What is the Intoxalock®?

The Intoxalock® is a state-of-the-art, alcohol specific, breath alcohol ignition interlock device (BAIID). The device is designed to prevent an individual from operating a motor vehicle while under the influence of alcohol. <Top

How does the Intoxalock® work?

The unit is connected directly to the electrical system of the vehicle. If the breath alcohol of the driver is above a preset limit, the vehicle will not start. <Top

How do I operate the Intoxalock®?

Before a driver starts their vehicle, they will be required to give a breath sample by blowing into the mouthpiece of the unit.

The Intoxalock® will determine the amount of alcohol in the driver's system (BAC). As long as the driver's alcohol content is below the state's legal limit, the vehicle will start. If the unit registers an alcohol level above the preset limit, the vehicle will not start. If this happens, the driver will be allowed to submit another breath sample in a short period of time.

Additionally, states require that random checks be performed on drivers.

This is accomplished by utilizing a feature called the "rolling retest." The unit will randomly generate a retest time as you are driving down the road.

At the point of retest, the driver will be required to submit another breath sample to determine whether or not they have started drinking after they have started the vehicle. If the driver's breath alcohol goes above the preset limit, the vehicle's horn will start honking. This failure is designed to gain the attention of many people including police officers.

Please be aware that under no circumstances does the Intoxalock® have the ability to shut a vehicle off while it is being operated. Pulling off the road and turning off the vehicle will disengage the horn. The driver is then safe, but may be unable to restart the vehicle until they deliver a clean breath sample. <Top

How much does it cost to have the Intoxalock®?

This is the question that people ask most. There are pricing differences among various states. Please call us directly to find out the fees associated with your state's program. We can tell you that a DWI/DUI is expensive. The additional cost of having an interlock installed (approximately $2/day average) is a small price to pay to maintain legal driving privileges, keep your job and most importantly, eliminate the risk of obtaining future drunk driving offenses. <Top

What if your unit malfunctions?

Should the unit appear to be experiencing problems, simply contact our customer service team at 877-777-5020. Our staff is highly trained to diagnose potential problems and can often resolve the problem over the telephone and have you back on the road in short order. In the rare instance when a unit does malfunction, we will take every step necessary to minimize any inconvience to you including replacing the malfunctioning unit with a replacement unit that day or the next day depending on your location. <Top

Can I still drink?

In most cases, the answer is yes. The Intoxalock® will record and log every breath sample where alcohol was present. Because of this, alcohol should be consumed in very limited amounts while operating a vehicle equipped with the Intoxalock®. Our suggestion is that if you are going to drink, please walk, take a cab or let someone else drive. <Top

Where can I get the Intoxalock® installed?

CST has contracted with Circuit City Inc. electronic stores across the country to provide installation and service at over 500 Circuit City Road Shops. Additionally, CST contracts with new auto franchise dealers who employ trained installation technicians. Please contact us for information about the nearest installation center . <Top

How do I let the state know that I have an interlock installed?

When you have your Intoxalock® installed, you will receive an "installation certificate" to present to your state's regulatory agency. This verifies that the device has been properly installed. <Top

Will other people be able to drive the vehicle?

The answer is yes. We must warn you though that there is no way of verifying that you were not the person driving the vehicle. This means that you become responsible for everything that the unit records. If another person was driving the car you are still responsible for any consequences that arise if the person was drinking. <Top

How noticeable is the Intoxalock®?

The handheld unit that the driver blows into is 5 inches long, 1 inch in depth and 3 inches wide. <Top

How long does it take to get the Intoxalock® installed?

We generally require a minimum of three to seven days notice to have a unit installed into a vehicle. This time is necessary to process all of the paperwork and to ship the device to the installation center. When you arrive at the installation center, you will need to allow one to three hours for the device to be installed. <Top
