All right, I apologize. I believe you. But there are a lot of people who are not as responsible as you are.
It has been demonstrated that people at .05 are impaired. If you have never driven drunk or impaired, then you shouldn't have any problem with lowering the limit to .05. Right?
It has been demonstrated...by who?
If a person is too dangerous to drive at .05...then surely they are at .04 also.
I have little doubt, in fact I know for a fact that a person with little alcohol tolerance is impaired at .05...and less. But that is a small-small percentage of the population.
There are many people who are light sensitive. I am one of them, it is definitely a traffic hazard for me to drive at night on a two lane highway, and all others like me. But it is not illegal.
People with sleep disorders can be seriously impaired, but it is not illegal.
People who are deaf are certainly impaired, but they can drive.
People blind in one eye are impaired, but drive.
Point being, and the actual subject at hand, when is "impaired" an actual danger. Like I say, if .05 is...then how is .04 not? And is .05 less dangerous than a person with sleep disorder, or someone who just pulled a 16 hour shift????
