California, Emissions and Prop 65

Here is the thing our competitors will not explain to you. Go shopping for a youth ATV and you will see the same line on site after site: "for sale in domestic US states, excluding California." Nobody ever says why. So you are left wondering whether the machine is junk, whether the seller is shady, or whether California just hates fun.

None of those. And here is the part that will surprise you: a lot of these machines are perfectly legal in California. The sellers who blanket-refuse the state are mostly doing it because checking is work.

Why California is different

California runs its own emissions program through the California Air Resources Board, which everybody calls CARB. It has done this since before the EPA existed, and federal law lets California keep a stricter standard. Off-highway recreational vehicles, which is the legal bucket ATVs, dirt bikes, go-karts and side by sides fall into, have to be certified by CARB before they can be registered for normal recreational riding in the state.

A model that is certified gets what riders call a green sticker. Green sticker machines can be ridden in public off-highway riding areas, all year, no restrictions.

A model that is not certified used to get a red sticker, which limited riding to certain seasons in certain parks. California has ended the red sticker program, and non-compliant machines from model year 2022 and newer now get a tan sticker instead. A tan sticker means closed course competition only. Not eligible for recreational riding in public areas. That is a very different machine than the one you thought you were buying, and it is the outcome you are trying to avoid.

Certification is per engine family, not per brand

This is the piece everybody gets wrong, including a lot of retailers.

CARB does not certify a brand. It issues an executive order covering a specific engine family, for a specific model year. So a manufacturer can have several engine families certified and others not, all at the same time, all under the same badge on the tank.

Here is the good news on our lineup. Coolster, through Maxtrade LLC, holds current CARB executive orders covering four engine families, spanning 72cc, 107cc, 120cc, 125cc, 149.6cc and 168.9cc. That covers most of what we sell. Which means a lot of these machines are green sticker eligible, and the blanket refusal you see on other Coolster sites is a choice they made, not a law.

What we do instead

  • If you are in California, call or email us before you order. Tell us the model you want. We will look up the exact model and model year against CARB's published executive orders and tell you what we find.
  • If it is certified, we will tell you and we will sell it to you. Our competitors will not, and that is their choice, not a law.
  • If it is not certified, we will tell you that too, and we will not sell it to you. We are not going to take your money for a machine that can only legally be ridden on a closed course when you were planning on the state riding area an hour from your house.
  • One we already know about: the ATV-3250S runs a 196.9cc engine, which does not map to any Maxtrade executive order we could find. Assume that one is not California eligible until we confirm otherwise.

How to check for yourself, on any machine, from any seller

CARB publishes public executive order lists for emissions-compliant off-highway recreational vehicles, organized by model year and manufacturer. Look up the manufacturer and confirm the displacement of the machine you want falls inside a listed engine family for that model year.

If it is not on the compliant list, it is not green sticker eligible, no matter what the listing says. That is a five minute check that will save some family a very expensive mistake this year. Do it even if you are buying from a competitor. Especially then.

Proposition 65

California also has Proposition 65, which requires a warning when a product can expose you to certain listed chemicals. Gasoline engines land in that bucket, because engine exhaust and carbon monoxide are both on the list, and so is the lead in a standard battery terminal.

This is a disclosure law, not a safety rating. A Prop 65 warning on a gas powered machine does not mean it is more dangerous than any other gas powered machine. Every internal combustion engine sold in California carries some version of it, including the one in your truck.

The practical takeaway is the one you already knew: never run a gas engine in a closed garage or shed. Carbon monoxide is the real risk here, it is odorless, and it is genuinely deadly. Doors open, every time, no exceptions, even for a two minute warm up.

Emissions hardware, and please leave it alone

Every machine we sell comes from the factory with the emissions equipment it is supposed to have, including a spark arrestor where one is fitted. Two reasons not to remove any of it:

  • Tampering with emissions equipment is a federal violation, not just a California one.
  • A spark arrestor is required on most public land, including nearly all national forest, and it is the piece of hardware that keeps a hot exhaust from starting a wildfire. Rangers do check.

Leave it on. Ride where you want to ride. It is not costing you anything you would notice.

One honest disclaimer

We sell machines, we are not attorneys and we are not your compliance department. Emissions rules and registration rules change, and they vary by state and sometimes by county. Everything above is our plain English read of how it works as of today, and it is meant to help you ask better questions, not to be legal advice. For anything binding, check with CARB, your state DMV or your local land management agency.
