The local ordinances require all 1965 and newer vehicles registered as, or required to be registered as Ada County vehicles, to be tested. [State law requires you to specify the county where you reside as the "domicile county" during the registration process. This "domicile county" is used to determine testing requirements, not the "1A" or other county identifier on the plate.] New vehicles bought from a new car dealer are exempt from testing for the first year.

The only vehicles which are exempt from the emissions test process are new vehicles which have a Certificate of Origin (i.e., original title from the dealer) and zero emission vehicles.

Vehicles of model year 1967 or older are exempt. Older vehicles from model year 1968 ? 1995 not in compliance with the vehicle emissions law of 2005 on February 1, 2007 continue to receive the idle emissions test. However, vehicles that have antique license plates issued by the Secretary of State are exempt from emissions testing. Illinois will test vehicles registered in another state or outside the test area. These "voluntary" tests cost $20.00.

There's no reason why not. A properly built and tuned stroker should run even cleaner than the 4.0 that it was based upon.

Emissions standards for manufacturers have become stricter over the years, so most newer cars and trucks are designed to have lower emissions levels than older cars. However, vehicle maintenance, not age, is the key factor in how much a car or truck pollutes. A well-maintained older vehicle may have extremely low emissions, and a newer car may have some slight problem that causes it to emit pollutants well above the manufacturer-designed level.

Yes. All of our vehicles come with a current emission sticker or an emission voucher that guarantees the car will pass the Colorado enhanced emissions test. In addition to tail pipe gasses the enhanced emission test checks alignment, brakes, transmission and tires. A problem with any of these systems could cause a vehicle to fail the emissions test. The fact that a car has passed this test is a good indication that the vehicle is roadworthy.

Before a vehicle manufacturer can offer a new vehicle for sale, EPA requires that various laboratory emission tests be conducted on vehicles representative of the vehicles that will be sold to car buyers, to ensure that vehicle is meeting the emission standards. The tests are conducted to simulate a wide variety of actual on-road operating conditions (such as highway driving and city driving).

Answer - Vehicular Technology, Fuel Quality, Inspection & Maintenance of In-Use Vehicles and Road and Traffic Management are the major parameters, which determine emissions from Vehicles. While each one of the four factors have direct environmental implications, the vehicle and fuel systems have to be addressed as a whole and jointly optimized in order to achieve significant reduction in emissions.

Answer - A wide range of measures is being under taken to control air pollution from motor vehicles. Major measures are as under: Good quality of road surface will lead to not only reduced vehicle operation cost but also decreased pollution.

You try to figure out why it failed the test, get the problem fixed and then try to pass the test again. This may or may not be an ordeal, depending on what's wrong with your engine, how easily the problem is to diagnose and repair, and whether or not you flunk a retest.

YES! After the conversion, your vehicle should have no problem with the emissions part of the MOT test.

Gary’s Auto Repair Inc. is a Wisconsin state approved emissions repair facility. We must first diagnosis the cause of failure before it is possible to offer an accurate repair estimate. The information above is accurate to the best of our knowledge at the time of posting, however, we will not be held responsible for inaccurate information.

Massachusetts is adding a new enhanced emissions inspection test to the current safety test beginning October 1, 1999. Generally, vehicles will be tested for emissions every other year based on model year and will continue to be tested for safety annually. Motorists will be able to choose which inspection station they use as long as the station is licensed. The cost of the test is among the lowest in the nation for this type of program.

Your vehicle exceeded the exhaust limits for hydrocarbons and/or carbon monoxide, which indicates a problem with one or more of the vehicle's emission system components. Carbon monoxide is a colorless, odorless toxic gas and is a by-product of incomplete combustion. Hydrocarbons are unburned fuel vapors. When these and other pollutants are exposed to sunlight, a chemical reaction occurs that produces ground-level ozone (usually called "smog") which is harmful to our health and environment.

Emissions standards also vary from state to state, and even regions within states. Most states will require that your car meet the specifications for the year of your engine. Another reason to stick with an early engine. It is usually possible to title the car as a pre-emissions vehicle as described in our REGISTRATION faq above.

Generally, most 1996 and newer gasoline-powered passenger vehicles, light and heavy duty trucks and busses are subject to testing after they are four years old. Diesel powered vehicles, vehicles powered exclusively by electricity, and certain other vehicles are not required to test. Click here for a list of exempt vehicles.

Despite their higher fuel efficiency, diesel vehicles tend to have relatively high levels of NOx (which contribute to smog formation) and particulate matter (a lung irritant).

A hybrid directly reduces the amount of gasoline consumed, resulting in a direct reduction in the amount carbon dioxide (the main contributor to global warming) and other pollutants produced by the vehicle. A Toyota Prius, for example, will emit about 1/3 as much CO2 over its lifetime as a large conventional sedan. The Bush administration has reported that even though they are capable of running on E85, flexfuels actually run on regular gas 99% of time.

Most vehicles are required to have an emissions test at least once every other year. However, an emissions test is required anytime a vehicle undergoes a title change.

You bet! Why would you consider buying a car without first taking it for a spin around the block? After all, purchasing a Corvette or Classic from Mershon's World of Cars will be one of the most emotional and important purchase decisions of your life!

These are passenger cars, light trucks and school buses used by the National Highway Traffic Safety Administration to conduct various compliance and experimental crash tests related to motor vehicle safety. After completion of testing, they are reported to GSA for sale. These vehicles are described as “destroyed in testing”, “not repairable for highway use”, and “salvage sale only”. Buyers of these vehicles will be required to sign a Disclaimer Statement.

The Illinois EPA's vehicle emissions test program improves air quality and public health. The federal Clean Air Act Amendments of 1990 requires emissions testing programs in large, metropolitan areas which do not meet certain federal air quality standards. Although Illinois has made significant strides to clean its air since the Amendments took effect, levels of air pollution in Chicago and Metro-East St. Louis areas still exceed these standards.

Since the majority of our air pollution in Pima County comes from motor vehicle use, maintenance of your vehicles emission system is critical to improve and maintain our air quality. If your vehicle is 12 years or older and it fails the state emissions test, you may qualify for financial assistance for vehicle emission repairs through the PDEQ Voluntary Vehicle Repair and Retrofit Program.

Ans. Only trucks with a GVWR of 18,001 pounds are required to have a New Jersey Diesel Emissions test. UD 2000, 2300, 2600, & 3300's will have to be inspected annually. Contact our service Dept. if need to have this inspection performed. We are a licensed NJ Diesel Emission Inspection center. Ans. Yes, any truck with a GVWR of 10,000 pounds & up needs to have a Federal inspection done annually. All UD's will need to have this inspection done annually.

In a word, no. Outlaw Engineering has tested vehicles before and after insulator installations and passed the stringent California State emissions testing. The vehicles that were tested were California emissions vehicles, not federal, and they were inspected by a VERY picky tech inspector at a California authorized Test and Repair facility. The tech would not allow the Hotshot intake on a vehicle even though the law stated that it was acceptable.

A When a Converter does not function, no exhaust gas conversion takes place. Usually the vehicle will run fine, but it will not pass emission test standards. This may be caused solely by a worn or damaged converter. But, it is difficult to diagnose because it involves other emission system components, as well. The most common cause of this problem is lead contamination within the converter. Use of leaded fuel is usually the source of the contamination.

The locations and wait time hotline telephone numbers are included in the vehicle emissions test notices. You can also call (847)758-3400 from 8:30 a.m. ? 5:00 p.m. Monday through Friday, or click here to see the list of locations.
