How is Jay Leno's Tank Car (Youtube) street-legal in California?

California has some of the most-strict laws regarding what kinds of car modifications you can make to a production car and still be street legal. Basically, if it's not on a list of approved mods, it's not legal.

Leno's car is a custom chassis mated with a 12 cylinder tank engine, and he drives it on public streets in California. How did he manage to get this CA legal with respect to the California Air Resources Board (CARB)?

I can just make out that it has a special CA license plate (42 seconds in). What kind of plate is it?

The Tank Car's plate is a California "Historical Vehicle" plate, which many be issued upon request for vehicles that are at least 25 years old built after 1922 [PDF of plate application with requirements]. The plate restricts the vehicles to be only driven in historical exhibition, parades or historic club activities. So, it's not really street-legal in that Leno can drive it when/where ever he wants.

I think you've hit part of it. It's not a production car.

I don't know thing one about California law, but I know that a lot of states have a weight above which you're no longer required to meet certain requirements. I don't know what that thing weights, but I'm willing to bet it's in the neighborhood of three tons.

Also, the states I'm most familiar with list pollutant requirements as a percent of total emissions not as a quantity. So your Cooper Mini might be producing an unacceptable percentage of unburned hydrocarbons and still be putting out half as much as a larger vehicle.

The DMV has as special process for Custom Built Cars which includes a CHP vehicle verification and a SMOG cert. Basically the CHP verifies the road worthiness and the SMOG cert handles emissions.

Single vehicle and/or low production volume regulations exist for certain types of car and don't require meeting the same standards as production cars in many countries, including the US. There are a massive number of loopholes to get something like that through and most countries have a way of defining how one-offs and kit cars can be assessed. It would be extremely unusual if California didn't have an equivalent system.

Regarding the emissions, Calif exempts cars built in 1975 or older from emission testing. Given that DMV issued a historical plate for it which requires the car to be at least 25 years old, it's likely grandfathered in for the smog, too.

Added bonus fenders are not required.

More than likely it's registered as a Specially Constructed Vehicle (SPCNS). The key here is that the chassis is custom and not based on any production car (something with a VIN). California SPCNS regulations are actually very liberal, and if you're particularly zealous and do your homework, you can even get a smog exemption.

If instead Jay had taken an actual old production vehicle and swapped the engine, then it would not fall under SPCNS regulations.

While the car was put together relatively recently you'd probably find if you pulled the registration that the car is officially a '48 ford or something. That gives you a historic plate on a new rod and neatly side steps requirements for stuff like emissions, fenders, lights and other assorted equipment.

About 2 minutes into this video he swears it's totally street legal.
