What Is Driving with a BAC of 0.08% or Greater?

Driving with a blood alcohol concentration (BAC) of 0.08% or greater is a criminal offense that qualifies as Driving Under the Influence (DUI) in California and throughout the U.S.

At this level of intoxication, it is presumed that a driver’s ability to operate a vehicle safely is impaired—even if they don’t appear visibly drunk. This “per se” DUI law means that a BAC of 0.08% or higher automatically violates the law, regardless of driving behavior.

How BAC Is Measured

BAC is typically determined through:

• Breathalyzer tests administered roadside or at the police station
• Blood tests taken after arrest
• Urine tests in limited cases (usually when blood tests aren’t possible)

Law enforcement uses these tests to confirm the level of alcohol in a driver’s bloodstream.

Penalties for Driving with a BAC of 0.08% or Greater

Penalties depend on the number of prior offenses, the driver’s record, and whether the incident involved injuries or property damage.

For a First Offense:

• Fines ranging from $390 to over $1,000 (plus court costs)
• 48 hours to 6 months in county jail
• 6-month driver’s license suspension
• Mandatory DUI school (3 to 9 months)
• Probation of up to 3 years

For Repeat Offenses or Aggravated Cases:

• Up to 1 year in jail
• 2-year or longer license suspension
• Mandatory installation of an ignition interlock device (IID)
• Increased fines and extended probation

If the DUI caused injuries or fatalities, it may be charged as a felony, leading to longer prison sentences and higher fines.

Bail for DUI with 0.08% BAC or Higher

Bail for DUI cases varies based on the severity and location of the offense:

• Standard DUI (No Injury): $5,000–$10,000
• DUI with Accident or Injury: $25,000–$50,000
• Felony DUI: $100,000 or more

Posting bail allows the defendant to leave jail and prepare for court while ensuring they appear for all hearings.

How a Bail Bond Can Help

If you can’t afford to pay the full bail amount, a bail bond is an affordable alternative.

A licensed bail bond agent can:

• Post bail on your behalf for a non-refundable fee—usually 10% of the total bail
• Handle all paperwork and coordinate with the jail
• Ensure you’re released quickly, often within hours

This allows you or your loved one to return home and begin preparing for the case with legal counsel.
