Good for you. Unfortunately, the legislature in New Hampshire already lowered the accepted BAC to 0.02 for young drivers and to 0.04 for commercial drivers.
Were the MADD members in New Hampshire opposed to it? I wonder if you can find out, since you seem to be involved with the MADD crowd.
I don't do anything more than Local with Madd but I would be happy to ask the folks I know about it.
We also have limits for CDL drivers here that is lower than .08. For that circumstance I agree with it. 50 tons driving down the road should not be taken lightly....sorry about the pun.
