How LifeSafer Ignition Interlock Devices Work 

An ignition interlock device is installed in a vehicle and prevents that vehicle from being started if alcohol 

is detected. The driver is required to submit a passing BrAC (Breath Alcohol Concentration) sample for 

the vehicle to start. 

The LifeSafer device is the industry leader in accuracy, reliability, and ease-of-use. 

• Smallest, most discreet device on the market

• Blow-hum-blow method helps to eliminate contaminants that could cause false positives 
• Simple display to show results 
• Constantly updated to use the newest, most accurate technology available 
• Most efficient internal heaters to help precent car battery drain you’ll experience with other devices 
• Device can be programmed to warm up ahead of time, unlike other brands
