North America Ignition Interlock Devices Market Size, Share, and Growth Forecast for 2025 - 2032

North America Ignition Interlock Devices Market Size and Share Analysis

The North America ignition interlock devices market is estimated to reach a size of US$ 668.9 Mn in 2025. It is projected to rise at a CAGR of 8.1% through the assessment period to attain a value of US$ 1,153.8 Mn by 2032. The U.S. market share was recorded at 58.9% in 2024.

The ignition interlock device is an advanced breathalyzer installed in vehicles to measure the blood alcohol content (BAC) of the driver, wherein the driver needs to blow breath into the device to give his breath sample. If the alcohol content in the breath sample is more than pre-set limit of the device, the vehicle would not start. The ignition interlock device is used as a tool against drunk driving.

IID can be used in fleet safety and public transportation as an additional measure of safety to protect and prevent damage to people and property. Furthermore, IID is linked to the vehicle dashboard, which is easily accessible from the driver's seat.

Increased instances of drink-driving and a sharp increase in the number of accidents, as a result, have made the installation of ignition interlock devices a mandatory safety standard across North America.

The market in the US held the largest market share of 58.9% in 2024 and is expected to retain its dominant position throughout the forecast period and demand for the ignition interlock devices market in Canada held a 41.1% value share in the market in 2024.
