California Assembly Bill 1595 established a new legal category for recreational off-highway vehicles and introduced operating requirements covering helmets, restraints, passenger seating and minimum operator age.
Governor Jerry Brown signed AB 1595 on July 24, 2012, and most of its provisions took effect January 1, 2013. However, two controversial passenger provisions were changed before or shortly after the law became effective.
This article explains what AB 1595 originally did, how AB 1266 and Senate Bill 234 changed it and which provisions continue to affect California UTV owners.
What Did California AB 1595 Do?
AB 1595 created a separate legal definition for a “recreational off-highway vehicle,” commonly abbreviated as ROV. California Vehicle Code Section 500 defined an ROV as a motor vehicle meeting all of the following criteria:
- Designed by the manufacturer primarily for off-highway operation
- Steered with a steering wheel
- Equipped with non-straddle seating provided by the manufacturer
- Capable of traveling faster than 30 mph
- Powered by an engine with a displacement of no more than 1,000cc
The law was sponsored by the Recreational Off-Highway Vehicle Association, or ROHVA, and carried by Assemblyman Paul Cook. It adapted elements of ROHVA’s model state legislation to California’s existing off-highway vehicle laws.
The 1,000cc provision was especially significant. It brought an industry definition developed several years earlier into California law. That displacement boundary still affects how larger machines such as the Polaris RZR Pro R and RANGER XD 1500 are classified.

Operating Requirements Created by AB 1595
AB 1595 added Sections 38600 through 38604 to the California Vehicle Code. As originally enacted, those sections established five primary requirements for vehicles meeting the state’s ROV definition.
Operator Age
An ROV operator must be at least 16 years old unless directly supervised in the vehicle by a parent, guardian or another adult authorized by the parent or guardian.
Younger operators must also be able to reach and operate all vehicle controls as required by California law.
Helmets
The law required the operator and every passenger to wear a safety helmet meeting the standards established for motorcycles and motorized bicycles.
The helmet provision was subsequently amended so that the ROV-specific requirement applies on public lands. California State Parks says the helmet must comply with Federal Motor Vehicle Safety Standard 218 and carry the appropriate DOT labeling.
Seatbelts and Harnesses
Operators and passengers must wear a properly fastened seatbelt, shoulder belt or safety harness whenever the vehicle is moving.
Passenger Seating
The original law prohibited passengers from occupying a separate seating position that was not designed and provided by the vehicle manufacturer.
This provision immediately concerned owners of earlier two-seat UTVs that had been converted to carry rear passengers using aftermarket cages and seating systems.
Passenger Fit and Handholds
As originally written, AB 1595 required a passenger to sit upright with his or her back against the seatback, place both feet flat on the floorboard and grasp an occupant handhold while properly restrained.
The requirement that both feet remain flat on the floorboard caused particular concern because it could prevent children and shorter adults from riding even when they were properly restrained and otherwise safely positioned.
Why AB 1595 Became Controversial
The helmet and restraint requirements were broadly presented as safety measures. Most of the immediate opposition centered on the passenger-fit language and the prohibition against seating locations not supplied by the manufacturer.
The feet-flat requirement could exclude passengers solely because of their height. Meanwhile, the seating provision threatened the legality of existing UTVs that had been converted from two seats to four seats—a common modification before manufacturers offered today’s wide selection of factory four-seat models.
Industry representatives, dealers, aftermarket companies and UTV owners began seeking changes before all of the law’s requirements took effect.
AB 1266 Removed the Feet-Flat Requirement
Assembly Bill 1266 was introduced as an urgency measure to address the most immediate problems created by AB 1595.
Governor Brown signed AB 1266 on September 25, 2012. The legislation made two important changes:
- It eliminated the requirement that a passenger be able to place both feet flat on the floorboard.
- It delayed implementation of the manufacturer-provided seating restriction until July 1, 2013, allowing lawmakers more time to develop a permanent solution.
After AB 1266, passengers still had to sit upright with their backs against the seatback, use the appropriate restraint and be able to grasp an occupant handhold. Height alone was no longer determined by whether both feet could rest flat on the floor.
SB 234 Established the Model-Year Seating Rule
California Senate Bill 234 provided the longer-term resolution to the aftermarket seating controversy. Governor Brown signed SB 234 on August 27, 2013.
The resulting rule separates ROVs according to model year:
- Model year 2014 and newer: A passenger cannot occupy a separate seating location that was not designed and provided by the vehicle manufacturer.
- Model year 2013 and earlier: An added seating location may be occupied if the passenger remains fully contained within the vehicle’s rollover protection structure while the vehicle is being operated.
This distinction effectively grandfathered properly contained passenger seating in older UTVs while restricting the addition of new passenger positions in 2014-and-newer machines.
Replacing a manufacturer-provided seat with an aftermarket seat is not the same as adding a new seating location. California State Parks says factory seats may be replaced, but additional seating positions cannot be created on 2014-and-newer ROVs in areas the manufacturer did not design for passengers.
California ROV Requirements at a Glance
| Requirement | What Generally Applies |
|---|---|
| Operator age | At least 16 unless directly supervised in the vehicle by an authorized adult |
| Helmet | Operator and passengers must wear DOT-compliant helmets when operating an ROV on public lands |
| Restraints | Seatbelts, shoulder belts or safety harnesses must be properly fastened while the vehicle is moving |
| Passenger position | Passengers must sit upright against the seatback and be able to grasp an occupant handhold |
| Added seats on 2014-and-newer ROVs | Passengers cannot use seating locations not designed and provided by the manufacturer |
| Added seats on 2013-and-earlier ROVs | Permitted when the passenger remains fully contained within the rollover protection structure |
What Is an Occupant Handhold?
California law defines an occupant handhold as a factory or aftermarket device that provides support and helps keep an occupant’s arms and hands inside the vehicle. The steering wheel serves as the operator’s handhold.
California State Parks notes that a roll cage or seat cushion does not satisfy the intended function of a passenger handhold. A missing manufacturer-installed handhold may therefore need to be replaced if no other vehicle component provides the same safety function.
Does AB 1595 Apply to Every Side-by-Side?
No. These provisions apply specifically to vehicles meeting California’s legal definition of an ROV.
The definition’s 1,000cc maximum means some vehicles commonly marketed and recognized as UTVs or side-by-sides fall outside this particular classification. The 1,997cc Polaris RZR Pro R is the best-known example. California State Parks determined that it is not an ROV under Vehicle Code Section 500.
This does not exempt an over-1,000cc vehicle from every California OHV law or from rules imposed by a land-management agency, event promoter or private property owner. It means the vehicle is not governed by the provisions that apply specifically to the statutory ROV category.
Industry Support for AB 1595
Although the bill became controversial among riders, ROHVA and its member manufacturers supported the creation of a separate ROV category and its central helmet, restraint and safe-use provisions.
Kawasaki issued a contemporary statement explaining that the leading side-by-side manufacturers represented by ROHVA had supported the legislation. That statement remains useful as a record of the industry’s position when the law was enacted.

Why AB 1595 Still Matters
AB 1595 did more than add several safety rules. It placed an industry-created definition of a recreational UTV into California law.
That definition still determines which vehicles fall under California’s ROV-specific helmet, restraint and passenger requirements. It also demonstrates how the 1,000cc boundary developed by the UTV industry became influential far beyond voluntary vehicle standards.
The original law did not remain unchanged. AB 1266 removed the feet-flat requirement, and SB 234 established the model-year distinction for added passenger seating. However, the basic ROV classification and many of the operating requirements introduced in 2012 remain important to California riders.
For the state’s current guidance, review the California State Parks ROV frequently asked questions and its OHV laws and safety resources. Riders should also verify the rules for the specific public land, park or event where they plan to operate.
