Abstract

Recently, cases of fatal traffic accidents involving inebriated drivers have been often reported in the news. This issue has not only endangered the safety of drivers but also other road users. In a state of drunk, human beings are not ready to work, think rationally and evaluate things accurately. A study conducted by the World Health Organization (WHO) in 2018, between 2010 and 2018 showed that there were 2364 drunk drivingrelated accidents resulting in 1196 deaths. On average, each year, a total of 132 people are killed and the ratio of drunk driver-related accidents is one person killed for every three days. According to the WHO report, Malaysia is one of the 35 countries that contribute to the high rate of accidents involving drunk driving. Drunk driving has been listed as one of the leading factors in fatal car accidents. To overcome this problem, drunk driving detectors have the potential to be explored to reduce the rate of road accidents. Many studies have been done to create vehicle driver alcohol limit detectors. However, there are still many shortcomings that need to be fixed. In this study, a drunk driving detection device was introduced using a microcontroller embedded into the vehicle start system. Alcohol sensors were used in this study to detect alcohol levels in human breath. The device will initially detect the level of alcohol in the breath and when the alcohol concentration is detected in excess of 50 milligrams per 100 millimeters of blood, the car’s starting system is stopped so that the car cannot be started. Next, the driver’s window will slide down automatically by 20mm for the purpose of ventilation in the vehicle cabin. With the use of this system, road accidents caused by drunk drivers can be reduced. In addition, a driver who is intoxicated can rest in the car cabin until he is awake from the state of intoxication without drowning in the car cabin.
