Road traffic safety solution

This paper comes as a response to the fact that lately more and more accidents are caused by people who drive while intoxicated. Drunk drivers are not able to manage the wheel and make the most basic movements required when driving. This often puts their life and other traffic participants´ lives in peril. The proposed system, four alcohol sensors based, can determine if and who has been drinking (the driver or one of the passengers) and it will signal visual and auditive warnings.
