How California tint law and DMV rules affect every Los Angeles shop job
California tint law sets film darkness by window position, and Los Angeles shops document exemptions, meter readings, and waivers before film goes on.
What to take away
- California Vehicle Code section 26708 governs film darkness and window position on every vehicle registered in the state, and it covers coatings as well as film.
- Section 26708.5 lists the exemptions. A medical exemption needs a written statement from a licensed physician, carried in the vehicle, not a verbal claim at the counter.
- The DMV checks tint only at specific inspection points, such as out-of-state verification and revived registration. Routine enforcement runs through law enforcement citations.
- A signed waiver records that the customer accepted the risk. It does not make an illegal shade legal.
- A tint meter reading, a photo of the finished glass, and a copy of both statutes in the job file are what a shop produces when a citation is contested.
What section 26708 restricts
Section 26708 of the California Vehicle Code is the statute a Los Angeles shop works against on every job. It limits film by window position, not by a single statewide number.
VLT Limits by Window Position
Windshield
- Allowed film
- Top strip or clear
- Clear ceramic
- Legal if standard met
- Dark film
- Not allowed
- Statute
- 26708
Front Side
- Allowed film
- 70% VLT minimum
- Clear ceramic
- Legal above 70%
- Dark film
- Below 70% illegal
- Statute
- 26708
Rear Side / Back
- Allowed film
- Darker if 2 mirrors
- Clear ceramic
- Legal
- Dark film
- Only with 2 mirrors
- Statute
- 26708
The windshield takes no film except a strip at the top or a clear, colorless product that meets the standard. Front side windows must pass at least 70 percent visible light transmission. Rear side windows and the back glass can go darker if the vehicle carries an outside mirror on both sides.
The statute reaches sunscreening material, not just applied film. Any adhesive or coating that cuts light transmission falls under the same limit. A clear ceramic film that blocks heat and stays above 70 percent VLT sits inside the rule. A dark film that drops below it does not.
Measure with a tint meter and write the reading on the work order. That number is the evidence if the driver contests a citation. Read the full text at California Code, VEH 26708.
Check the mirrors before cutting film. A tinted back glass with one outside mirror turns a compliant job into a violation, and the customer will bring the ticket back to you.
Section 26708.5 and the exemptions
Section 26708.5 creates the exceptions. The one Los Angeles shops see most is medical: a written statement from a licensed physician identifying the patient and the need for reduced light exposure.
Which Exemption Applies
Medical need claimed?
Signed physician statement required
No medical exemption
That statement does not legalize any shade the customer wants. It travels with the driver and gets presented at a traffic stop. Treat a verbal claim of medical need as no paperwork at all, and do not cut film until the signed statement is in hand.
The commercial exemption is narrower than most customers assume. It covers vehicles regulated by the California Public Utilities Commission, such as buses and limousines. A standard rideshare car does not qualify, so ask for the registration class before recommending a shade.
Section 26708.5 also allows clear, colorless film on the windshield when it meets the standard and sits below the AS-1 line. Verify the product against that standard before installing it. A clear film that fails the test still draws a citation.
The exemptions are not self-executing. The driver must carry the documentation. Your job is to say so out loud, hand over a copy, and keep one in the file. For how other states handle the same question, see our state-by-state question.
Where the DMV actually checks tint
The California DMV does not inspect film at every renewal. It checks at defined points: verification of a vehicle arriving from another state, revived registration on a vehicle that sat non-operational, and salvage or reconstructed inspections.
When the DMV Checks Tint
- Out-of-state vehicle verification
- Revived non-operational registration
- Salvage inspection
- Reconstructed vehicle inspection
- Dealer sales off the lot
A shop that tints a car before the owner clears those steps can hand back a problem. Advise customers new to California to finish registration first. The registration process and its forms are on the California DMV site.
For vehicles already registered, enforcement runs through law enforcement, not the DMV. A fix-it ticket goes to court. The driver removes the film, an officer signs the ticket, and the shop that installed it often gets the removal call. Charge for removal and keep the original installation record.
One pitfall sits next to this. A shop that also flips vehicles may cross into dealer territory, and a dealer cannot sell a vehicle with tint that violates section 26708. Confirm dealer licensing with the DMV before you sell anything off the lot.
Paperwork to keep in every job file
The physician's statement is the first document. Keep a current, signed copy with the license number and a contact for the physician. A note on the work order is not a substitute.
The waiver is the second. It records that the customer understood the legal limits and accepted the risk. It does not authorize an illegal shade, and it will not survive a claim that the shop misrepresented the law.
Write the film type, the VLT percentage, and the windows tinted into the waiver. Add a removal clause: state that removal after a citation is a paid service unless the shop chooses otherwise. That one line settles most return-visit arguments.
Keep a copy of sections 26708 and 26708.5 in the file as well, and run the whole set as a standing procedure. This is the core of a working compliance checklist.
Job File Paperwork
- Signed physician's statement on file
- Signed waiver with film type and VLT
- Tint meter reading on work order
- Copies of sections 26708 and 26708.5
- Photo of each finished tinted window
- Customer told in writing to carry exemption
- Note if mirrors or equipment missing
Film choice and bay scheduling in Los Angeles heat
Valley heat drives the film conversation. Customers want the cabin cooler without going darker, and a ceramic film at 70 percent VLT delivers that while staying legal on front side windows. A shop that stocks only dyed film loses those jobs to the shop down the street.
Long commutes add a second pressure. More hours behind the glass means more sun on the driver's side, which is why clear or lightly tinted ceramic on the windshield comes up so often. California restricts that film, so explain the standard rather than promising a result.
Heat also sets the schedule. Film needs to cure, and a bay in direct July sun will bubble a rushed install. Book tint work into the morning or late afternoon, and give the film its cure time before the car leaves. A one-hour promise in August buys you a comeback.
Order of work matters when a customer wants a wrap and tint together. Tint first, then wrap, or mask the glass edges carefully. A wrap that runs over the window edge interferes with film installation and with any later removal. Build the sequence into your inspection protocol so it happens the same way every time.
Commercial vehicles and fleet work
Vans and trucks make up a real share of Los Angeles tint demand, for privacy and for heat. Commercial vehicles can fall under different allowances, and the rules that apply to a fleet are not the rules that apply to a personal car.
Do not guess at a fleet customer's requirements. FMCSA sets marking and inspection rules for interstate commercial vehicles, and the relevant state authority sets the rest. Point the customer there and let them confirm before you quote the job.
Weight matters. A vehicle with a gross vehicle weight rating over 10,000 pounds may sit under different tint allowances, so check the registration class against the vehicle code before recommending film.

How a job survives a citation
Documentation is the whole defense. Every job file should hold the signed waiver, the meter reading, the exemption if one applies, and a copy of the statutes. If the driver is stopped, the paperwork answers the officer. If the shop is investigated, the file shows good faith.
Train staff to tell section 26708 from section 26708.5 at the counter. They should be able to explain the medical exemption, explain the waiver, and know when to turn a job down. A customer who insists on illegal film and refuses to sign is a job to decline, not a sale to chase.
Keep records at least three years. California's limitations period for many civil claims runs two years, and a scanned waiver and photo cost nothing to store. When a citation arrives eight months later, you want the file in one search.
Stay current. The Legislature amends the vehicle code, and you can search the current text on the California Codes: Search page. Federal glazing standards from NHTSA set the baseline that states build on, which explains why the California rule is the stricter one. See NHTSA Statutes, Regulations, Authorities & FMVSS | NHTSA for the federal side.
Run every tint job through the same three steps:
- Check registration and any exemption paperwork before writing the work order.
- Meter the existing glass and record the VLT on the work order.
- Have the customer sign the waiver, hand over a copy of the statutes, and file everything.
That sequence keeps a citation from turning into a legal problem, and it earns the kind of trust that shows up in referrals. For where that trust pays off geographically, see which markets actually suit.
Common questions
What is the legal tint limit in California?
Front side windows must pass at least 70 percent visible light transmission. Rear side windows and the back glass can be darker when the vehicle has an outside mirror on both sides. The windshield takes only a top strip or clear film that meets the standard.
Can a driver get a medical exemption for tint in California?
Yes, with a written statement from a licensed physician. The exemption does not legalize any shade the driver wants, but it lets them present the paperwork at a traffic stop. Keep a signed copy in the job file.
Does the DMV inspect tint during registration?
Not routinely. The DMV may check film during vehicle verification for out-of-state or revived registrations. Most tint enforcement runs through law enforcement citations and the court, not the DMV window.
Is a signed waiver enough to make illegal tint legal?
No. A waiver records that the customer accepted the risk, and it protects the shop in a dispute. It does not override the vehicle code, and it does not stop a citation.
