Understanding how much an interlock device costs is the first step for anyone facing a DUI charge or required to install one for work. These devices, known as ignition interlock devices or IIDs, act as a critical safeguard against drunk driving by preventing a vehicle from starting if alcohol is detected on the driver's breath. The price is not a single flat rate but a combination of installation fees, monthly rental charges, and potential additional costs for maintenance or calibration.
Breaking Down the Initial Price Tag
The upfront cost to acquire the device is typically bundled with the installation fee, rather than sold as a separate purchase. When looking at how much an interlock device setup costs initially, you are generally paying for the hardware, the professional installation at a certified shop, and the first month of service. This initial package usually ranges from $100 to $150 for the device installation itself, though the device rental is often a separate recurring charge. The total startup cost often lands between $150 and $200, depending on the provider and the specific requirements of the court or employer.
Monthly Rental and Service Fees
The most significant ongoing expense related to an IID is the monthly rental fee. This fee covers the use of the device, the cellular connection for reporting, and customer support. On average, drivers can expect to pay between $60 and $90 per month for the rental. This cost can vary based on the state, the specific monitoring requirements, or if the device includes GPS monitoring or camera features. Budgeting for this monthly expense is essential, as the rental period typically lasts for a minimum of six months to a year, as mandated by the court or DMV order.
Factors That Influence the Cost
Not all interlock devices are created equal, and the specific model required can impact the price. Some units are basic models that only measure breath alcohol content, while others are more advanced, featuring cameras, GPS tracking, and real-time data reporting to the monitoring agency. The requirement for these enhanced features, often dictated by a high-risk classification from the court, will drive the rental fee higher. Additionally, some providers charge extra for the initial calibration kit or for mandatory compliance checks, which are usually performed at the provider's service centers.
Additional Fees to Consider
Installation Fees: While often included in the initial package, some providers may charge extra if the vehicle is difficult to access or requires additional wiring.
Removal and Transfer Fees: When the restriction period ends, a fee is usually charged to remove the device. If the driver needs to transfer the device to a different vehicle or state during the program, there may be a separate charge.
Retest Fees: If the driver fails a rolling retest or has a violation, some companies impose administrative fees to cover the additional review of the data.
The Cost of Non-Compliance
While it is important to understand the financial burden of the device, it is equally important to view it as a legal obligation rather than a mere expense. Failure to maintain the interlock device, missing a calibration appointment, or attempting to bypass the system results in severe consequences. These penalties include extended ignition interlock periods, hefty fines from the DMV, and potential jail time. The cost of these violations significantly outweighs the monthly rental fee, making consistent compliance the most financially sensible path forward.
Finding the Right Balance
When comparing how much is an interlock device across different companies, price should not be the only deciding factor. Look for a provider with a strong reputation for reliability and excellent customer service, as a malfunctioning device can lead to legal trouble. Verify that the provider is certified by your state’s DMV and that their pricing is transparent. Understanding the full breakdown of installation, monthly rental, and potential hidden fees ensures that there are no surprises during what is already a challenging time.
