Drunk driving can be stopped in many ways, but one of the biggest ways is by having breathalyzers installed into all cars. Breathalyzers are devices that put cars into ignition interlock when a person with illegal amount of driving levels of alcohol in their system. Their car wont start if they breath into it and they have too much alcohol in their system. Drunk driving is a big deal and needs to be stopped. Ergo, breathalyzers is the best thing to stop drunk driving.
