will be sent no less than two notices to complete an emission test or received an
approved waiver, exemption or extension for their applicable vehicle before the
registration is subject to revocation.
1st notice will detail
what vehicle needs testing and list available testing stations in Canyon County.
Motorists will have until the end of the designated month to complete the required
2nd notice will be
sent at the end of the 30 day testing period reminding the motorist that they failed
to complete the test and if they do not complete the test within the next 35 days
from the date of the notice, their vehicle registration will be revoked by ITD.
Notices will be sent to the address on record with Idaho Department of Transportation.
In the event that the motorist fails to complete the required emissions test or
receives an approved waiver, exemption or extension within the required time – the
Idaho Department of Transportation will revoke the vehicle's registration. After
revocation, if the motorist completes a passing emissions test or receives an approved
waiver, exemption or extension, the registration will be reinstated at no additional
cost to the motorist. If the registration is revoked and expired, then the motorist
will need to complete a passing emissions test or receive an approved waiver, exemption
or extension in order to purchase a new or renew a registration from the Idaho Department
Your registration has not been revoked. Since you have received your final notice,
you still have plenty of time to have your vehicle tested. Upon receiving the final
notice you have 35 days from the date on that notice to complete an emissions test.
If you fail to pass an emissions test during that period, your registration will
be subject to revocation.
be completed at approximately 20 different testing locations listed online at www.idahoVIP.org
on the "Test Stations" link.
We also have a reciprocity agreement that allows us to accept emissions tests performed in other jurisdictions within the United States. The "Reciprocity Agreement Form" can be found at www.idahoVIP.org.This link also contains a table that lists the jurisdictions that are currently conducting emissions tests throughout the United States.
When you have your vehicle’s emissions tested in another jurisdiction, you must
fax or mail us a copy of your passing test certificate to get credit for passing
an emissions test.
This program was established based on EPA standards,
which state that a visual inspection shall be conducted on all applicable model years. The purpose of the visual inspection
is to ensure the vehicle has all the emissions control devices originally required
by the manufacturer pursuant to the requirements of the Clean Air Act and they appear
to be in good working order. To remove or render inoperative any emissions control
device or element of design installed on or in a motor vehicle or its engine in
compliance with federal regulations is prohibited and constitutes “tampering.”
is defined by the Clean Air Act of 1970 (revised in 1977) to be the
removal or rendering inoperative of any emissions control device or element of design
installed on or in a motor vehicle or its engine in compliance with federal regulations
prior to its sale and delivery to the ultimate purchaser, or for any person knowingly
to remove or render inoperative any emissions control device or element of design
after such sale and delivery to the ultimate purchaser (Clean Air Act Section 203(a)(3)(A)).
For the purposes
of the Canyon County and City of Kuna I/M vehicle emissions testing
program, vehicles that are found without emissions control devices will fail the
emissions test until the vehicle is brought back into compliance with manufacturer
emissions control device specifications. Consumers should be aware that if the emissions
control device is not working properly and is still intact on the vehicle and the
vehicle is under 8 years old and under 80,000 miles, they may qualify for a manufacturer
warranty for emissions control devices.
Waivers and extensions will not be granted for vehicles with tampering-related emissions
test failures in accordance with federal guidelines (40 CFR 51.360(a) (3)).
As long as your principal residence or domicile is located in Canyon County, you will be subject to emissions testing.
of a vehicle registered by a county assessor shall give
his principal residence or domicile address to the assessor so that the proper
county can be entered upon the registration. Failure to do so shall be
unlawful… For the purposes of vehicle registration, a person is an
actual and permanent resident of the county in which he has his principal residence or domicile. A principal residence or domicile shall not be a person's workplace, vacation, or part-time residence.” (Idaho Code §49-401B(5))
If emission testing is being conducted in the area where the student is located, an emissions test should be performed in that jurisdiction and submitted here. An emissions test from another jurisdiction will be accepted as a reciprocal test. For more information on the locations where emissions testing is currently being conducted, please see the “Reciprocity Waiver Application Form” at www.idahoVIP.org. Once the test is complete, please fax, mail, or e-mail us a copy of your passing test certificate so we can give you credit for passing an emissions test.
testing is not being conducted in the area where the student is located, he/she may qualify for an extension that lasts 6 months from the date the first notice was issued. An extension form is available
Although it is true that your registration will be revoked if you fail to have your vehicle’s emissions tested, your registration will be reinstated within 3 business days of passing an emissions test or receiving an approved waiver, extension, or exemption, without additional expense.
The following types of vehicles are exempt from emissions testing requirements according to Idaho Code §39-116B as specified in IDAPA 58.01.01.517.05.
Electric or hybrid vehicles
Motor vehicles with a model year less than 5 years old
Motor vehicles with a model year older than 1981
Classic automobiles as defined by section §49-406A, Idaho Code

County and City of Kuna vehicle emissions testing program is a basic I/M program
(as defined by 40 CFR 51.352) that regulates emissions from light-duty vehicles.
For the purposes of this program, light-duty vehicles have been defined as vehicles with a GVWR of 14,000 pounds or less.
Hardship and repair waiver forms can be found at www.idahoVIP.org on the “Forms” link. To qualify for a waiver, you must follow the instructions carefully and submit all of the required documentation and information for your situation. Repair and hardship waivers last for one year. Afterward, the vehicle must be repaired, regardless of cost, and pass an emissions test.
No. You can have your vehicle tested at any time for informational purposes.However, for a test to count towards
program compliance, the test may only be conducted up to 75 days prior to the required
testing due date.To determine the
testing due date, go to www.idahovip.org,
click on “Test Due Date”, then enter the License plate or VIN.
It is considered a violation to sell or install a used catalytic converter unless it has been properly tested and certified. The seller, installer, and owner can all be held liable for tampering if an uncertified catalytic converter is installed.
Vehicles that were manufactured in 1996 or later (and were manufactured more than five years ago) are required to have an onboard diagnostic (OBD-II) emissions test.
The federal government has mandated that 1996 and newer vehicles be equipped with an OBD-II system. The OBD-II system monitors the performance of emission control devices while the vehicle is being driven. OBD-II is mostly software with additional hardware that makes these self checks possible. OBD-II is designed to detect emission faults, especially those which could cause emissions to exceed the federal emission standards by 50 percent.
The Check Engine light will illuminate when the same emissions Diagnostic Trouble
Code has been detected more than once. This light alerts the driver that the vehicle needs to be repaired. Federal regulations require that the check engine light only be illuminated for emissions-related malfunctions.
An OBD-II emissions test is faster and more thorough than a tailpipe emissions test. It is also widely accepted, nationwide, as the standard for testing emissions of 1996 and newer vehicles. Idaho uses the OBD-II system to verify emissions compliance. The simple "plug-in" test asks the vehicle’s OBD-II system if it has it found any problems. If the check engine light is not illuminated and the OBD II system does not detect diagnostic trouble codes, the vehicle is assumed to be in emissions compliance and passes the test.
Federal law requires emissions control systems on 1995-and-newer vehicles be warranted for two
years or 24,000 miles. Many auto manufacturers provide extended warranty coverage. Federal law also stipulates that Catalytic converters on 1995-and-newer vehicles be covered for 8 years or 80,000 miles. Consult the owner’s/warranty manual to find out about your vehicle’s coverage.
The efficiency of the transmission directly correlates to how hard the engine is running. If the engine is working harder than it normally would, there is an increase in emissions because the vehicle is not operating as efficiently as designed.
Readiness monitors are programs that monitor the performance of a vehicle’s emission control devices while the vehicle is being driven. During an emissions test, the emission testing analyzer checks the status of the readiness monitors. The status of a completed readiness monitor will be ready. The status of an uncompleted readiness monitor will be
not ready. If too many readiness monitors are
not ready, your vehicle will fail an emissions test.
If any monitors
are not ready, they can mask emissions problems with the vehicle—even if there are emissions problems, they won’t be detected because the monitor is not ready to allow detection. However, some of the monitors can be difficult to set, so it is sometimes possible to test with one of the monitors
not ready, but only if:
For any test—It is not an oxygen sensor or catalyst monitor.
For a retest—
oIt is not a monitor that was
ready during the initial test, unless it is the evaporative monitor. (Depending on the weather, it can be hard to set the evaporative monitor because it has strict temperature requirements.)
It is not a monitor that caused the check
engine light to be on when the vehicle was presented for the initial test.
The monitors will be reset when a “drive cycle” is completed. In most cases, driving normally for several weeks (up to 1,000 miles) will satisfy drive cycle requirements. The specific drive cycle depends on the make and model of the vehicle, and the requirements are sometimes discussed in the owner’s manual. If this information is not available, the generic drive cycle may reset the
To have your name removed from the emissions testing requirements for a vehicle you have sold or traded, you must obtain a copy of the receipt from the Department of Motor Vehicle (DMV) or the Idaho Transportation Department (ITD) stating that a “Notice of Release of Liability” has been filed as proof that the vehicle has been sold or traded.
·Idaho Code §49-526
requires a seller to complete and submit a “Release of Liability” within 5 days of selling or trading a vehicle.
·ITD’s “Notice of Release of Liability” form can be found on ITD’s website at the following address:
