The technology measures a driver's alcohol level through the use of infrared light. Their blood alcohol content is determined by placing their finer on or near an infrared sensor that analyzes the alcohol concentration in his or her body. If their blood alcohol content is found to be over the legal limit, the car will not start. Accurate results are available in seconds, and a built-in biometric system prevents tampering. The product would require no user training and no operator assistance.
In-car breathalyzers and ignition interlock systems have been used in some capacity for the past few decades to minor success. A tool like the Takata-TruTouch would be easier to operate and also more difficult to tamper with.
“An ounce of prevention is worth more than a pound of cure,” is the Takata-TruTouch company philosophy. As a Virginia injury lawyer, I couldn't agree more. By placing technology like this in every car in the country, imagine how many lives could be saved. Though this product is still in the beginning stages of development, it's easy to see what a big impact it could have on our society.
