Questions We Get Asked
What is the legal BAC limit?
There is no single national limit; each state draws its own line for blood alcohol concentration (BAC). For adults driving a passenger car, many states use 0.08%, while commercial drivers and drivers under 21 usually face a lower threshold. Confirm the number in California's vehicle code, and keep in mind that impairment can set in below the legal limit.
What are the penalties for a first DUI?
A first DUI or DWI conviction commonly brings fines, a suspended license, the possibility of jail, required substance-abuse classes, and an ignition interlock device. What you actually face in California turns on your BAC, whether anyone was hurt, and whether you have earlier offenses.
Can you refuse a breathalyzer?
Implied consent laws exist in most states: driving is treated as agreement to chemical testing after a lawful DUI arrest. Turning down a test in California can trigger an automatic license suspension and other sanctions that apply separately from any DUI conviction.
How long does a DUI stay on your record?
How long a DUI lingers on a driving or criminal record depends on where you are. Some states let it be expunged after several years; elsewhere it stays for life. Look at California's motor vehicle records and expungement laws for the specifics.
