The permissible levels of emission of various gases in cars will vary according to the make and model of vehicles; different "years" and types of cars will have different criteria when tested by government agencies.
Exhaust emission tests are designed to measure carbon dioxide, as well as hydrocarbons and carbon monoxides. Each year any type of car will pass or fail an exhaust emission test, based on certain recommended numbers for that vehicle.
If a car is well maintained, it may have a better chance of passing an exhaust emission test. As you can see, there is really no hard-and-fast amount of emissions for various gases in cars - what you decide to drive will determine how inspectors rank your vehicle.
When exhaust emissions exceed the recommended level for a car's age and model, the vehicle will not pass the exam. The car or truck will need to be upgraded to reduce emissions before it can be re-tested and rated as safe; generally, owners will have a certain number of days to repair or upgrade their vehicles. When the deadline hits, they must prove to inspectors that their vehicles are running with lower emissions. The goal of testing is to protect the environment and ensure a healthy future for upcoming generations.
Choosing a newer vehicle that is designed to process fewer harmful emissions can be a great way to ensure that you pass exhaust emission tests. Certain modern cars, such as planet-friendly hybrid Prius', will use partial electric power and therefore offer significant reductions in emissions.
