In Hong Kong and around the world, numerous road accidents are caused by drink driving, leading to many minor and serious casualties and deaths. Currently in most cities, drivers are breathalyzed only after an accident or a driving offence. However, this would often come too late in preventing accidents at the first place. This research is to confer and design an Advanced Version Anti-drink Driving Device (AVADD) to effectively prevent drink driving. The research proceeded according to the design process. After the tests, we analyzed the merits and the weaknesses of the products available in the market. We designed and made a competitive finished product. AVADD will be a sophisticated and unique device. It consists of three components, a breathalyzer, a body sensor and an air-extracting device. By fitting a breathalyzer to the ignition system, the ignition will be automatically locked and vehicle cannot be started if the driver has a breath alcohol concentration above a pre-set safety level. The sensor is installed on the steering wheel to ensure drivers grip the wheel instead of holding other devices, such as air plumps that may possibly cheat the system. The air-extracting apparatus is an independent testing device which constantly checks the alcohol vapour concentration level inside the vehicle to avoid others starting the cars. If it detects a high concentration level, it will set off an indicator to alert other drivers and the police. The effectiveness of AVADD is surely better than any other similar products in the market.
