Interlock Alcohol Device: What It Is & How It Works

Drink driving is an offence that can have severe penalties as it can cause many people harm. This includes fines, licence suspensions, vehicle impoundment, imprisonment, and alcohol interlock conditions. In particular, the interlock condition aims to promote safe driving behaviour for those under the program. The minimum period can range from six months to a year, depending on the charge. This article will present information on interlock devices, how they work, and the interlock condition.

What is an Alcohol Interlock Device?

An alcohol interlock device is a type of breath alcohol testing machine installed in vehicles to prevent drivers from operating the vehicle if their BAC levels are above the set limit. These devices can be required of individuals charged with drink driving violations, such as those with repeated violations or those caught with high-range blood alcohol content. Some people also purchase breath alcohol ignition interlocks for personal safety.

There are several types of alcohol interlocks with several features. Some may have semiconductor alcohol sensors, while some have more accurate fuel cell sensors. Modern devices may also have built-in cameras to take pictures or videos during the test. This adds a layer of security to ensure the driver is the same person taking the test. Lastly, GPS is another feature the device can have.

The overall costs for an interlock device can range from $2,200 to $2,500 in a year. This includes the installation fee, maintenance cost, device rental, and removal costs upon completing the program. Some factors that can influence the price are the device type, vehicle type, and the interlock provider.

Purpose of the Interlock Device

• Interlock devices prevent drivers from operating motor vehicles if they exceed the legal limits.
• It helps reduce road safety risks and the rate of road accidents, leading to fewer injuries and fatalities from car crashes.
• They can deter individuals from drinking, especially when they have to drive afterwards. As such, they promote responsible drinking behaviours and help to break dangerous habits.
• It stops individuals with drink driving convictions from committing the same charges and harming those around them.
• They help ensure adherence to safe driving practices accurately and conveniently.
• It also serves as a monitor for law enforcement officers and court officials.

How Alcohol Interlock Devices Work

Alcohol interlock devices work similarly to a standard breathalyser. In many cases, the device has a tube or mouthpiece for the driver to blow into and provide a clean breath sample. They must blow into it until the machine receives a sufficient sample for analysis. After a few minutes, the alcohol ignition interlock device will measure the BAC level of the person.

If amounts below the set limit are found, the car will start. Otherwise, it will refuse to turn on until the driver gives an alcohol-free breath sample. If the individual continuously fails the test, they may get locked out of the vehicle. They will need to contact their alcohol interlock service agents to unlock the car.

Moreover, the alcohol interlock breathalyser device will randomly prompt the driver to conduct the test during the journey. This is to ensure they are not drinking alcoholic beverages while driving. They must pull over and quickly comply with the breath test. Otherwise, the device will sound an alarm until they do. It may also record it as a missed test.

Cut-Off Levels

The cut-off levels of the device can depend on the applicable alcohol interlock conditions. Typically, devices are sent to prevent drivers from operating the car if they exceed zero BAC. However, in some territories, they may allow a limit of up to 0.02%.

Generally, a higher BAC level indicates an increased level of impairment. Even at 0.02%, some may become overconfident and lose their sense of judgment. Hence, many consider driving with a BAC above zero as dangerous driving. To ensure safety and avoid drinking offences, people can also use personal breath analysis equipment, such as breathalysers.

Alcohol Interlock Device – Interlock Condition

The alcohol interlock programs are for drivers convicted of high-risk drink driving offences. However, not everyone with this conviction is automatically mandated to be in the interlock program. A program requirement to get an interlock licence holder is to complete several forms and submit a certificate from a medical specialist. Those with specific medical conditions may also qualify for a medical exemption for the offender program.

Alcohol interlock program participants must pay for the applicable interlock costs. This includes the costs of installation of the alcohol interlock device, maintenance, and removal upon completion. Those with financial difficulties may check if their state offers assistance for this. They may also inquire if they qualify for an interlock exemption.

The minimum program participation period can range from six months to a year. It varies depending on the specific charge. Moreover, authorities may extend the restricted driving period if the driver does not comply with the program requirements. In some scenarios, they may disqualify the individual and suspend their licence again. Therefore, it is imperative to comply with program rules.

Installation Process

To start the process, the individual must first set an installation appointment with an interlock provider. Afterwards, they must submit the ignition interlock requirements to the accredited service provider. This includes proof of identity and the details of their motor vehicle. Once accepted, they may pay the applicable interlock costs.

The technician installs the device by connecting the wiring of the interlock device to the ignition system of the motor vehicle. It is typically placed in the dashboard or the steering column. Next, they calibrate the device to the assigned limit. After installation, they will demonstrate how to use the device

Conclusion

An alcohol interlock device is a tool that prevents drivers with BAC levels exceeding the limits from starting the vehicle. It uses accurate semiconductor or fuel cell sensors to analyse breath samples and measure the BAC to determine their fitness to drive. They also serve as monitoring devices for law enforcement officers and court officials to see if the driver is complying with the rules of the interlock program. Overall, it helps ensure safety on the roads.

The minimum period of an alcohol interlock program may range from six months to a year. This is usually a requirement for individuals with repeated drink driving offences or those found with high-range blood alcohol content. However, the person must first submit requirements before they can have an interlock licence. Moreover, the participant must cover the costs of the interlock installation, maintenance, and removal. This can cost up to $2,500.
