California Specialty Vehicle Registrations

Beyond the standard passenger-car registration, California's DMV manages a long list of specialty vehicle classifications. Each has its own paperwork, plate type, and fee structure — and a few have rules that catch newcomers off guard, especially around off-highway vehicles and trailers.

Trailers

California requires almost every trailer to be registered. The basic categories:

• Utility trailers — small open trailers (under 1,500 pounds with no brakes). California issues a "permanent" Trailer ID under the Permanent Trailer Identification (PTI) program with no recurring renewal fee — only an initial registration and a $10 every-five-years renewal.
• Larger trailers (1,500-10,000 pounds) — registered with annual renewal, similar to passenger vehicles, often subject to a one-time inspection at first titling.
• Camp trailers and travel trailers — registered as park trailers if permanently affixed to a site; otherwise as standard travel trailers with their own VIN.

Motorcycles

California registers motorcycles using the same REG 343 application as cars, with annual renewal cycles. Fee structure is similar but typically lower than passenger cars. Helmet laws apply universally — California is a "universal helmet" state, meaning every rider and passenger must wear a DOT-compliant helmet at all times. See our motorcycle license page for the licensing path.

Mopeds and motor-driven cycles

California issues a special moped plate for vehicles that meet the moped definition — primarily 50cc-and-under engines with a maximum design speed of 30 mph. The plate is permanent and cheaper than a standard motorcycle plate. Vehicles above 50cc or with higher design speeds are registered as full motorcycles.

Off-highway vehicles (OHVs)

ATVs, dirt bikes, side-by-sides, and dune buggies that are not street-legal are registered through California's OHV "Green Sticker" or "Red Sticker" program:

• Green sticker — issued to vehicles that meet California air-quality standards and may be used year-round at OHV areas.
• Red sticker — issued to non-compliant vehicles, with seasonal use restrictions in California state OHV areas.

OHV registrations are valid for two years and renewed by mail or online through the DMV. Vehicles operated only on private property of the owner do not require an OHV registration.

Historic and Year-of-Manufacture plates

California offers two specialty plate options for older vehicles:

• Historic Vehicle — for vehicles 25 years and older that are operated mainly for exhibition, parades, club activities, and similar uses. Limited daily-driver use is restricted.
• Year of Manufacture (YOM) — vehicles manufactured in 1980 or earlier can use authentic California license plates from the year of manufacture, after passing a verification by a DMV YOM examiner. The YOM plate retains a permanent registration and replaces the standard plate.

Motorhomes and RVs

Self-propelled motorhomes are registered as passenger vehicles with VLF based on weight. California treats motorhomes over 10,000 pounds GVWR with stricter requirements: drivers may need a Class A or B non-commercial license, and registration fees scale up sharply.

Out-of-state non-resident

If you're a California college student maintaining residency in another state, or a military service member stationed in California, you can keep your out-of-state registration as long as your home-state insurance and registration remain current. Non-residents who establish California residency (job, voter registration, lease) have 20 days to re-register their vehicle in California.
