California Reg 123 School Bus Registration Form

The Reg 123 form is the official California Department of Motor Vehicles (DMV) application for a temporary commercial registration or permit for privately owned school buses. This fillable PDF lets school districts, non‑profit education organizations, and contract operators register their vehicles quickly and securely.

What Is Reg 123?

Reg 123 (California Vehicle Code §9102.5) authorizes a temporary commercial registration for a school bus that is owned or operated by a private, non‑profit education organization. The permit is required before the bus can be used for transporting students on public roads.

Common Mistakes to Avoid

• Leaving required fields blank: The filler highlights missing information before you can submit.
• Using the wrong vehicle identification number (VIN): Verify the VIN on the vehicle registration card.
• Incorrect ownership details: The form must match the legal name of the owning organization.
• Submitting outdated insurance proof: Attach a current certificate of insurance that meets DMV requirements.

Where to Submit Your Completed Form

After you finish and sign the form, you can:

• Download the completed PDF and mail it to your local DMV office.
