It is largely accepted that the first true automobile was introduced in Germany by Karl Benz in 1885, although there is some controversy over the subject. Since the introduction of self-propelled motor vehicles the world has become a much smaller place and people have enjoyed the convenience and luxury provided by owning an automobile. New models have become faster, larger, louder, and smoother with each passing year. There is quite literally a perfect vehicle to match every personality type on the planet.
Not everything about the automobile is pleasant or beneficial. The number of accidents caused by distracted driving rise every year and people do not always use the caution that would prevent senseless accidents from occurring on crowded or slippery roadways. Despite the increased number of standard safety features on every vehicle such as airbags, seat belts, and anti-lock brakes, there is an increasing number of deaths caused each year by auto accidents.
Every state requires motor vehicles registered in their territory to be inspected. The car inspection process will vary by location and may include a mechanical safety check as well as a cursory review for general road safety conditions. Some states require only one car inspection upon registration or transfer of title while other states make these safety inspections an annual or semi-annual requirement.
Manual, automatic, and diesel engines all emit a small amount of vapor or smoke into the atmosphere during use. Generally, these emissions are relatively small compared to other pollutants produced by industrial waste and larger combustible engines used in large construction project. Even though this standard emission is a common and acceptable side effect of operating a motor vehicle, many states have begun a mandatory vehicle inspection to determine the level of emissions coming from a single vehicle. These tests are typically conducted every one or two years and help owners learn about the overall condition of their car.
Because excess vehicle emissions are typically caused by a defect or repairable maintenance item in a car that can be easily addressed, lawmakers have decided that a vehicle inspection is the best way to uncover these invisible problems. An automobile will pass the car inspection if there are no inappropriate or potentially harmful emissions being added to the environment through the exhaust system of a vehicle.
