Some people on this site seem to think nitrous oxide is street legal to have in your car. First off NOS (Nitrous Oxide Systems) is a brand name, not to be confused with nitrous oxide. Second off nitrous oxide is a huge safety hazard in a car that is involved in an accident, this is why you don’t see any cars come stock with it. The bottle is under high pressure, and if it explodes, it could mean death to every passenger in the car. If you get pulled over and you have nitrous tanks, you can get a ticket. If you take your car in for inspection and you have nitrous tanks, you will fail. I don’t see how you guys think this is street legal? ---

one when in a car it needs to be seperarted by wall or have a vent tube. show it in the book the code of the law and section where it shows its illegal. yes the bottle is dangerous but that is why you need a vent tube. Im pretty sure the ppl that use nitrous know that N.O.S. is a company and not the same as NAWZ from the damm movies. other states dont allow you to have the tanks but never heard of PA having that problem ---

I was pulled over by the PA State Police, speeding, my current insurance card was in the trunk. He spotted my bottle, had a few questions and I went on my way. It is street legal. The requirements are a placard for over 25lbs on board (oxidizer with green background), and a vent tube outside the vehicle compartment. Nitrous has the same requirements as propane, which many trucking companies use instead of gasoline. ---

Not really a street legality issue, but Nitrous Oxide is pretty strictly forbidden for autocrossing and road racing. ---

its been said but yes you need a hazmat placard for over 25 lbs, it may not be hooked up meaning the lines have to be disconected at the bottle but the bottle can be in the cradle, and Nitrous oxide is an oxidizer so it still needs a “fuel” and “sorce of ignition” to complete the combustion triangle. 🙂 ---

Does anyone know if a similar law applies to nitrogen tanks? They can run some pretty high PSI numbers on those tanks. I would assume normal compressed air is not really a concern as alot of utility trucks have them onboard. [Next page](https://forums.speedlife.net/t/nos-is-legal/171194.md?page=2)
