Quick read: Three different distinctions get confused with each other — STAR vs. regular, test-only vs. test-and-repair, and price. They are independent. STAR is a certification level the DMV can require. Test-only vs. test-and-repair is what the station is licensed to do. And there is no state-mandated price difference between any of them. Reading your notice correctly is worth a wasted trip.

First: does your notice say STAR?

If it does, that is not a suggestion. A regular station's certificate will be rejected by the DMV for a STAR-directed vehicle. You would pay for an inspection that does not count.

Vehicles get directed to STAR for two reasons. Most are flagged by BAR's high-emitter profile — an algorithm weighing make, model, year, mileage and inspection history. The rest are a roughly 2% random selection in enhanced program areas. Coastal North County is an enhanced area, so the random draw applies here. Neither reason means anything is wrong with your car.

The notice states it explicitly, and stations display the STAR seal. If you're unsure, BAR's own station locator at search.dca.ca.gov shows every licensed station's type and current status.

Second: STAR comes in two kinds

This is the part almost nobody knows. STAR certification is not the same thing as test-only. A station can be STAR test-only or STAR test-and-repair — both are STAR, both satisfy a STAR-directed notice, and both are independently audited by the state against stricter equipment and inspector-certification standards.

• Test-only — performs the inspection, cannot perform paid repairs. Structurally it cannot upsell you a repair, because it isn't licensed to sell one. If you fail, it sends you elsewhere.
• Test-and-repair — licensed to both inspect and fix emissions failures. A STAR test-and-repair station also handles DMV-directed retests and gross polluters.

Encinitas STAR Smog & Auto Repair at 310 Encinitas Blvd is a STAR-certified test-and-repair station. Practically, that means a STAR-directed vehicle can be inspected there, and if it fails, the repair and the retest can happen without relocating the car to a second shop.

Which one should you actually pick?

It depends entirely on one question: do you expect to fail?

• Confident it will pass — either is fine. Test-only is the more impartial structure and is what many DMV-directed customers prefer for exactly that reason.
• Check engine light on, recent emissions work, a car that failed last cycle, or an older high-mileage vehicle — start at a test-and-repair station. A failure at a test-only station means towing or driving the car to a repair shop, then back again for the retest. That is two trips and, often, two inspection fees.

There is no honesty penalty either way. Both types must meet the same BAR calibration and certification standards, and a test-and-repair station's inspection is held to the same rules as a test-only station's.

Third: price is not set by any of this

BAR does not set a price difference between STAR and regular stations, or between test-only and test-and-repair. Each station sets and posts its own price; BAR's requirement is that the price is posted, not what it is. Anyone who tells you STAR costs more "because it's STAR" is describing their own pricing, not a state rule.

What it costs. There are two separate numbers here, and stations do not always separate them clearly. The inspection fee is set by the station and posted on-site — BAR requires the price to be posted, not what it is — and it varies by vehicle: SUVs, trucks, vans and diesels are priced differently from a standard passenger car, and 1999-and-older vehicles cost more because they need the slower tailpipe protocol instead of an OBD-II scan. The $8.25 state certificate fee is fixed by California and charged only when the vehicle passes — a failed inspection never produces a certificate.

The Encinitas logistics nobody mentions

Encinitas has no DMV field office of its own. The nearest is the DMV Oceanside Field Office, which is worth knowing if you have left a renewal late and are planning to handle it in person. You do not need to visit the DMV for the smog check itself — a passing result is transmitted electronically by the station.

How to read your notice in thirty seconds

1. Does it say STAR? If yes, a regular station's certificate won't be accepted. If no, any licensed station works.
2. Does it say gross polluter or DMV-directed? STAR is required, and the vehicle must be repaired before re-inspection.
3. Do you expect to fail? If yes, pick test-and-repair and save a trip.
4. Check the posted price — it's per-station, so compare the actual number, not the station type.

What happens if you fail — and why station type matters most here

Every inspection produces a Vehicle Inspection Report naming the exact cause of the failure. Read it before authorising anything: the most expensive mistake after a failed smog check is paying for a repair that was never the problem.

The most common causes, in order: a check engine light (an automatic failure regardless of how the car drives), a failed oxygen sensor, catalytic converter degradation, and readiness monitors not set.

That last one is not a fault at all. "OBD not ready" means the car's computer hasn't finished its own self-checks since it was last reset — usually because the battery was disconnected or codes were cleared before the test. There is no repair to buy. The fix is roughly 100–150 miles of varied driving: cold starts, surface streets, sustained freeway speed. If a shop offers to clear the light before a test, that causes this failure rather than avoiding it.

This is where the station-type decision pays off or costs you. At a test-only station, a failure means taking the car to a separate repair shop and then returning for the retest — two trips, and often two inspection fees. At a test-and-repair station like the Encinitas Blvd location, the diagnosis, the repair and the retest can happen without relocating the vehicle. On a car you suspected might fail, that is the whole argument.

What the retest costs

California allows unlimited retests. An inspection fee applies each time the vehicle is tested, but the $8.25 state certificate fee is charged only on a pass — a failed test never generates a certificate, and nothing reaches the DMV until you pass. Free or reduced-price retests are a shop policy, not a state rule, and typically apply only at the station that performed the original inspection. Ask before the first test.

If the repair bill is the real problem, the Consumer Assistance Program offers up to $1,450 toward emissions repairs on 1996-and-newer vehicles, plus a vehicle-retirement option of roughly $1,350–$2,000 for taking an older polluting vehicle off the road. Eligibility runs through income limits or a DMV-directed inspection, and you must apply through BAR before the repairs are done — approval is not retroactive. See the CAP program, step by step.

Either way, a failure does not ground the car. You can drive until the registration expires; you just cannot renew it without a passing certificate on file.

How long it takes

A standard OBD-II inspection on a 2000-or-newer vehicle is a short job — typically under 30 minutes. Vehicles from 1999 and older take materially longer, because they predate the OBD-II port and require a tailpipe gas analysis plus a visual inspection of emission components rather than a scan. That difference is why the posted price for pre-2000 vehicles is higher; it is labour, not a surcharge.
