Time for an
Emissions Test?

Registered vehicles are required to have an emissions test every 2 years.



Idaho Emissions Testing and Rock Chip Repair proudly serving Ada and Canyon county residents at our convenient location.

It's important to get your vehicle tested for appropriate levels of volatile hydrocarbons, carbon monoxide, and carbon monoxide plus carbon dioxide. Motorists will be sent a post card to notify them that an emission test is needed for their vehicle. Be careful not to miss the deadline.

We also do Rock Chip repair. It's best to seal a small chip as soon as possible to prevent further damage due to weather or even rough roads or bumps. This lasts for years and prevents replacement of a windshield.

Our Location

We are conveniently located directly on the SW corner of McMillan and Eagle in the Stinker Store lot.

Why Get Emissions Testing?

Air pollution in Ada and Canyon counties has exceeded health standards and federal law requires us to do emissions testing of vehicles in order to keep our air quality within those standards. Vehicle emissions are one of the largest contributors of pollution. When a vehicles emissions control equipment malfunctions, the vehicle can produce 100 times, or more, pollution than it normally does. Identifying these malfunctioning vehicles and requiring them to be repaired significantly reduces vehicle pollution.
(Testing information has been gathered from Ada County Air Quality Board.)

Maintaining Idaho’s air quality is a job where everyone can play a role. Poor air quality is unhealthy for everyone, but especially for children, senior citizens and people with respiratory conditions like asthma. With cleaner air, there are fewer trips to the emergency room and lower respiratory illness rates. It also keeps wildlife and plant life thriving.Cleaner, healthier air requires both local and regional efforts. The Air Quality Board (AQB) leads Idaho in caring for the state’s air quality by partnering with communities, business and industry, organizations and private citizens to provide the knowledge and tools necessary to create workable solutions to air quality issues.

Rock Chip Repair

Windshield rock chip repair is possible in certain cases. The best time to get a windshield chip fixed is immediately after it happens. Chips can become cracks. If the weather’s either hot or cold, that crack can grow before your eyes. Even if temperatures are mild, the chip will most likely get larger.

Unrepaired damage will eventually wreck the windshield as water permeates the layers of glass, causing condensation and decreasing visibility.

What Type of Windshield Rock Chips Can Be Repaired?
In some cases a chip isn’t even a chip. It’s just dirt from the rock. Give the spot a quick rub with a rag. If the stars align in your favor, you’ll discover the mar is only a particularly stubborn bit of dirt.

Most of the time, unfortunately, your eyes haven’t been misled. The damage is real, and you’ll need to get it taken care of. Here are the types of chips that may repairable:
Small chips: Chips 1 ¼ inches or smaller can usually be repaired. Place a quarter on the chip. If the chip and any cracks that radiate out are covered, you’re in luck. Damage that covers an area larger than a quarter may be too much to repair.
Certain shapes: What do bullseyes, flowers and stars have in common? They all describe the various shapes a rock chip can take. These types of chips can usually be filled. If the center of the chip consists of crushed glass, it may be beyond help.

What Type of Damage Can’t Be Fixed
Besides crushed glass, long cracks can’t be repaired. Old chips that were previously fixed also won’t get a second chance. Cracks that resemble spider legs poking out from the chip usually can’t be filled. If the chip and crack is at the edge of the windshield, you also might be out of luck.

How Are Windshield Rock Chips Filled?
A special resin is injected into the center of the chip. With the help of some pressure applied with a vacuum, the resin spreads and fills the cracks extending from the center of the chip. The process takes less than 20 minutes. Once it’s done your windshield is safe and ready for the road.

What Will the Fix Look Like?
The repair will be slightly noticeable, but will still be an improvement over a crack. Even if there’s a slight flaw in the glass, you will have saved the glass from further cracks that would make the windshield unusable.

Results may vary.
