Smog Check Exemptions
Not every vehicle in California needs a smog check. Gasoline cars from 1975 and older are fully exempt — see if yours qualifies.
TL;DR
- 1975 and older gasoline vehicles (including motorcycles and trailers) never need a smog check.
- 1997 and older diesels, electric vehicles, and all motorcycles are fully exempt.
- Gasoline cars less than 8 model years old skip the biennial inspection — you pay a smog abatement fee on your renewal instead.
- Diesels 1998 and newer do not get the 8-year break — they’re always tested.
- Exemptions are automatic — there’s no application form. DMV’s records decide based on your vehicle’s year, fuel, and weight.

Question 1 of 2
Every California smog check exemption
All exemptions below are from the official dmv.ca.gov smog-inspections page and BAR regulations. If your vehicle fits one of these, no smog inspection is required.
🚗 Gasoline vehicles: 1975 and older
The big one. Any gasoline-powered vehicle from the 1975 model year or older is permanently exempt from smog checks — no biennial test, no transfer test.
This includes motorcycles and trailers from those years. The 1975 cutoff was frozen in place by AB 2683 (2005) — California’s old 30-year rolling exemption ended there.
🛢️ Diesel vehicles: 1997 and older
Diesel-powered vehicles from the 1997 model year or older are exempt from smog checks.
Critical nuance: diesels from 1998 and newer (up to 14,000 lbs GVWR) are always tested — the 8-year and 4-year new-vehicle exemptions do not apply to diesel.
⚡ Electric vehicles
Pure battery-electric vehicles are fully exempt — no tailpipe, no test. They also don’t pay the smog abatement fee. They do still pay registration — our EV registration fee guide breaks down the full EV bill, including the $121 Road Improvement Fee.
Note: hybrids are not exempt — they’ve been subject to Smog Check since April 2015, with the same under-8-year biennial rule as gasoline cars.
🆕 Gasoline cars under 8 model years old
Gasoline-powered vehicles less than eight model years old skip the biennial smog inspection. For 2026, that covers 2019 and newer.
You pay a smog abatement fee on your registration renewal instead (the amount is shown on your renewal notice). Separately, cars 4 or fewer model years old also skip the change-of-ownership inspection — the buyer pays a smog transfer fee instead.
🏍️ Motorcycles — all years
Motorcycles are exempt from California smog checks, period — regardless of model year. The DMV lists them explicitly as included in the exemption.
If your renewal notice ever suggests otherwise for a motorcycle, check that DMV has the vehicle class recorded correctly.
🏋️ Heavy vehicles over 14,000 lbs GVWR
Diesel vehicles over 14,000 lbs gross vehicle weight and natural-gas vehicles over 14,000 lbs are exempt from the Smog Check program.
Heavy diesels fall under CARB’s separate Clean Truck Check program instead — different rules, different agency.
🔄 Cars 4 or fewer model years old — at sale
When a gasoline vehicle 4 or fewer model years old changes hands, no smog inspection is required at all — the buyer simply pays a smog transfer fee to the DMV.
This is separate from the 8-year biennial rule above. Don’t confuse the two: 4 years for transfers, 8 years for renewals.
🔧 Small and specialty engines
Also exempt under BAR regulations: engines with two cylinders or fewer, two-stroke (two-cycle) engines (rotary engines excluded), and CNG, LNG, or LPG vehicles at 14,001+ lbs GVWR.
If emissions parts are ever unavailable for your vehicle, ask BAR about a Limited Parts Exemption: (800) 622-7733.
What is the smog abatement fee?
Newer cars don’t get tested — but they don’t get off free either.
Since January 1, 2019, gasoline vehicles in their first 8 model years pay a smog abatement fee on each registration renewal instead of getting a smog inspection.
- The fee funds California air-quality programs — it’s not a penalty.
- The exact amount is shown on your registration renewal notice and varies by vehicle age — check the notice for the current figure.
- It does not exempt you from anything else: you still renew, pay all other fees, and carry insurance.
- Electric vehicles don’t pay it. Motorcycles don’t pay it.
Jay Leno’s Law (SB 1392) — collector cars 1976–1985
Signed in September 2026. A phased exemption is coming for qualifying collector vehicles.
SB 1392, signed by Governor Newsom on September 16, 2026 at Jay Leno’s garage in Burbank, creates a phased smog-check exemption for qualifying collector vehicles from model years 1976–1985.
- Rollout: phased, beginning 2028 with vehicles manufactured before 1981, advancing one model year per year through 2033.
- Qualifying rules: at least 35 model years old, not the owner’s primary transportation, and either carrying collector-car insurance or driven fewer than 1,000 miles per year.
- Check current status before relying on it — rollout dates are based on published summaries of the bill.
Background: California had a 30-year rolling exemption until AB 2683 froze it at 1975 in 2005. This law partially restores the concept for true collector cars.

Family transfers don’t need a smog certificate
Selling to a stranger requires a smog cert. Transferring within the family doesn’t.
👨👩👧 Who counts as family?
No smog certification is required for transfers between:
- Spouse or domestic partner
- Parent, child, sibling
- Grandparent or grandchild
Use REG 256 (Statement of Facts) to document the relationship on the transfer.
⚠️ The one exception
If a family member bought the car for you without first titling it in their own name, a smog inspection is required — the DMV treats it as a regular sale.
Otherwise, smog certifications are normally valid 90 days from issuance, and the seller must provide one (except for vehicles 4 or fewer model years old, where the buyer pays a transfer fee instead).
New residents & military
Two groups people ask about constantly — here are the straight answers.
🗺️ New California residents
- You must get a smog check within 20 days of establishing residency, before registering.
- Out-of-state smog certificates are not accepted — California requires its own inspection.
- The under-8-year exemption does not waive this first inspection — even a brand-new car from another state gets tested.
- A VIN inspection at the DMV is also required for first-time out-of-state registration.
🎖️ Active-duty military & veterans
No exemption. The DMV states it plainly: active-duty military members and veterans still need a smog inspection for their vehicles.
This is one of the most common misconceptions about smog exemptions — there is no military carve-out in the Smog Check program.
What “smog exempt” really means
Exempt from the inspection — not from everything else.
You still renew registration
Exemption covers only the smog inspection. You still renew your registration on time and pay every fee on the notice — including the smog abatement fee on newer vehicles.
You still need insurance & a VIN check
Insurance requirements don’t change. And out-of-state vehicles still need a VIN inspection at first California registration, exempt or not.
Smog exemption questions, answered
Straight answers, all verified against dmv.ca.gov and BAR sources.
What year is smog exempt in California?
Gasoline vehicles from the 1975 model year and older are fully exempt from smog checks. Diesel vehicles from 1997 and older are exempt. (dmv.ca.gov)
Do classic cars need smog checks in California?
Only if built 1976 or newer — “classic” looks don’t matter; the model-year cutoff controls. Jay Leno’s Law (SB 1392, signed September 2026) will phase in exemptions for qualifying 1976–1985 collector cars starting 2028 (collector insurance or under 1,000 miles/year, and not a daily driver).
Is my 1978 collector car exempt yet?
Not yet under current law (the 1975-and-older rule still applies). Under SB 1392’s phased rollout, qualifying pre-1981 collector vehicles become exempt first (reported start 2028), advancing one model year per year through 2033.
Do motorcycles need smog checks in California?
No — motorcycles are exempt from California smog checks, regardless of model year. The DMV lists them explicitly as included in the exemption.
Do electric vehicles need smog checks?
No. Pure battery-electric vehicles are fully exempt — and they don’t pay the smog abatement fee either.
My car is 5 years old — do I need a smog check?
For biennial renewal: no — gasoline vehicles less than 8 model years old skip the biennial inspection (you’ll pay a smog abatement fee on your renewal instead). For a sale or transfer: vehicles 4 model years old or less skip the transfer inspection too (the buyer pays a smog transfer fee instead).
What is the smog abatement fee?
A fee paid on your registration renewal instead of a smog inspection during the first 8 model years. It funds air-quality programs. The amount is shown on your renewal notice and varies by vehicle age — check the notice for the current figure.
Do I need a smog check to transfer a car to my son or daughter?
No — transfers between spouse, domestic partner, sibling, child, parent, grandparent, or grandchild don’t require smog certification. Exception: if the family member bought the car for you without titling it in their own name first, a smog check is required. (dmv.ca.gov)
I’m a new California resident — do I need a smog check?
Yes — within 20 days of establishing residency, before you can register. Out-of-state smog certificates don’t count, and the under-8-year exemption doesn’t waive this first inspection.
Do diesel trucks need smog checks in California?
Diesel pickups 1998 and newer (GVWR 14,000 lbs or less) need them — with no 8-year or 4-year exemption. Diesel 1997 and older, or any diesel over 14,000 lbs GVWR, is exempt from Smog Check.
I’m active-duty military — am I exempt from smog checks?
No. dmv.ca.gov states plainly that active-duty military and veterans still need smog inspections.
Does “smog exempt” mean I skip registration fees?
No. Exemption covers only the inspection. You still renew registration, pay all fees (including the smog abatement fee on newer vehicles), carry insurance, and — for out-of-state cars — complete the VIN inspection.
Is there a smog exemption form I need to file?
No single form exists — exemptions are automatic based on DMV’s vehicle records (model year, fuel, weight). For family transfers, REG 256 (Statement of Facts) documents the relationship. If emissions parts are unavailable, ask BAR about a Limited Parts Exemption: (800) 622-7733.
Do hybrid cars need smog checks?
Yes — hybrids have been subject to Smog Check since April 2015, with the same under-8-model-year biennial exemption as gasoline cars.
My county doesn’t require smog checks — am I exempt?
If your vehicle is registered in a zip code outside the Smog Check program areas, no biennial inspection is required — but the exemption is by location, and change-of-ownership and new-resident rules can still trigger an inspection. Check your renewal notice.
