37.4% of Fatalities Traffic Crashes are due to drivers that have previously
consumed alcohol, without a doubt, thousands of people would’ve still be alive if
these drivers were prohibit to start their car after alcohol consumption. Being part
of a group that’s most likely to drink and drive and we all have personal
experience of losing close ones due to drunk driving, therefore we vowed to take
action by designing a better ignition interlock system with wireless alcohol
sensor. This sophisticated device can prevent a vehicle from being driven by a
drunk driver and will decrease the death rates due to drunk driving significantly.
