What makes a car 'street legal' and 'street illegal'?

Emissions, certain lights and safety equipment removed, certain tyres being equipped. Basically, if you can register the car legally (it will pass all the tests that other normal cars are given) then it is 'street legal'. If it does not...then it is street illegal.
 
Whatever the Department Of Transportation says needs to be on a car, is what your car needs to be legal.

If you don't meet all the criteria set forth by your states DOT, then your car is illegal.

Check with your states DOT for laws regarding what is legal or illegal in your state.

I just noticed that your living in Canada, so disregard this post. The only thing that would make a Canadian car illegal is if it only had 3 wheels, and then only maybe. J/K :D

I'm sure you have something like the DOT in Canada, check it out. :)
 
Like they said its all basically emissions. As for my car I dont have an catylitic converters, and my brothers GSX vents its blow-off as well as an external wastegate, all that is illegal.

the venting of you brothers BOV is not what makes that illegal, the result of the BOV venting to atmosphere causes unburnt fuel (due to the lack of oxygen that the engine management system thinks it has) to be expelled out the exhaust is what make it illegal

I've been under the impression that you can't have "open wheels". The tops must be covered by the body of the car.

Unless you're driving a Prowler, or maybe some old fashioned hot rod.

Like so:

It would be interesting to find out how excatly they determine what constitiutes as covering the wheels with the body, i.e. do the fenders on someting like the prowler need to be a certain size, etc.

Each state (and the federal government) has strict rules about passenger cars' roadworthiness, but each state also makes loads and loads of exemptions for collector vehicles. Street rods are even worse - just about anything will do.
 
Nitrous oxide does not make a car illegal. Posession of it opened is illegal unless you have a doctor's permit for it (like you are a dentist). But N20 actually burns more fuel, therefore lowering the amount of pullutants that go into the air.
 
nitrous does not burn more fuel. it breaks down releasing more oxygen and allowing a suitable larger fuel charge to extract more power from the same amount of "air."

all nitrous does is release more air into the cylinder. this is why you require more fuel for nitrous use.

Umm... Does that make sense to anyone?

I think what he means is that with the addition of N2O in the fuel mixture, more fuel molecules are burned as opposed to a engine without N2O where many fuel molecules are not burned and spent in the exhaust, hence using N20, it creates a cleaner exhaust.

I think? :odd:
 
But that would probably result in a lower hydrocarbon emission and a significantly higher CO/CO2 emission, right? And since both HC/CO emissions are measured in our yearly MoT tests, you'd probably fail...

Hell if I know, I was purely speculating when trying to decipher for you what Shob had said.

You asked man. :D

And why would someone be sprayin NO2 while getting there emissions test done anyways?
 
you burn more fuel with N20 because if you dont you will cause your engine to run lean, causing pinging, the temperatures to go up and resulting in a busted engine.
how does burning more fuel equate to less emissions? the only way that can happen is if the introduction of nitrous results in a more complete burn of the fuel air mixture or the nitrogen combines with other particulates to create less harmful emissions.

That's a good question. Still, if they're enough of a dick to HAVE nitrous in the first place... :D

Oh whatever, you haven't even got to pass emissions tests you rural freak.

Difference is that ShobThaBob is a US member, and in the US, we don't

- care about carbon dioxide emissions.
- base an entire system of complicated taxing on carbon dioxide emissions.
- have MoT's (we aren't freaks).

:D
