#1 Alcohol Monitoring Devices
Believe it or not, all Ignition Interlock Devices (IIDs) are not created equal. While some car breathalyzer brands boast affordability, quality and safety are often overlooked. Every product that Smart Start manufactures is not only affordable but also designed with your safety and usability as our main objective. In fact, Smart Start thoroughly tests every interlock device to ensure that it exceeds the National Highway Traffic Safety Administration (NHTSA) standards, keeping you safe while you travel. The sleek and discreet design fits comfortably anywhere in your vehicle. Expect only the most accurate results so you never have to worry about false positive readings. Since 1992, millions of customers have trusted Smart Start for the best Ignition Interlock Device nationwide.
