More than one drink may soon be too much and could lead to a DUI arrest. As many know, the legal driving limit in California is a blood alcohol concentration (BAC) of less than 0.08%. This level was drastically lowered from 0.15% in the 1980s and may now be lowered again.
The National Transportation Safety Board (NTSB) has recommended that the limit be lowered to 0.05%. Although the NTSB has no authority to make changes itself, it is an influential agency, and can encourage lawmakers to make changes in their respective states, as well as provide financial incentives for states to adopt their suggestions.
