The following chart summarizes California DUI Alcohol Percentages where you will find more details on these DUI blood alcohol content (BAC) limits, including relevant statutes.
It is organized in ascending order, with the lowest levels first. Note that the following refers to BAC levels within three hours of driving (i.e. within three hours of the traffic stop).
| BAC level | Applies to | DUI offense |
| Not specified* | All drivers | Driving Under the Influence * No specific BAC level – the charge may be supported by “other competent evidence” of drunk driving (i.e. officer observations). This means you may be arrested and convicted of DUI regardless of your actual BAC level. (In practice, if it is less than 0.05 you will most likely be found “not guilty” – unless an offense with a BAC level of less than 0.05 also applies.) |
