What California Drivers Need to Know About Unsafe Passenger Riding Laws
California Vehicle Code § 21712 addresses unlawful riding in a vehicle and prohibits certain unsafe passenger practices on California roads. The law focuses on situations where people ride in parts of a vehicle that are not designed or intended for passengers, as well as situations involving passengers riding inside vehicle trunks.
Many people have questions about this law, especially when it comes to riding in pickup truck beds, sitting in cargo areas, or allowing passengers to ride in unusual locations. While some situations may seem harmless—such as traveling a short distance or moving slowly—California law places restrictions on how passengers may be transported.
Understanding California Vehicle Code § 21712 can help drivers and passengers recognize unsafe riding situations and better understand potential traffic violations.
What Is California Vehicle Code § 21712?
California Vehicle Code § 21712 generally prohibits a person from riding on a portion of a vehicle that is not designed or intended for passenger use. It also prohibits drivers from knowingly allowing someone to ride in those unsafe locations.
The law includes several important provisions:
- Drivers may not knowingly allow passengers to ride on parts of a vehicle that are not designed for passengers.
- Passengers may not ride on portions of vehicles that are not designed or intended for passenger use.
- Drivers may not knowingly allow someone to ride inside the trunk of a vehicle.
- People may not ride inside the trunk of a motor vehicle.
The purpose of the law is to reduce injuries caused by passengers riding in areas where they are not properly protected.
Why Does California Prohibit Unsafe Riding?
Vehicles are designed with specific areas for passenger transportation. Seats, seat belts, protective structures, and safety systems are created to help protect occupants during sudden stops, collisions, or other dangerous driving situations.
Areas such as open cargo spaces, exterior vehicle surfaces, or trunks generally do not provide the same protections as passenger compartments.
For example, a person sitting in the open bed of a pickup truck may have no restraint system and may be thrown from the vehicle during a crash or sudden maneuver. Even at lower speeds, an unexpected turn or stop can create serious safety risks.
California Vehicle Code § 21712 aims to prevent these foreseeable dangers by restricting unsafe passenger locations.
Is It Illegal to Ride in the Back of a Pickup Truck in California?
One of the most common questions about Vehicle Code § 21712 is whether passengers can legally ride in the bed of a pickup truck.
The answer depends on the circumstances.
California law generally prohibits riding on portions of a vehicle that are not designed or intended for passenger use. However, the law includes exceptions. For example, subdivisions (a) and (b) do not apply in certain situations involving employees performing necessary duties or people riding completely within or upon vehicle bodies in spaces intended for carrying loads.
This means the legality of riding in a truck bed depends on factors such as:
- The design of the vehicle
- The location where the person is riding
- Whether the area is intended for carrying people or cargo
- Whether a legal exception applies
Even when a situation may fall within an exception, drivers should consider the safety risks involved because cargo areas usually do not provide the same protections as passenger seats.
Examples of Situations That May Raise Issues Under Vehicle Code § 21712
Passenger Riding in an Open Truck Bed
A driver allows several friends to sit in the open bed of a pickup truck while driving on public streets.
Because the truck bed is generally designed for cargo rather than passengers, this situation may raise concerns under Vehicle Code § 21712 unless an applicable exception applies.
Riding on the Exterior of a Vehicle
A person sits on the hood, roof, side step, or another exterior portion of a moving vehicle.
These locations are generally not designed for passenger transportation and create a risk that the person could fall or be thrown from the vehicle.
Allowing Someone to Ride in a Trunk
A driver allows a person to travel inside the trunk of a car.
California law specifically prohibits both allowing someone to ride in a vehicle trunk and riding inside the trunk.
Who Can Receive a Citation Under Vehicle Code § 21712?
The law can apply to both drivers and passengers.
A driver may violate the law by knowingly permitting someone to ride in a prohibited area of the vehicle. A passenger may also violate the law by riding in a location that is not designed or intended for passenger use.
For example:
- A driver knowingly allows a person to sit in an unsafe cargo area.
- A passenger chooses to ride on an exterior portion of a vehicle.
- A person rides inside a vehicle trunk.
The specific facts of each situation determine how the law may apply.
What Are the Penalties for Violating California Vehicle Code § 21712?
The penalties depend on which part of the law was violated.
Violations involving riding in a prohibited vehicle location are generally treated as traffic infractions. The consequences may include fines and related court assessments.
Vehicle Code § 21712 specifically provides penalties for violations involving riding in a vehicle trunk:
- First violation: $100 fine
- Second violation within one year after a prior conviction: $200 fine
- Third or subsequent violation within one year after two or more prior convictions: $250 fine
Additional court-related fees and assessments may also apply depending on the circumstances.
Is Riding in a Truck Bed Always Dangerous?
Pickup truck beds are useful for transporting cargo, but they are generally not built with passenger safety features.
Unlike passenger compartments, truck beds typically do not include:
- Seat belts
- Passenger seats
- Side-impact protection
- Airbags
- Occupant restraint systems
A collision, sudden braking event, or loss of control could cause passengers in an open cargo area to be seriously injured.
The safety concerns behind Vehicle Code § 21712 are based on the increased risk created when people ride outside areas designed for passengers.
How Is Vehicle Code § 21712 Different From Seat Belt Laws?
Vehicle Code § 21712 and California seat belt laws address different issues.
Seat belt laws generally focus on whether occupants are properly restrained while sitting in approved passenger seating areas.
Vehicle Code § 21712 focuses on whether a person is riding in a location that is not intended for passengers.
For example:
- A person sitting in a regular passenger seat without wearing a seat belt may involve a seat belt violation.
- A person riding in an unsafe cargo area may involve Vehicle Code § 21712.
