Registration

The Assessor acts as a vendor for the Idaho State Transportation Department and provides a more convenient location for Canyon County residents to handle vehicle registrations.  This local auto license office tends to be very busy around the beginning and end of each month.  To avoid long lines, renew your registration online external.  More information on vehicle registration, fees and requirements can be found at itd.idaho.gov/dmv external

Identification Requirements

Effective July 1, 2009, legal identification is required to title and register vehicles per 49-401B external.  Please be prepared to provide your Idaho driver license or identification card, or your social security number, as well as the full legal name and physical address for all owners listed on the vehicle.  In the case of a business, the business name and EIN will be required.  View the Personal Information Matrix pdf for a full list of requirements.  By bringing this information to the motor vehicle office, you will be prepared and your transactions can be processed more quickly and easily.

Identification is required for online renewal as well.  Simply type your Idaho driver license or identification card number,  social security number,  or EIN and the record will automatically validate the information.  In the event that your identification can not be validated, it will be necessary to complete the transaction in person.

Why is this required?

The Idaho Transportation Department (ITD) Division of Motor Vehicles (DMV) is working towards a “One Person-One Record” system where all of a person’s (or business entity’s)title, registration and driver records will be associated with that person (or business) in one master record.  This system will help DMV comply with a state law that will require identification of all of a person’s registrations.

How does this benefit me?

More Convenience:When DMV’s “One Person-One Record” system is operational and you move to an new address, you will only have to report the address change one time to update all of your driver and vehicle records. (Remember – you are required by law to notify the DMV within 30 days of changing your address.)  The current system requires you to update each record separately.  If you forget to update a record, you may not receive your renewal notice.

Less Stress or Confusion: When legal or administrative action is taken against someone with the same or similar name as yours, it is less likely you will be contacted with bad news by mistake.

Which address should I provide if I have several?

Provide the address that you consider your home – the place that you plan to return and remain.  Do not provide your workplace, vacation, or part time residence address.

If I am just renewing a registration, do I need to comply with all the name, number and address requirements?

Yes, when renewing an existing registration please provide your identification along with your physical address.

What if I have a grantor trust, a single member LLC, or a sole proprietorship that does not have an EIN?

After we have received and recorded documentation of your business status or trust, the system will generate a customer number for that entity.  This number should be kept for use in future title and registration transactions.

Emissions Information:

 In April 2008, the Idaho Legislature enacted and the governor signed into law Idaho Code §39-116B external, entitled the Vehicle Inspection and Maintenance Program, laying the groundwork for requiring vehicle emissions testing in areas of the state where air quality is compromised and motor vehicle emissions constitute one of the top two contributing sources to the pollution. The Treasure Valley airshed meets the criteria specified in the law, as data show that vehicle emissions constitute one of the top two emission sources contributing to ozone concentrations in the valley.

A completed emissions test will cost  $11.00.  Vehicles need to be emission inspected every other year.  Motorists will receive a notice in the mail when it is time to have their vehicle emissions inspected.

How and Where

The Canyon County program is managed by Applus Technology.

Emissions testing is available at more than 20 conveniently located businesses throughout Canyon County and Kuna. For specific testing locations, visit www.idahovip.org external.  Tests performed outside of Canyon County are also accepted. Applus and the Ada County’s Air Quality Board exchange test results on a daily basis.

Motorists may have an opportunity to request an extension or exemption from the emission inspections requirements according to the program rules. Required forms can be found at www.idahovip.org external.

Notification of Emissions Test and Deadline

There is no need to obtain an inspection before the notice is received.

Motorists are sent two notifications about their requirement to test. Notices are sent to the address on file with the Idaho Transportation Department (ITD). To ensure notices are received, motorists should make sure their address is up to date with the DMV.

The first notice will detail which vehicle needs testing and options to complete the test. Motorists will have until the end of the designated month to complete the test.

If necessary, the second notice will be sent at the end of the 30-day testing period reminding the motorist that he or she failed to complete the test and if the test is not completed within 35 days from the date of the notice, vehicle registration will be subject to revocation by ITD.  We do not want to see this happen to any motorist, so please ensure you test your vehicle.

Re-Registering a Vehicle that has had the Registration Revoked

If a motorist fails to complete the test within the allotted time and fails to receive an approved waiver, exemption, or extension, ITD will revoke the vehicle’s registration.

After revocation, if the motorist completes a passing emissions test or receives an approved waiver, exemption, or extension within that testing cycle, the registration will be reinstated automatically at no additional cost to the motorist.

If the registration is revoked and expired, the motorist must complete a passing emissions test or receive an approved waiver, exemption, or extension in order to purchase a new or renew a registration.

About the Test

Two types of testing methods are used to test gasoline-powered vehicles covered under the program. The type of test required is determined by the age of the vehicle.

Two-Speed Idle (TSI): Samples a vehicle’s exhaust for appropriate levels of volatile hydrocarbons, carbon monoxide, and carbon monoxide plus carbon dioxide.

On-Board Diagnostic (OBD): Uses an analyzer connected to the vehicle’s powertrain control module to look for broken or malfunctioning emission control components.

Diesel vehicles covered under the program are tested by the OBD method or a snap acceleration test using a smoke meter at the end of the exhaust pipe.

A visual inspection of the emission control components is conducted on all vehicles inspected.

When a Vehicle Fails the Emissions Test

Vehicles not passing the inspection will receive a vehicle inspection report with the reasons the vehicle failed. Motorists are free to select a qualified repair technician or repair the vehicles themselves. See Possible Causes for Emission Test Failurebelow for more information.

After appropriate repairs are made, a motorist is allowed one free retest if completed within 30 days of the previous test and at the same station. Vehicles subject to emissions inspection must pass the test before the deadline indicated in the official notice.  Not passing the test by the deadline will result in the vehicle’s registration being revoked.

When a vehicle fails, appropriate repairs should be completed and the vehicle retest.  If the vehicle does not pass the retest, a repair waiver may be granted if a minimum of $200 has been spent toward failure-related repairs.  Repairs for certain vehicles may be under warranty. Visit www.idahovip.org external for waiver forms.

Motorists who want to dispute their test results may be able to obtain a free diagnostic and confirmation testing from Applus Technology. This free service will be offered by appointment only.  Please see Applus’ contact information earlier on this web page.  Applus will not repair a vehicle.

Hardship Waiver

If a vehicle fails the test, a hardship waiver may be granted if the owner is not financially able to make the necessary repairs to bring the vehicle into compliance with emissions standards. Eligibility will be determined by comparing income to the current published poverty threshold as defined by the US Department of Health and Human Services external and evaluating any additional extenuating circumstances.  Visit www.idahovip.org external for waiver forms. The motorist will also be asked to provide the failed test report.

Proof of hardship is documented by the last 2 years of household federal tax returns or, if no tax returns are available, all household bills and paystubs for the past 2 months.

Other documentation that may identify extenuating circumstances might include medical bills not covered by insurance, loss of unemployment benefits, etc.

Vehicles Requiring Emissions Testing

  • Model year 1981–1995 gas-powered vehicles, using the TSI method
  • Model year 1996 and newer gas-powered vehicles more than 5 years old, using the OBD method
  • Model year 1981–1997 diesel-powered vehicles, using the snap acceleration method
  • Model year 1997–2007 diesel-powered vehicles, method dependent upon vehicle configuration at time of manufacture
  • Model year 2008 and newer diesel-powered vehicles more than 5 years old, using the OBD method

Vehicles Exempt from Testing

  • Electric or hybrid motor 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 Idaho Code
  • Motor vehicles with a maximum vehicle gross weight of less than 1,500 pounds
  • Motor vehicles registered as motor homes as defined by Idaho Code
  • Motorized farm equipment
  • Registered motor vehicles engaged solely in the business of agriculture
  • Visit www.idahovip.org external for exemption and waiver forms.

Vehicles with model year 1996 and newer with On-Board Diagnostics (OBD) will report malfunctions of specific emissions control components. Older vehicles tested with exhaust gas analysis will fail inspection if pollutants from the tailpipe are too high. The table below shows possible causes of excessive tailpipe emissions.

High Carbon Monoxide Readings High Hydrocarbon Readings
Incorrect air/fuel mixture Defective points/electronic ignition
Dirty air cleaner, choke or carb/fuel injection Open plug wire or fouled spark plug
Carburetor float level improperly adjusted Vacuum leak
Inoperative air pump Incorrect air/fuel mixture
Diluted lubricating oil Inoperative air pump
Soaked fuel evaporative canister Incorrect ignition timing

Emission Components and Their Functions

Exhaust Gas Recirculation (EGR) – Recirculates exhaust gases into intake manifold and is controlled by vacuum pressure.

Spark Controls (SPK) – Ensures that air/fuel mixture is ignited at the best possible moment to provide optimum efficiency, power and cleaner emissions.

Positive Crankcase Ventilation (PCV) – Controls the flow of crankcase fumes into the intake manifold while preventing gases and flames from traveling in the opposite direction.

Thermostatic Air Cleaner (ACL) – Supplies warm air to air intake during cold engine operation.  This system is only active during cold engine warm-up only.

Fuel Evaporative System (EVAP) – Allows for proper fuel system ventilation while preventing fuel vapors from reaching the atmosphere.  Catches and stores vapors until engine is restarted.  Vapors are then removed from storage and burned.

Catalytic Converters (OC) (TWC)- Removes/reduces nitrogen oxides, carbon monoxide, and hydrocarbon emissions as gases pass through it.

Air Injection Systems (AIS) – Draws filtered air in through the intake port and pushes air out the exhaust port.

Oxygen Sensor (O2s) – Monitors the oxygen content of exhaust gases.  It produces a voltage signal which is proportional to exhaust gas oxygen compared to outside oxygen.

    Low voltage signal = lean mixture

    High voltage signal = rich mixture

Computerized Engine Controls (CEC) – Monitors and controls a variety of engine/vehicle functions.  CEC system is primarily an emission control system designed to maintain a 14.7:1 air/fuel ratio under most operating conditions.

The following information has been adapted from the United States Environmental Protection Agency (EPA) guidelines. An EPA fact sheet with additional details can be found at www.epa.gov external.

Federally required emissions control warranties are designed to protect vehicle owners from the cost of repairs for certain emissions-related failures that result from manufacturer defects in materials and workmanship or that cause vehicles to exceed federal emissions standards. Two federal emissions control warranties are described below: performance warranties and design and defect warranties.

Performance Warranty

The performance warranty covers repairs that are required during the first 2 years or 24,000 miles of vehicle use (whichever occurs first) because the vehicle failed an emissions test. Specified major emissions control components are covered for the first 8 years or 80,000 miles (whichever occurs first). As the Idaho Inspection and Maintenance (I/M) Program meets federal guidelines, motorists are eligible for this warranty protection provided that all the following are true:

  • Their car or light-duty truck fails an approved emissions test.
  • Their vehicle is less than 2 years old and has less than 24,000 miles (up to 8 years / 80,000 miles for certain components).
  • Their state or local government requires that they repair the vehicle.
  • The test failure does not result from misuse of the vehicle or a failure to follow the manufacturer’s written maintenance instructions.
  • They present the vehicle to a warranty-authorized manufacturer representative, along with evidence of the emissions test failure, during the warranty period.

If the above are true, during the first 2 years / 24,000 miles (whichever occurs first), the performance warranty covers any repair or adjustment that is necessary to make the vehicle pass an approved, locally required emissions test.

Design and Defect Warranty

The design and defect warranty provides additional protection to many vehicle owners who may not qualify for performance warranty coverage. Motorists should check their owner’s manual or warranty booklet to see if they qualify for design and defect coverage. Some manufacturers now provide extended coverage for engine components under their regular vehicle warranties.

According to federal law, an emissions control, emissions-related part, or a specified major emissions control component that fails because of a defect in materials or workmanship must be repaired or replaced by the vehicle manufacturer free of charge as long as the vehicle has not exceeded the warranty time or mileage limitations for that failed part.

The owner’s manual or warranty booklet provides the motorist with guidance on the procedures for obtaining warranty coverage.
