In order to prevent accidents ALL vehicles should be equipped with a breath analyzer. The driver has to give a breath sample before he starts the engine. If alcohol is consumed beyond the limit, the vehicle engine will not start and if the breath sample doesn't contain alcohol then the engine circuit will be closed and the vehicle will start. This system will be linked to the police station through Cloud data and Internet of Things (IOT). Vehicle drivers will be provided with an emergency switch in that case they can start the vehicle without providing breath sample, by doing this so they agree that they are not drunk; vehicle details will be linked to nearest police station.
Secondly, in Google maps speed limit of each area has to be stored. The vehicle should have a GPS system if the speed limit of the vehicle crosses the limit the vehicle details will be sent to nearest police station.
By following these ideas accidents can be reduced.
