When they lower the limit to .03, it means you better not use mouthwash. You could be legally drunk.
In another look at it, people can no longer walk to the neighborhood bar to enjoy a drink and a smoke. This doesn't excuse them getting drunk and driving, but what used to be a skinned knee and a bump on the head for the walker is now a major traffic incident.
Unintended consequences of bad laws.
If I were King of the World the BAC limit would be raised to .12 and punishment would be graduated upwards depending on BAC.
Thus a person with .12 would get a ticket and a person with .20 would do time in the slammer.
But blaming smoking bans for an increase in DWI deaths in nuts.
What next, are we going to blame developers who build houses way out in the suburbs? After all, if I live way out in the suburbs I have to drive 30 miles to get home after a night of drinking. If I live in town, I can just walk a few blocks.
