor Vehicles. Here is the standard registration process:
1
Gather Required Documents
You will need proof of ownership (Manufacturer's Certificate of Origin for new trailers, or the current title for used trailers), a valid photo ID, and payment. If the trailer was previously registered in another state, bring those documents as well.
2
Determine Your Trailer's GVWR
California uses a weight-based fee schedule - you'll need to know your trailer's Gross Vehicle Weight Rating (GVWR). This is usually listed on a tag on the trailer frame or tongue.

Attach License Plate & Keep Registration
Install your trailer's license plate in the designated bracket and ensure the plate light functions properly. Keep your registration certificate accessible when towing. Your trailer must also have proper functioning brake lights, turn signals, running lights, and safety chains.
