You bought a dash cam, pulled it out of the box, and stuck it to the middle of your windshield. Seemed like the obvious spot. But California actually has specific rules about where a dash cam can go on your windshield, how big it can be, and even what it’s allowed to record. Mount it in the wrong place and you could get cited for a windshield obstruction under Vehicle Code 26708.
Dash cams are completely legal in California. The rules just come down to placement and size. If you know the three legal mounting zones and a couple of recording rules, you’re covered.
This guide walks you through California’s dash cam windshield laws so you can mount yours in the right spot, avoid a ticket, and make sure your footage actually holds up if you ever need it.
Are Dash Cams Legal in California?
Yes. Dash cams are legal in California for both personal and commercial vehicles. The state actually encourages their use because they promote safer driving and help establish fault in accidents.
But legal doesn’t mean “put it wherever you want.” California Vehicle Code Section 26708 is the law that governs what can and can’t go on your windshield. It’s the same statute that covers things like tinted windshields, stickers, and GPS mounts. Under that law, you can’t place any object on your windshield that obstructs or reduces your clear view of the road.
Dash cams get a specific exemption under Section 26708(b)(13), but only if they’re mounted in one of three approved zones and meet the size requirements. If your camera falls outside those zones, you can be cited even if the dash cam itself is perfectly legal to own.
Where You Can Legally Mount a Dash Cam on Your Windshield
California law gives you three legal spots on the windshield for a dash cam. Each zone has its own size limit.
Lower right corner (passenger side). This is the most common spot and gives you the most room. Your dash cam can sit within a 7-inch square area in the lower corner of the windshield on the passenger side. Most people choose this location because it stays out of the driver’s line of sight.
Lower left corner (driver side). You can also mount in a 5-inch square area in the lower corner nearest the driver. This spot works, but the camera has to be small enough to stay within that 5-inch zone and it must be outside the airbag deployment area.
Upper center of the windshield. A 5-inch square area at the center uppermost portion of the windshield is also legal. Many drivers mount their dash cam here, just behind the rearview mirror. It gives a wide, centered field of view and keeps the camera mostly hidden from the driver’s perspective. This is the spot our installers at Santa Clarita Auto Sound recommend most often.
Dashboard mount. You can always mount your dash cam directly on the dashboard instead of the windshield. There’s no size restriction for dashboard-mounted cameras because they don’t fall under the windshield obstruction rules. The tradeoff is that a dashboard mount sometimes gives you a less stable angle and may pick up more of the hood in the frame.
No matter which spot you choose, the camera cannot interfere with airbag deployment. If you’re not sure where your airbags are located, check your vehicle’s owner’s manual or ask your installer.
Size Limits for Windshield-Mounted Dash Cams in California
The size limits under California’s dash cam windshield laws are straightforward:
| Mounting Zone | Maximum Size |
| Lower right (passenger side) | 7-inch square |
| Lower left (driver side) | 5-inch square (outside airbag zone) |
| Upper center (behind mirror) | 5-inch square |
| Dashboard | No restriction |
For context, most consumer dash cams on the market today are well within these limits. A typical compact dash cam measures around 2 to 3 inches wide. Even the larger models with built-in screens rarely exceed 4 inches. So unless you’re mounting an oversized or commercial-grade camera, you’ll probably be fine on size.
The real issue is usually placement, not size. People get in trouble when they mount a normal-sized camera in a spot that isn’t one of the three approved zones, like the center of the windshield at eye level or on the driver’s side above the legal boundary.
California’s Audio Recording Rules for Dash Cams
This is the part that catches a lot of people off guard. Your dash cam probably records audio by default, and California has strict rules about that.
California is a two-party consent state under Penal Code 632. That means you cannot record a conversation unless everyone involved knows about it and agrees to it. If your dash cam has a microphone (and most do), you need to tell every passenger in your vehicle that the camera is recording audio. If someone doesn’t consent, you’re required to mute the audio recording.
The simplest way to stay compliant is to post a small, visible notice inside your car that says something like “Audio and video recording in progress.” CVC 26708(b)(13)(B) specifically requires this notice for vehicles equipped with video event recorders. A little sticker on the dashboard or sun visor handles the legal requirement.
If you’d rather skip the issue entirely, most dash cams let you turn off audio recording in the settings. You still get the video footage, which is the part that matters most for accident evidence anyway.
One more thing to know: these same rules apply if you have a dual-camera setup with an interior-facing lens. If you’re recording inside the cabin, everyone in the car needs to be aware of it.
What California Law Says About Dash Cam Footage
Under CVC 26708(b)(13), the legal definition of a “video event recorder” is a device that records in a continuous digital loop and saves footage when triggered by unusual motion, a crash, or manual activation. The statute references storing 30 seconds of data before and after a triggering event. In practice, most modern consumer dash cams record continuously and store hours of footage on their memory cards, well beyond the statutory minimum.
Footage is admissible in court. If you’re involved in an accident, your dash cam footage can be submitted as evidence. It carries real weight in proving fault, especially in cases where it’s your word against the other driver’s. Hit-and-run incidents, insurance fraud, and red-light disputes are all situations where dash cam footage can make or break your case.
But it can work against you too. If you were speeding, following too closely, or doing something else wrong at the time of a crash, the footage captures that as well. Dash cam recordings also log data like your speed, braking patterns, and G-force levels depending on the model. Keep that in mind. The footage is what it is, and both sides in a legal dispute can access it.
Police can access your footage. If law enforcement believes your dash cam captured evidence relevant to an incident, they can request or seize the footage. This is especially common in serious collisions or criminal investigations.
A dash cam protects you best when you’re driving well. And for most people, having a recorded account of what actually happened is far better than relying on memory and conflicting stories after a stressful accident.
Why Professional Dash Cam Installation Matters
You can stick a dash cam to your windshield in about five minutes. But there’s a big difference between a suction-cup mount with a cable draped across your dashboard and a clean, professional dash cam installation that’s wired into your vehicle properly.
Here’s what professional installation gets you:
Correct legal placement. An experienced installer knows California’s dash cam windshield laws and will mount the camera in one of the three approved zones, at the right size and position. No guessing, no risk of a windshield obstruction ticket.
Clean, hidden wiring. Instead of a power cable running from your cigarette lighter across the dashboard, a professional install tucks all the wiring behind your headliner, A-pillar trim, and dashboard panels. You don’t see any cables at all. It looks factory.
Hardwired power for parking mode. Many higher-end dash cams offer a parking surveillance mode that records when the car is off and detects motion or impact. This requires a hardwired connection to your vehicle’s electrical system with proper voltage monitoring so it doesn’t drain your battery. That’s not something you want to DIY unless you’re comfortable with automotive wiring.
Better reliability. Suction cups fall off. Adhesive mounts lose grip in California heat, especially during summer in the Santa Clarita Valley when temperatures inside a parked car can hit 150 degrees or more. A professional mount is secure and stays put.

Frequently Asked Questions
Where can I legally mount a dash cam on my windshield in California?
California Vehicle Code 26708 allows dash cams in three windshield locations: a 7-inch square in the lower right (passenger side) corner, a 5-inch square in the lower left (driver side) corner, or a 5-inch square in the upper center behind the rearview mirror. All placements must stay outside the airbag deployment zone. You can also mount on the dashboard with no size restriction.
Can I get a ticket for having a dash cam on my windshield in California?
Yes, if the camera is mounted outside one of the three approved zones or if it obstructs your view of the road. The citation falls under Vehicle Code 26708 for windshield obstruction. It’s typically treated as a correctable “fix-it” ticket, but the fine can reach around $200 if you don’t correct it. Staying within the legal mounting areas and size limits keeps you compliant with California’s dash cam windshield laws.
Does California require you to tell passengers about dash cam audio recording?
Yes. California is a two-party consent state under Penal Code 632, so everyone in the vehicle must know if the dash cam is recording audio. CVC 26708 also requires a visible notice posted in the car stating that conversations may be recorded. You can inform passengers directly or post a sticker on the dashboard or sun visor. If someone objects, you need to mute the microphone. Turning off audio in the dash cam settings is the easiest way to avoid any issues.
Can dash cam footage be used as evidence in California?
Absolutely. Dash cam footage is admissible in California courts and is treated similarly to other types of private security recordings. The footage can help establish fault in accidents, catch hit-and-run drivers, and counter fraudulent claims. Keep in mind that the footage can also be used against you if it captures your own driving errors.
How much does professional dash cam installation cost in Santa Clarita?
Most of our customers at Santa Clarita Auto Sound spend between $75 and $250 for professional dash cam installation, depending on the camera type and whether they want hardwired parking mode.
