Lowriders are legal in California. Owning one, building one, and installing hydraulic or air-bag suspension have never been illegal, and since January 1, 2024, cities and counties can no longer ban cruising either. What can still get you cited are specific driving conditions and modifications: how low the frame sits while the car is moving, how loud the exhaust runs, what colors your lights show, and how much of the tire sticks past the fender. The car is legal. The details are where tickets happen.
Cruising Is No Longer Something Cities Can Ban
Assembly Bill 436, signed by Governor Newsom on October 13, 2023, took effect January 1, 2024. It repealed the authorization for any local government to prohibit cruising and removed statewide restrictions on operating lowrider vehicles.1LA County Public Works. Car Cruising For decades, cities had used anti-cruising ordinances to discourage lowrider gatherings; those ordinances no longer have legal footing.
AB 436 does not override traffic laws. Cities can still enforce noise ordinances, block-the-box rules, and other general nuisance and safety laws that might apply during a cruise. The statewide equipment rules below still apply too.
The Ride-Height Rule That Catches Most Lowriders
California Vehicle Code Section 24008 is the statute lowrider owners need to know cold. It makes it unlawful to drive a passenger vehicle or a commercial vehicle under 6,000 pounds if any part of the vehicle other than the wheels sits closer to the road than the lowest point of any wheel rim touching the ground.2California Legislative Information. California Vehicle Code 24008 (2022) In practice: while you are driving, no part of the frame can be lower than the bottom of the rim.
This is what makes hydraulic setups a gray area for people who don’t understand the rule. Installing hydraulics is legal. Bouncing the car while parked or at a show is legal. Driving down the street with the suspension dropped below rim height is not. The standard approach is to raise the car to a compliant ride height before driving and only drop it when the car is stopped.
Exhaust: Noise and Emissions Are Regulated Separately
Two sets of rules apply to exhaust work, and they carry very different consequences.
CVC Section 27150 requires every vehicle with an internal combustion engine to have a working muffler at all times. Cutouts, bypasses, and similar devices that let exhaust gases skip the muffler are prohibited outright.3California Legislative Information. California Vehicle Code 27150 (2025) CVC Section 27151 sets a 95-decibel ceiling for modified exhaust on vehicles under 6,000 pounds.
Emissions tampering is the harder rule. CVC Section 27156 prohibits disconnecting, modifying, or removing any factory-installed pollution control equipment. If your exhaust work touches the catalytic converter or oxygen sensors, you’ll fail your smog check, and you won’t qualify for California’s repair cost waiver until the tampered systems are restored to factory configuration.4California Bureau of Automotive Repair. Smog Check Reference Guide 2025 The California Air Resources Board can impose penalties up to $37,500 per violation and suspend DMV registration until the vehicle is corrected.5California Air Resources Board.

Underglow and Lighting
Underglow is legal in California within limits. Under CVC Section 25400, underbody lights must emit a diffused, nonglaring light of no more than 0.05 candela per square inch. They cannot flash, and no red light can be visible from the front of the vehicle.
CVC Section 25950 sets the broader color rule: any lamp or reflector visible from the front of the vehicle must show white or amber; those visible from the rear must show red, with exceptions for amber turn signals and white backup lamps.6Justia. California Code Vehicle Code – Fenders, Ornaments, and Television Flashing blue and red are reserved for emergency vehicles.
Window Tint and Wheel Coverage
CVC Section 26708 limits aftermarket tinting on windshields and front side windows. The windshield can only be tinted above the manufacturer’s AS-1 line, and the front driver and passenger windows must let through at least 70 percent of light. Rear windows and back side windows can be darker, but if the rear window is tinted, the car must have side mirrors on both sides.7California Legislative Information. California Vehicle Code 26708 (2025)
CVC Section 27600 requires fenders, covers, or splash guards at least as wide as the tire tread. If your wheels stick out past the fenders, you’ll need wider fenders or flares to stay compliant.8Justia. California Code Vehicle Code – Fenders, Ornaments, and Television
Legal Car, Illegal Driving
A perfectly compliant lowrider can still put its driver in front of a judge. CVC Section 23109 prohibits exhibition of speed on public roads, punishable by up to 90 days in county jail, a fine up to $500, or both.9California Legislative Information. California Code VEH 23109 Hopping a car on a public street can be charged as exhibition of speed or reckless driving depending on the circumstances. The same hop at a sanctioned event or on private property raises no such issue.
Insurance Is the Other Legal Risk
A standard auto policy covers the factory value of your vehicle, not the thousands of dollars you have in paint, hydraulics, or chrome. If the car is totaled, a standard policy pays the depreciated value of the base car and nothing for the build. An agreed-value policy, where you and the insurer set a pre-determined value for the car including modifications, is the fix.
Failing to disclose modifications is a bigger problem than underinsuring. If you’re in an accident and the insurer finds undisclosed or illegal modifications, it can deny the claim entirely on the basis of misrepresentation, even if the modification had nothing to do with the crash. Disclose every modification when you write or renew the policy.
What a Ticket Actually Costs
Most lowrider equipment violations are correctable offenses, which means a fix-it ticket rather than a mandatory fine. You correct the problem, take the car to a law enforcement officer or authorized inspection station to sign off, and submit the signed certificate of correction to the court with a $25 fee per violation.10California Courts. Fix-it Ticket – California Courts Self Help Guide Handled by the due date, the ticket is dismissed.
Ignoring the ticket is what turns it costly. Missing the correction deadline converts the fix-it into a standard violation with higher fines. For exhaust violations under CVC Section 27151, a court can require a certificate of compliance, and failing to provide one within three months can put a hold on your registration.
Emissions tampering is the outlier. CARB fines can reach $37,500 per violation and registration can be suspended until the car passes inspection.5California Air Resources Board. Advisory 292 – CARB Enforcement Advisory That’s the one modification category where the difference between doing it right and doing it wrong can take the car off the road for a long time.
