California side mirror requirements come from Vehicle Code Section 26709: every registered motor vehicle other than a motorcycle must have at least two rearview mirrors, and one of them has to be mounted on the driver’s side. The second mirror can be the interior mirror, the passenger-side exterior mirror, or both. Certain situations, like towing or a blocked rear window, force you up to two exterior mirrors. A missing or broken mirror is usually a $25 fix-it ticket, but it can become a much larger problem if you’re in a crash.1California Legislative Information. California Vehicle Code 26709
The Two-Mirror Baseline
CVC 26709(a)(2) sets the floor for California-registered vehicles. Two rearview mirrors, one of them on the left. The statute doesn’t dictate where the second one goes, so an interior mirror plus a passenger-side mirror satisfies it, and so does a left mirror plus a right mirror with no interior mirror at all. Almost every modern car ships with all three, which is why most drivers never think about the rule until a mirror cracks or gets knocked off in a parking lot.
The specific thing to watch is the driver’s side. If your left exterior mirror is missing or broken, you’re out of compliance even if your interior and right-side mirrors are perfect. If the interior mirror or right-side mirror is what’s broken, you’re still legal as long as the other two work.
When You Need Mirrors on Both Sides
CVC 26709(b) tightens the rule in specific circumstances. In each of the following, you need working exterior mirrors on both the left and right, each showing at least 200 feet of highway behind you:1California Legislative Information. California Vehicle Code 26709
- Your rear view is blocked by cargo, vehicle design, or any other load. Panel vans, packed pickup beds, and loaded SUVs fall here.
- You’re towing a trailer, camper, or other vehicle that blocks the view through your back window. If the trailer is wider than your tow vehicle, factory mirrors often won’t reach around it and you’ll need extended or clip-on towing mirrors.
- You’re driving a bus or trolley coach. Both sides, always.
One carve-out surprises people. Under CVC 26709(c), passengers blocking the back window do not trigger the dual-mirror requirement. A minivan full of tall kids doesn’t put you in violation. Cargo does; people don’t.1California Legislative Information. California Vehicle Code 26709
The 200-Foot View
Every mirror the statute requires has to show at least 200 feet of highway behind the vehicle. A mirror that’s technically present but can’t deliver that view doesn’t satisfy the law. Cracked glass, heavy fogging, tarnish, or a loose mount that vibrates at freeway speed all undermine it. Officers don’t measure with tape, but a mirror shaking so hard you can’t identify the car behind you is an easy citation. Clean glass and tight mounting hardware handle this.
Motorcycles and Out-of-State Vehicles
CVC 26709(a)(1) treats motorcycles and vehicles registered outside California differently. Both need only one rearview mirror providing the 200-foot view. For a motorcycle, that’s typically a single handlebar or fairing mirror, though most riders run two by choice. Visitors driving in from another state meet the statute with one mirror, though the safety case for a second is obvious on California freeways.1California Legislative Information.

Doorless Jeeps and Broncos
Removing the doors on a Wrangler, Gladiator, or Bronco is legal, but the mirror rules don’t come off with them. The factory side mirrors on these vehicles are mounted on the doors, so pulling the doors pulls the mirrors. You need aftermarket replacements to stay legal.
Common options bolt to the A-pillar, mount into the upper door hinge, or attach to tubular half-doors built for open-air driving. Any of them work if they deliver the 200-foot rear view. Rolling down the coast with no doors and no replacement mirrors is one of the easier ways to collect a fix-it ticket, and the fix runs under $50.
Autonomous Vehicles
CVC 26709(d) exempts autonomous vehicles that cannot be operated by a human driver seated inside from the mirror requirements entirely, provided the exemption is consistent with applicable federal law. This is a narrow carve-out for fully driverless vehicles. Anything with a steering wheel and a human behind it still needs mirrors.1California Legislative Information. California Vehicle Code 26709
What a Mirror Ticket Actually Costs
A CVC 26709 violation is normally a correctable equipment violation, better known as a fix-it ticket. Under CVC 40610, the standard response to a mechanical equipment problem is a notice to correct rather than a straight citation, unless there’s evidence of fraud, persistent neglect, or an immediate safety hazard.2California Legislative Information. California Vehicle Code VEH 40610
To clear one, you fix or replace the mirror, get a law enforcement officer to sign the Certificate of Correction on the back of the ticket, and submit it to the court with a $25 dismissal fee. You typically have up to 30 days to do it.3California Courts. Fix-it Ticket Handled on time, $25 is the whole cost.
Ignore the ticket and the numbers change fast. An uncorrected equipment violation becomes a standard infraction, and California adds penalty assessments, a court security fee, a conviction assessment, and a surcharge on top of the base fine. On a $25 base, the total for an uncorrected violation can easily reach $190 to $200 or more depending on the court.
Why the Rule Matters After a Crash
The real financial exposure isn’t the ticket. California Evidence Code Section 669 creates a legal presumption of negligence when someone violates a statute, the violation causes injury, and the injured person is within the class the statute was designed to protect.4California Legislative Information. California Evidence Code 669
CVC 26709 exists to keep drivers from hitting the traffic they can’t see. If you cause a collision while driving with a broken or missing mirror, the other side doesn’t have to prove ordinary carelessness. They point at the violation, and the law presumes you failed to exercise due care. You can try to rebut that by showing you acted as a reasonable person would have in the circumstances, but that’s a difficult argument when the violation is as simple as a missing left mirror.
A $25 mirror you keep meaning to replace can end up as the central fact in a personal injury claim. Insurance adjusters treat a documented equipment violation at the time of a crash as a significant complication in the file, and the cheapest moment to solve the problem is before any of that starts.
