Drunk driving is really a big NO anywhere in the world that is why many countries are doing their best to implement traffic safety and apprehend violators. Just lately, I learned about alcohol saliva test strips. These strips can easily detect the level of alcohol in one’s body. It can easily tell that a person is drunk or even under the influence of alcohol. I haven’t seen it yet but I think it is a good invention. I think it is also convenient for cops to bring.
