Lowriders are legal in California. You can own one, build one, install hydraulic or air-bag suspension, and cruise public streets without running afoul of state law. Since January 1, 2024, cities and counties have been barred from banning cruising, and the suspension systems that define the culture have never been illegal to install. What California does regulate is how the car behaves on the road: how low the frame rides, how loud the exhaust is, what lights you run, and whether anything under the hood has been tampered with for emissions. Stay inside those lines and the car is street-legal.
Cruising Is Legal Statewide
Assembly Bill 436, signed by Governor Newsom on October 13, 2023, repealed the authorization that let local governments ban cruising and removed state-level restrictions on operating lowrider vehicles. It took effect January 1, 2024.1LA County Public Works. Car Cruising
That doesn’t mean anything goes at a cruise night. Cities and counties can still enforce general rules against noise, nuisance, and blocking traffic, and the statewide vehicle equipment rules below apply the same to a lowrider as to any other car.
The Ride-Height Rule
The statute that matters most to lowrider owners is California Vehicle Code Section 24008. It makes it unlawful to drive a passenger or 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 plain terms: while you’re driving, your frame cannot drop below the bottom of your rims.
This is the whole trick to legal hydraulics. Installing the setup is fine. Bouncing the car at a show or in a parking lot is fine. Dropping it on a public road is where the citation comes from. Most experienced owners raise the car to a compliant height before driving and only lay it out when the car is stationary.
Exhaust and Emissions
California regulates custom exhaust two ways: noise and tailpipe pollution.
CVC Section 27150 requires a working muffler at all times and prohibits cutouts, bypasses, and similar devices that let exhaust skip the muffler.3California Legislative Information. California Vehicle Code 27150 (2025) CVC Section 27151 bars any exhaust modification that pushes noise above 95 decibels on vehicles under 6,000 pounds.
The emissions side is stricter. CVC Section 27156 prohibits disconnecting, modifying, or removing any factory-installed pollution control equipment. Tamper with a catalytic converter or oxygen sensor and you’ll fail smog, and you won’t qualify for California’s repair cost waiver until the system is restored to factory spec.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 have your DMV registration suspended until the vehicle is corrected.5California Air Resources Board.

Lighting and Underglow
Underglow is legal 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 governs the broader color rules: anything visible from the front shows white or amber, anything from the rear shows red, with the usual exceptions for amber turn signals and white backup lamps.6Justia. California Code Vehicle Code – Fenders, Ornaments, and Television Flashing red or blue is reserved for emergency vehicles. Run them and you will get stopped quickly.
Tint and Fender Coverage
CVC Section 26708 restricts aftermarket tint on windshields and front side windows. The windshield can only be tinted above the manufacturer’s AS-1 line, and front driver and passenger windows must let at least 70 percent of light through. Rear windows can go darker, but if the back window is tinted, the car needs 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 need wider flares to stay compliant.8Justia. California Code Vehicle Code – Fenders, Ornaments, and Television
When the Car Is Legal But the Driving Isn’t
A perfectly compliant lowrider can still generate a serious citation if it’s driven in a way that triggers CVC Section 23109, which prohibits exhibition of speed on public roads. A conviction carries up to 90 days in county jail, a fine up to $500, or both.9California Legislative Information. California Code VEH 23109 Starting January 1, 2029, courts will also be able to suspend driving privileges for 90 days to six months when the violation is tied to a sideshow.
Hopping the car on a public street can be charged as exhibition of speed or reckless driving depending on the circumstances. At a sanctioned event or on private property, it’s not an issue. On a busy boulevard, it can be.
Tell Your Insurer About the Build
A standard auto policy insures the factory value of the vehicle, not the paint, chrome, and hydraulic work you added. Total the car and the payout reflects the depreciated value of the base vehicle. An agreed-value policy, where you and the insurer set a figure in advance that includes modifications, is the way to protect a serious build.
More important than the payout math: if you don’t disclose modifications and the insurer finds out after a claim, they can deny coverage for misrepresentation, even if the modification had nothing to do with the accident. Disclose everything when you set up or renew the policy.
What Happens If You Get Cited
Most equipment violations on a lowrider are correctable. You get a fix-it ticket, correct the problem, have a law enforcement officer or authorized inspection station sign the certificate of correction, and submit it to the court with a $25 fee per violation. Handle it by the due date and the ticket is dismissed.10California Courts. Fix-it Ticket – California Courts Self Help Guide
Ignore it and the correctable offense becomes a standard violation with higher fines. For exhaust violations under CVC Section 27151, a court can require a certificate of compliance, and failing to produce one within three months can result in a hold on your registration.
Emissions tampering sits in a different category. CARB penalties can reach $37,500 per violation and your registration can be suspended until the vehicle passes inspection.5California Air Resources Board.
